The Future of the Web: BBC Interview

The BBC World Service’s Business Daily show interviewed the CTO of Xerox and me, about the future of the Web, printing, newspapers, search, personalization, the real-time Web. Listen to the audio stream here. I hear this will only be online at this location for 6 more days. If anyone finds it again after that let me know and I’ll update the link here.

The Next Generation of Web Search — Search 3.0

The next generation of Web search is coming sooner than expected. And with it we will see several shifts in the way people search, and the way major search engines provide search functionality to consumers.

Web 1.0, the first decade of the Web (1989 – 1999), was characterized by a distinctly desktop-like search paradigm. The overriding idea was that the Web is a collection of documents, not unlike the folder tree on the desktop, that must be searched and ranked hierarchically. Relevancy was considered to be how closely a document matched a given query string.

Web 2.0, the second decade of the Web (1999 – 2009), ushered in the beginnings of a shift towards social search. In particular blogging tools, social bookmarking tools, social networks, social media sites, and microblogging services began to organize the Web around people and their relationships. This added the beginnings of a primitive “web of trust” to the search repertoire, enabling search engines to begin to take the social value of content (as evidences by discussions, ratings, sharing, linking, referrals, etc.) as an additional measurment in the relevancy equation. Those items which were both most relevant on a keyword level, and most relevant in the social graph (closer and/or more popular in the graph), were considered to be more relevant. Thus results could be ranked according to their social value — how many people in the community liked them and current activity level — as
well as by semantic relevancy measures.

In the coming third decade of the Web, Web 3.0 (2009 – 2019), there will be another shift in the search paradigm. This is a shift to from the past to the present, and from the social to the personal.

Established search engines like Google rank results primarily by keyword (semantic) relevancy. Social search engines rank results primarily by activity and social value (Digg, Twine 1.0, etc.). But the new search engines of the Web 3.0 era will also take into account two additional factors when determining relevancy: timeliness, and personalization.

Google returns the same results for everyone. But why should that be the case? In fact, when two different people search for the same information, they may want to get very different kinds of results. Someone who is a novice in a field may want beginner-level information to rank higher in the results than someone who is an expert. There may be a desire to emphasize things that are novel over things that have been seen before, or that have happened in the past — the more timely something is the more relevant it may be as well.

These two themes — present and personal — will define the next great search experience.

To accomplish this, we need to make progress on a number of fronts.

First of all, search engines need better ways to understand what content is, without having to do extensive computation. The best solution for this is to utilize metadata and the methods of the emerging semantic web.

Metadata reduces the need for computation in order to determine what content is about — it makes that explicit and machine-understandable. To the extent that machine-understandable metadata is added or generated for the Web, it will become more precisely searchable and productive for searchers.

This applies especially to the area of the real-time Web, where for example short “tweets” of content contain very little context to support good natural-language processing. There a little metadata can go a long way. In addition, of course metadata makes a dramatic difference in search of the larger non-real-time Web as well.

In addition to metadata, search engines need to modify their algorithms to be more personalized. Instead of a “one-size fits all” ranking for each query, the ranking may differ for different people depending on their varying interests and search histories.

Finally, to provide better search of the present, search has to become more realtime. To this end, rankings need to be developed that surface not only what just happened now, but what happened recently and is also trending upwards and/or of note. Realtime search has to be more than merely listing search results chronologically. There must be effective ways to filter the noise and surface what’s most important effectively. Social graph analysis is a key tool for doing this, but in
addition, powerful statistical analysis and new visualizations may also be required to make a compelling experience.

Video: My Talk on The Future of Libraries — "Library 3.0"

If you are interested in semantics, taxonomies, education, information overload and how libraries are evolving, you may enjoy this video of my talk on the Semantic Web and the Future of Libraries at the OCLC Symposium at the American Library Association Midwinter 2009 Conference. This event focused around a dialogue between David Weinberger and myself, moderated by Roy Tennant. We were forutnate to have an audience of about 500 very vocal library directors in the audience and it was an intensive day of thinking together. Thanks to the folks at OCLC for a terrific and really engaging event!

Twine's Explosive Growth

Twine has been growing at 50% per month since launch in October. We've been keeping that quiet while we wait to see if it holds. VentureBeat just noticed and did an article about it. It turns out our January numbers are higher than Compete.com estimates and February is looking strong too. We have a slew of cool viral features coming out in the next few months too as we start to integrate with other social networks. Should be an interesting season.

Fast Company Interview — "Connective Intelligence"

In this interview with Fast Company, I discuss my concept of "connective intelligence." Intelligence is really in the connections between things, not the things themselves. Twine facilitates smarter connections between content, and between people. This facilitates the emergence of higher levels of collective intelligence.

Interest Networks are at a Tipping Point

UPDATE: There’s already a lot of good discussion going on around this post in my public twine.

I’ve been writing about a new trend that I call “interest networking” for a while now. But I wanted to take the opportunity before the public launch of Twine on Tuesday (tomorrow) to reflect on the state of this new category of applications, which I think is quickly reaching its tipping point. The concept is starting to catch on as people reach for more depth around their online interactions.

In fact – that’s the ultimate value proposition of interest networks – they move us beyond the super poke and towards something more meaningful. In the long-term view, interest networks are about building a global knowledge commons. But in the short term, the difference between social networks and interest networks is a lot like the difference between fast food and a home-cooked meal – interest networks are all about substance.

At a time when social media fatigue is setting in, the news cycle is growing shorter and shorter, and the world is delivered to us in soundbytes and catchphrases, we crave substance. We go to great lengths in pursuit of substance. Interest networks solve this problem – they deliver substance.t

So, what is an interest network?

In short, if a social network is about who you are interested in, an interest network is about what you are interested in. It’s the logical next step.

Twine for example, is an interest network that helps you share information with friends, family, colleagues and groups, based on mutual interests. Individual “twines” are created for content around specific subjects. This content might include bookmarks, videos, photos, articles, e-mails, notes or even documents. Twines may be public or private and can serve individuals, small groups or even very large groups of members.

I have also written quite a bit about the Semantic Web and the Semantic Graph, and Tim Berners-Lee has recently started talking about what he calls the GGG (Giant Global Graph). Tim and I are in agreement that social networks merely articulate the relationships between people. Social networks do not surface the equally, if not more important, relationships between people and places, places and organizations, places and other places, organization and other organizations, organization and events, documents and documents, and so on.

This is where interest networks come in. It’s still early days to be clear, but interest networks are operating on the premise of tapping into a multi–dimensional graph that manifests the complexity and substance of our world, and delivers the best of that world to you, every day.

We’re seeing more and more companies think about how to capitalize on this trend. There are suddenly (it seems, but this category has been building for many months) lots of different services that can be viewed as interest networks in one way or another, and here are some examples:

What all of these interest networks have in common is some sort of a bottom-up, user-driven crawl of the Web, which is the way that I’ve described Twine when we get the question about how we propose to index the entire Web (the answer: we don’t.

We let our users tell us what they’re most interested in, and we follow their lead).

Most interest networks exhibit the following characteristics as well:

  • They have some sort of bookmarking/submission/markup function to store and map data (often using existing metaphors, even if what’s under the hood is new)
  • They also have some sort of social sharing function to provide the network benefit (this isn’t exclusive to interest networks, obviously, but it is characteristic)
  • And in most cases, interest networks look to add some sort of “smarts” or “recommendations” capability to the mix (that is, you get more out than you put in)

This last bullet point is where I see next-generation interest networks really providing the most benefit over social bookmarking tools, wikis, collaboration suites and pure social networks of one kind or another.

To that end, we think that Twine is the first of a new breed of intelligent applications that really get to know you better and better over time – and that the more you use Twine, the more useful it will become. Adding your content to Twine is an investment in the future of your data, and in the future of your interests.

At first Twine begins to enrich your data with semantic tags and links to related content via our recommendations engine that learns over time. Twine also crawls any links it sees in your content and gathers related content for you automatically – adding it to your personal or group search engine for you, and further fleshing out the semantic graph of your interests which in turn results in even more relevant recommendations.

The point here is that adding content to Twine, or other next-generation interest networks, should result in increasing returns. That’s a key characteristic, in fact, of the interest networks of the future – the idea that the ratio of work (input) to utility (output) has no established ceiling.

Another key characteristic of interest networks may be in how they monetize. Instead of being advertising-driven, I think they will focus more on a marketing paradigm. They will be to marketing what search engines were to advertising. For example, Twine will be monetizing our rich model of individual and group interests, using our recommendation engine. When we roll this capability out in 2009, we will deliver extremely relevant, useful content, products and offers directly to users who have demonstrated they are really interested in such information, according to their established and ongoing preferences.

6 months ago, you could not really prove that “interest networking” was a trend, and certainly it wasn’t a clearly defined space. It was just an idea, and a goal. But like I said, I think that we’re at a tipping point, where the technology is getting to a point at which we can deliver greater substance to the user, and where the culture is starting to crave exactly this kind of service as a way of making the Web meaningful again.

I think that interest networks are a huge market opportunity for many startups thinking about what the future of the Web will be like, and I think that we’ll start to see the term used more and more widely. We may even start to see some attention from analysts — Carla, Jeremiah, and others, are you listening?

Now, I obviously think that Twine is THE interest network of choice. After all we helped to define the category, and we’re using the Semantic Web to do it. There’s a lot of potential in our engine and our application, and the growing community of passionate users we’ve attracted.

Our 1.0 release really focuses on UE/usability, which was a huge goal for us based on user feedback from our private beta, which began in March of this year. I’ll do another post soon talking about what’s new in Twine. But our TOS (time on site) at 6 minutes/user (all time) and 12 minutes/user (over the last month) is something that the team here is most proud of – it tells us that Twine is sticky, and that “the dogs are eating the dog food.”

Now that anyone can join, it will be fun and gratifying to watch Twine grow.

Still, there is a lot more to come, and in 2009 our focus is going to shift back to extending our Semantic Web platform and turning on more of the next-generation intelligence that we’ve been building along the way. We’re going to take interest networking to a whole new level.

Stay tuned!

The Future of the Desktop

This is an older version of this article. The most recent version is located here:

http://www.readwriteweb.com/archives/future_of_the_desktop.php

—————

I have spent the last year really thinking about the future of the Web. But lately I have been thinking more about the future of the desktop. In particular, here are some questions I am thinking about and some answers I’ve come up so far.

(Author’s Note: This is a raw, first-draft of what I think it will be like. Please forgive any typos — I am still working on this and editing it…)

What Will Happen to the Desktop?

As we enter the third decade of the Web we are seeing an increasing shift from local desktop applications towards Web-hosted software-as-a-service (SaaS). The full range of standard desktop office tools (word processors, spreadsheets, presentation tools, databases, project management, drawing tools, and more) can now be accessed as Web-hosted apps within the browser. The same is true for an increasing range of enterprise applications. This process seems to be accelerating.

As more kinds of applications become available in Web-based form, the Web browser is becoming the primary framework in which end-users work and interact. But what will happen to the desktop? Will it too eventually become a Web-hosted application? Will the Web browser swallow up the desktop? Where is the desktop headed?

Is the desktop of the future going to just be a web-hosted version of the same old-fashioned desktop metaphors we have today?

No. There have already been several attempts at doing this — and they never catch on. People don’t want to manage all their information on the Web in the same interface they use to manage data and apps on their local PC.

Partly this is due to the difference in user experience between using files and folders on a local machine and doing that in “simulated” fashion via some Flash-based or HTML-based imitation of a desktop. Imitations desktops to-date have simply been clunky and slow imitations of the real-thing at best. Others have been overly slick. But one thing they all have in common: None of them have nailed it. The desktop of the future – what some have called “the Webtop” – still has yet to be invented.

It’s going to be a hosted web service

Is the desktop even going to exist anymore as the Web becomes increasingly important? Yes, there will have to be some kind of interface that we consider to be our personal “home” and “workspace” — but ultimately it will have to be a unified space that all our devices connect to and share. This requires that it be a hosted online service.

Currently we have different information spaces on different devices (laptop, mobile device, PC). These will merge. Native local clients could be created for various devices, but ultimately the simplest and therefore most likely choice is to just use the browser as the client. This coming “Webtop” will provide an interface to your local devices, applications and information, as well as to your online life and information.

Today we think of our Web browser running inside our desktop as an applicaiton. But actually it will be the other way around in the future: Our desktop will run inside our browser as an application.

Instead of the browser running inside, or being launched from, some kind of next-generation desktop web interface technology, it’s will be the other way around: The browser will be the shell and the desktop application will run within it either as a browser add-in, or as a web-based application.

The Web 3.0 desktop is going to be completely merged with the Web — it is going to be part of the Web. In fact there may eventually be no distinction between the desktop and the Web anymore.

The focus shifts from information to attention

As our digital lives shift from being focused on the old fashioned desktop to the Web environment we will see a shift from organizing information spatially (directories, folders, desktops, etc.) to organizing information temporally (feeds, lifestreams, microblogs, timelines, etc.).

Instead of being just a directory, the desktop of the future is going to be more like a feed reader or social news site. The focus will be on keeping up with all the stuff flowing in and out of the user’s environment. The interface will be tuned to help the user understand what the trends are, rather than just on how things are organized.

The focus will be on helping the user to manage their attention rather than just their information. This is a leap to the meta-level: A second-order desktop. Instead of just being about the information (the first-order), it is going to be about what is happening with the information (the second-order).

Users are going to shift from acting as librarians to acting as daytraders.

Our digital roles are already shifting from acting as librarians to becoming more like daytraders. In the PC era we were all focused on trying to manage the stuff on our computers — in other words, we were acting as librarians. But this is going to shift. Librarians organize stuff, but daytraders are focused on discovering and keeping track of trends. It’s a very different focus and activity, and it’s what we are all moving towards.

We are already spending more of our time keeping up with change and detecting trends, than on organizing information. In the coming decade the shelf-life of information is going to become vanishingly short and the focus will shift from storage and recall to real-time filtering, trend detection and prediction.

The Webtop will be more social and will leverage and integrate collective intelligence

The Webtop is going to be more socially oriented than desktops of today — it will have built-in messaging and social networking, as well as social-media sharing, collaborative filtering, discussions, and other community features.

The social dimension of our lives is becoming perhaps our most important source of information. We get information via email from friends, family and colleagues. We get information via social networks and social media sharing services. We co-create information with others in communities.

The social dimension is also starting to play a more important role in our information management and discovery activities. Instead of those activities remaining as solitary, they are becoming more communal. For example many social bookmarking and social news sites use community sentiment and collaborative filtering to help to highlight what is most interesting, useful or important.

It’s going to have powerful semantic search and social search capabilities built-in

The Webtop is going to have more powerful search built-in. This search will combine both social and semantic search features. Users will be able to search their information and rank it by social sentiment (for example, “find documents about x and rank them by how many of my friends liked them.”)

Semantic search will enable highly granular search and navigation of information along a potentially open-ended range of properties and relationships.

For example you will be able to search in a highly structured way — for example, search for products you once bookmarked that have a price of $10.95 and are on-sale this week. Or search for documents you read which were authored by Sue and related to project X, in the last month.

The semantics of the future desktop will be open-ended. That is to say that users as well as other application and information providers will be able to extend it with custom schemas, new data types, and custom fields to any piece of information.

Interactive shared spaces instead of folders

Forget about shared folders — that is an outmoded paradigm. Instead, the  new metaphor will be interactive shared spaces.

The need for shared community space is currently being provided for online by forums, blogs, social network profile pages, wikis, and new community sites. But as we move into Web 3.0 these will be replaced by something that combines their best features into one. These next-generation shared spaces will be like blogs, wikis, communities, social networks, databases, workspaces and search engines in one.

Any group of two or more individuals will be able to participate in a shared space that connects their desktops for a particular purpose. These new shared spaces will not only provide richer semantics in the underlying data, social network, and search, but they will also enable groups to seamlessly and collectively add, organize, track, manage, discuss, distribute, and search for information of mutual interest.

The personal cloud

The future desktop will function like a “personal cloud” for users. It will connect all their identities, data, relationships, services and activities in one virtual integrated space. All incoming and outgoing activity will flow through this space. All applications and services that a user makes use of will connect to it.

The personal cloud may not have a center, but rather may be comprised of many separate sub-spaces, federated around the Web and hosted by different service-providers. Yet from an end-user perspective it will function as a seamlessly integrated service. Users will be able to see and navigate all their information and applications, as if they were in one connected space, regardless of where they are actually hosted. Users will be able to search their personal cloud from any point within it.

Open data, linked data and open-standards based semantics

The underlying data in the future desktop, and in all associated services it connects, will be represented using open-standard data formats. Not only will the data be open, but the semantics of the data – the schema – will also be defined in an open way. The emerigng Semantic Web provides a good infrastructure for enabling this to happen.

The value of open linked-data and open semantics is that data will not be held prisoner anywhere and can easily be integrated with other data.

Users will be able to seamlessly move and integrate their data, or parts of their data, in different services. This means that your Webtop might even be portable to a different competing Webtop provider someday. If and when that becomes possible, how will Webtop providers compete to add value?

It’s going to be smart

One of the most important aspects of the coming desktop is that it’s going to be smart. It’s going to learn and help users to be more productive. Artificial intelligence is one of the key ways that competing Webtop providers will differentiate their offerings.

As you use it, it’s going to learn about your interests, relationships, current activities, information and preferences. It will adaptively self-organize to help you focus your attention on what is most important to whatever context you are in.

When reading something while you are taking a trip to Milan it may organize itself to be more contextually relevant to that time, place and context. When you later return home to San Francisco it will automatically adapt and shift to your home context. When you do a lot of searches about a certain product it will realize your context and intent has to do with that product and will adapt to help you with that activity for a while, until your behavior changes.

Your desktop will actually be a semantic knowledge base on the back-end. It will encode a rich semantic graph of your information, relationships, interests, behavior and preferences. You will be able to permit other applications to access part or all of your graph to datamine it and provide you with value-added views and even automated intelligent assistance.

For example, you might allow an agent that cross-links things to see all your data: it would go and add cross links to relevant things onto all the things you have created or collected. Another agent that makes personalized buying recommendations might only get to see your shopping history across all shopping sites you use.

Your desktop may also function as a simple personal assistant at times. You will be able to converse with your desktop eventually — through a conversational agent interface. While on the road you will be able to email or SMS in questions to it and get back immediate intelligent answers. You will even be able to do this via a voice interface.

For example, you might ask, “where is my next meeting?” or “what Japanese restaurants do I like in LA?” or “What is Sue’s Smith’s phone number?” and you would get back answers. You could also command it to do things for you — like reminding you to do something, or helping you keep track of an interest, or monitoring for something and alerting you when it happens.

Because your future desktop will connect all the relationships in your digital life — relationships connecting people, information, behavior, prefences and applications — it will be the ultimate place to learn about your interests and preferences.

Federated, open policies and permissions

This rich graph of meta-data that comprises your future desktop will enable the next-generation of smart services to learn about you and help you in an incredibly personalized manner. It will also of course be rife with potential for abuse and privacy will be a major function and concern.

One of the biggest enabling technologies that will be necessary is a federated model for sharing meta-data about policies and permissions on data. Information that is considered to be personal and private in Web site X should be recognized and treated as such by other applications and websites you choose to share that information with. This will require a way for sharing meta-data about your policies and permissions between different accounts and applicaitons you use.

The semantic web provides a good infrastructure for building and deploying a decentralized framework for policy and privacy integration, but it has yet to be developed, let alone adopted. For the full vision of the future desktop to emerge a universally accepted standard for exchanging policy and permission data will be a necessary enabling technology.

Who is most likely to own the future desktop?

When I think about what the future desktop is going to look like it seems to be a convergence of several different kinds of services that we currently view as separate.

It will be hosted on the cloud and accessible across all devices. It will place more emphasis on social interaction, social filtering, and collective intelligence. It will provide a very powerful and extensible data model with support for both unstructured and arbitrarily structured information. It will enable almost peer-to-peer like search federation, yet still have a unified home page and user-experience. It will be smart and personalized. It will be highly decentralized yet will manage identity, policies and permissions in an integrated cohesive and transparent manner across services.

By cobbling together a number of different services that exist today you could build something like this in a decentralized fashion. Is that how the desktop of the future will come about? Or will it be a new application provided by one player with a lot of centralized market power? Or could an upstart suddently emerge with the key enabling technologies to make this possible? It’s hard to predict, but one thing is certain: It will be an interesting process to watch.

Great Collective Intelligence Book; Includes a Chapter I Wrote

I highly recommend this new book on Collective Intelligence. It features chapters by a Who’s Who of thinkers on Collective Intelligence, including a chapter by me about “Harnessing the Collective Intelligence of the World Wide Web.”

Here is the full-text of my chapter, minus illustrations (the rest of the book is great and I suggest you buy it to have on your shelf. It’s a big volume and worth the read):

My Visit to DERI — World's Premier Semantic Web Research Institute

Earlier this month I had the opportunity to visit, and speak at, the Digital Enterprise Research Institute (DERI), located in Galway, Ireland. My hosts were Stefan Decker, the director of the lab, and John Breslin who is heading the SIOC project.

DERI has become the world’s premier research institute for the Semantic Web. Everyone working in the field should know about them, and if you can, you should visit the lab to see what’s happening there.

Part of the National University of Ireland, Galway. With over 100 researchers focused solely on the Semantic Web, and very significant financial backing, DERI has, to my knowledge, the highest concentration of Semantic Web expertise on the planet today. Needless to say, I was very impressed with what I saw there. Here is a brief synopsis of some of the projects that I was introduced to:

  • Semantic Web Search Engine (SWSE) and YARS, a massively scalable triplestore.  These projects are concerned with crawling and indexing the information on the Semantic Web so that end-users can find it. They have done good work on consolidating data and also on building a highly scalable triplestore architecture.
  • Sindice — An API and search infrastructure for the Semantic Web. This project is focused on providing a rapid indexing API that apps can use to get their semantic content indexed, and that can also be used by apps to do semantic searches and retrieve semantic content from the rest of the Semantic Web. Sindice provides Web-scale semantic search capabilities to any semantic application or service.
  • SIOC — Semantically Interlinked Online Communities. This is an ontology for linking and sharing data across online communities in an open manner, that is getting a lot of traction. SIOC is on its way to becoming a standard and may play a big role in enabling portability and interoperability of social Web data.
  • JeromeDL is developing technology for semantically enabled digital libraries. I was impressed with the powerful faceted navigation and search capabilities they demonstrated.
  • notitio.us. is a project for personal knowledge management of bookmarks and unstructured data.
  • SCOT, OpenTagging and Int.ere.st.  These projects are focused on making tags more interoperable, and for generating social networks and communities from tags. They provide a richer tag ontology and framework for representing, connecting and sharing tags across applications.
  • Semantic Web Services.  One of the big opportunities for the Semantic Web that is often overlooked by the media is Web services. Semantics can be used to describe Web services so they can find one another and connect, and even to compose and orchestrate transactions and other solutions across networks of Web services, using rules and reasoning capabilities. Think of this as dynamic semantic middleware, with reasoning built-in.
  • eLite. I was introduced to the eLite project, a large e-learning initiative that is applying the Semantic Web.
  • Nepomuk.  Nepomuk is a large effort supported by many big industry players. They are making a social semantic desktop and a set of developer tools and libraries for semantic applications that are being shipped in the Linux KDE distribution. This is a big step for the Semantic Web!
  • Semantic Reality. Last but not least, and perhaps one of the most eye-opening demos I saw at DERI, is the Semantic Reality project. They are using semantics to integrate sensors with the real world. They are creating an infrastructure that can scale to handle trillions of sensors eventually. Among other things I saw, you can ask things like "where are my keys?" and the system will search a network of sensors and show you a live image of your keys on the desk where you left them, and even give you a map showing the exact location. The service can also email you or phone you when things happen in the real world that you care about — for example, if someone opens the door to your office, or a file cabinet, or your car, etc. Very groundbreaking research that could seed an entire new industry.

In summary, my visit to DERI was really eye-opening and impressive. I recommend that major organizations that want to really see the potential of the Semantic Web, and get involved on a research and development level, should consider a relationship with DERI — they are clearly the leader in the space.

My Commentary: Radar Networks Raises $13M for Twine

I am pleased to announce that my company Radar Networks, has raised a $13M Series B investment round to grow our product, Twine. The investment comes from Velocity Interactive Group, DFJ, and Vulcan. Ross Levinsohn — the man who acquired and ran MySpace for Fox Interactive — will be joining our board. I’m very excited to be working with Ross and to have his help guiding Twine as it grows.

We are planning to use these funds to begin rolling Twine out to broader consumer markets as part of our multi-year plan to build Twine into the leading service for organizing, sharing and discovering information around interests. One of the key themes of Web 3.0 is to be help people make sense of the overwhelming amount of information and change in the online world, and at Twine, we think interests are going to play a key organizing role in that process.

Your interests comprise the portion of your information and relationships that are actually important enough that you want to keep track of them and share them with others. The question that Twine addresses is how to help individuals and groups more efficiently locate, manage and communicate around their interests in the onslaught of online information they have to cope with. The solution to information overload is not to organize all the information in the world (an impossible task), it is to help individuals and groups organize THEIR information (a much more feasible goal).

In March we are going to expand the Twine beta to begin letting more people in. Currently we have around 30,000 people on the wait-list and more coming in steadily. In March we will start letting all of these people in, gradually in waves of a few thousand at a time, and letting them invite their friends in. So to get into Twine you need to sign up on the list on the Twine site, or have a friend who is already in the service invite you in. I look forward to seeing you in Twine!

The last few months of closed beta have been very helpful in getting a lot of useful feedback and testing that has helped us improve the product in many ways. This next wave will be an exciting phase for Twine as we begin to really grow the service with more users. I am sure there will be a lot of great feedback and improvements that result from this.

However, even though we will be letting more people in soon, we are still very much in beta and will be for quite some time to come — There will still be things that aren’t finished, aren’t perfect, or aren’t there yet — so your patience will be appreciated as we continue to work on Twine over the coming year. We are letting people in to help us guide the service in the right direction, and to learn from our users. Today Twine is about 10% of what we have planned for it. First we have to get the basics right — then, in the coming year, we will really start to surface more of the power of the underlying semantic platform. We’re psyched to get all this built — what we have planned is truly exciting!

Artificial Stupidity: The Next Big Thing

There has been a lot of hype about artificial intelligence over the years. And recently it seems there has been a resurgence in interest in this topic in the media. But artificial intelligence scares me. And frankly, I don’t need it. My human intelligence is quite good, thank you very much. And as far as trusting computers to make intelligent decisions on my behalf, I’m skeptical to say the least. I don’t need or want artificial intelligence.

No, what I really need is artificial stupidity.

I need software that will automate all the stupid things I presently have to waste far too much of my valuable time on. I need something to do all the stupid tasks — like organizing email, filing documents, organizing folders, remembering things, coordinating schedules, finding things that are of interest, filtering out things that are not of interest, responding to routine messages, re-organizing things, linking things, tracking things, researching prices and deals, and the many other rote information tasks I deal with every day.

The human brain is the result of millions of years of evolution. It’s already the most intelligent thing on this planet. Why are we wasting so much of our brainpower on tasks that don’t require intelligence? The next revolution in software and the Web is not going to be artificial intelligence, it’s going to be creating artificial stupidity: systems that can do a really good job at the stupid stuff, so we have more time to use our intelligence for higher level thinking.

The next wave of software and the Web will be about making software and the Web smarter. But when we say "smarter" we don’t mean smart like a human is smart, we mean "smarter at doing the stupid things that humans aren’t good at." In fact humans are really bad at doing relatively simple, "stupid" things — tasks that don’t require much intelligence at all.

For example, organizing. We are terrible organizers. We are lazy, messy, inconsistent, and we make all kinds of errors by accident. We are terrible at tagging and linking as well, it turns out. We are terrible at coordinating or tracking multiple things at once because we are easily overloaded and we can really only do one thing well at a time. These kinds of tasks are just not what our brains are good at. That’s what computers are for – or should be for at least.

Humans are really good at higher level cognition: complex thinking, decisionmaking, learning, teaching, inventing, expressing, exploring, planning, reasoning, sensemaking, and problem solving — but we are just terrible at managing email, or making sense of the Web. Let’s play to our strengths and use computers to compensate for our weaknesses.

I think it’s time we stop talking about artificial intelligence — which nobody really needs, and fewer will ever trust. Instead we should be working on artificial stupidity. Sometimes the less lofty goals are the ones that turn out to be most useful in the end.

A Video and an Audio Cast About Twine

Last night I saw that the video of my presentation of Twine at the Web 2.0 Summit is online. My session, "The Semantic Edge," featured Danny Hillis of Metaweb demoing Freebase, Barney Pell demoing Powerset, and myself Demoing Twine, followed by a brief panel discussion with Tim O’Reilly (in that order). It’s a good panel and I recommend the video, however, the folks at Web 2.0 only filmed the presenters; they didn’t capture what we were showing on our screens, so you have to use your imagination as we describe our demos.

An audio cast of one of my presentations about Twine to a reporter was also put online recently, for a more in-depth description.

Radar Networks Announces Twine.com

My company, Radar Networks, has just come out of stealth. We’ve announced what we’ve been working on all these years: It’s called Twine.com. We’re going to be showing Twine publicly for the first time at the Web 2.0 Summit tomorrow. There’s lot’s of press coming out where you can read about what we’re doing in more detail. The team is extremely psyched and we’re all working really hard right now so I’ll be brief for now. I’ll write a lot more about this later.

Gartner is Wrong about Web 3.0

I have a lot of respect for the folks at Gartner, but their recent report in which they support the term "Web 2.0" yet claim that the term "Web 3.0" is just a marketing ploy, is a bit misguided.

In fact, quite the opposite is true.

The term Web 2.0 is in fact just a marketing ploy. It has only come to have something resembling a definition over time. Because it is in fact so ill-defined, I’ve suggested in the past that we just use it to refer to a decade: the second decade of the Web (2000 – 2010). After all there is no actual technology that is called "Web 2.0" — at best there are a whole slew of things which this term seems to label, and many of them are design patterns, not technologies. For example "tagging" is not a technology, it is a design pattern. A tag is a keyword, a string of text — there is not really any new technology there. AJAX is also not a technology in its own right, but rather a combination of technologies and design patterns, most of which existed individually before the onset of what is called Web 2.0.

In contrast, the term Web 3.0 actually does refer to a set of new technologies, and changes they will usher in during the third decade of the Web (2010 – 2020). Chief among these is the Semantic Web. The Semantic Web is actually not one technology, but many. Some of them such as RDF and OWL have been under development for years, even during the Web 2.0 era, and others such as SPARQL and GRDDL are recent emerging standards. But that is just the beginning. As the Semantic Web develops there will be several new technology pieces added to the puzzle for reasoning, developing and sharing open rule definitions, handling issues around trust, agents, machine learning, ontology development and integration, semantic data storage, retrieval and search, and many other subjects.

Essentially, the Semantic Web enables the gradual transformation of the Web into a database. This is a profound structural change that will touch every layer of Web technology eventually. It will transform database technology, CMS, CRM, enterprise middleware, systems integration, development tools, search engines, groupware, supply-chain integration, and all the other topics that Gartner covers.

The Semantic Web will manifest in several ways. In many cases it will improve applications and services we already use. So for example, we will see semantic
social networks, semantic search, semantic groupware, semantic CMS, semantic CRM, semantic
email, and many other semantic versions of apps we use today. For a specific example, take social networking. We are seeing much talk about "opening  up the social graph" so that social networks are more connected and portable. Ultimately to do this right, the social graph should be represented using Semantic Web standards, so that it truly is not only open but also easily extensible and mashable with other data. 

Web 3.0 is not ONLY the Semantic Web however. Other emerging technologies may play a big role as well. Gartner seems to think Virtual Reality will be one of them. Perhaps, but to be fair, VR is actually a Web 1.0 phenomenon. It’s been around for a long time, and it hasn’t really changed that much. In fact the folks at the MIT Media Lab were working on things that are still far ahead of Second Life, even back in the early 1990’s.

So what other technologies can we expect in Web 3.0 that are actually new? I expect that we will have a big rise in "cloud computing" such as open peer-to-peer grid storage and computing capabilities on the Web — giving any application essentially as much storage and computational power as needed for free or a very low cost. In the mobile arena we will see higher bandwidth, more storage and more powerful processors in mobile devices, as well as powerful built-in speech recognition, GPS and motion sensors enabling new uses to emerge. I think we will also see an increase in the power of personalization tools and personal assistant tools that try to help users manage the complexity of their digital lives. In the search arena, we will see search engines get smarter — among other things they will start to not only answer questions, but they will accept commands such as "find me a cheap flight to NYC" and they will learn and improve as they are used. We will also see big improvements in integration and data and account portability between different Web applications. We will also see a fundamental change in the database world as databases move away from the relational model and object model, towards the associative model of data (graph databases and triplestores).

In short, Web 3.0 is about hard-core new technologies and is going to have a much greater impact on enterprise IT managers and IT systems than Web 2.0. But ironically, it may not be until Web 4.0 (2020 – 2030) that Gartner comes to this conclusion!

Knowledge Networking

I’ve been thinking for several years about Knowledge Networking. It’s not a term I invented, it’s been floating around as a meme for at least a decade or two. But recently it has started to resurface in my own work.

So what is a knowledge network? I define a knowledge network as a form of collective intelligence in which a network of people (two or more people connected by social-communication relationships) creates, organizes, and uses a collective body of knowledge. The key here is that a knowledge network is not merely a site where a group of people work on a body of information together (such as the wikipedia), it’s also a social network — there is an explicit representation of a social relationship within it. So it’s more like a social network than for example a discussion forum or a wiki.

I would go so far as to say that knowledge networks are the third-generation of social software. (Note this is based in-part on ideas that emerged in conversations I have had with Peter Rip, so this also his idea):

  • First-generation social apps were about communication (eg.
    messaging such as Email, discussion boards, chat rooms, and IM)
  • Second-generation social apps were about people and content (eg. Social networks, social media sharing, user-generated content)
  • Third-generation social apps are about relationships and knowledge  (eg. Wikis, referral networks, question and answer systems, social recommendation systems, vertical knowledge and expertise portals, social mashup apps, and coming soon, what we’re building at Radar Networks)

Just some thoughts on a Saturday morning…

Web 3.0 — Next-Step for Web?

The Business 2.0 Article on Radar Networks and the Semantic Web just came online. It’s a huge article. In many ways it’s one of the best popular articles written about the Semantic Web in the mainstream press. It also goes into a lot of detail about what Radar Networks is working on.

One point of clarification, just in case anyone is wondering…

Web 3.0 is not just about machines — it’s actually all about humans — it leverages social networks, folksonomies, communities and social filtering AS WELL AS the Semantic Web, data mining, and artificial intelligence. The combination of the two is more powerful than either one on it’s own. Web 3.0 is Web 2.0 + 1. It’s NOT Web 2.0 – people. The "+ 1" is the
addition of software and metadata that help people and other
applications organize and make better sense of the Web. That new layer
of semantics — often called "The Semantic Web" — will add to and
build on the existing value provided by social networks, folksonomies,
and collaborative filtering that are already on the Web.

So at least here at Radar Networks, we are focusing much of our effort on facilitating people to help them help themselves, and to help each other, make sense of the Web. We leverage the amazing intelligence of the human brain, and we augment that using the Semantic Web, data mining, and artificial intelligence. We really believe that the next generation of collective intelligence is about creating systems of experts not expert systems.

Listen to this Discussion on the Future of the Web

If you are interested in the future of the Web, you might enjoy listening to this interview with me, moderated by Dr. Paul Miller of Talis. We discuss, in-depth: the Semantic Web, Web 3.0, SPARQL, collective intelligence, knowledge management, the future of search, triplestores, and Radar Networks.

Breaking the Collective IQ Barrier — Making Groups Smarter

I’ve been thinking since 1994 about how to get past a fundamental barrier to human social progress, which I call “The Collective IQ Barrier.” Most recently I have been approaching this challenge in the products we are developing at my stealth venture, Radar Networks.

In a nutshell, here is how I define this barrier:

The Collective IQ Barrier: The potential collective intelligence of a human group is exponentially proportional to group size, however in practice the actual collective intelligence that is achieved by a group is inversely proportional to group size. There is a huge delta between potential collective intelligence and actual collective intelligence in practice. In other words, when it comes to collective intelligence, the whole has the potential to be smarter than the sum of its parts, but in practice it is usually dumber.

Why does this barrier exist? Why are groups generally so bad at tapping the full potential of their collective intelligence? Why is it that smaller groups are so much better than large groups at innovation, decision-making, learning, problem solving, implementing solutions, and harnessing collective knowledge and intelligence?

I think the problem is technological, not social, at its core. In this article I will discuss the problem in more depth and then I will discuss why I think the Semantic Web may be the critical enabling technology for breaking through the Collective IQ Barrier.

The Effective Size of Groups

For millions of years — in fact since the dawn of humanity — humansocial organizations have been limited in effective size. Groups aremost effective when they are small, but they have less collectiveknowledge at their disposal. Slightly larger groups optimize both effectiveness and access to resources such as knowledge and expertise. In my own experience working on many different kinds of teams, I think that the sweet-spot is between 20and 50 people. Above this size groups rapidly become inefficient andunproductive.

The Invention of Hierarchy

The solution that humans have used to get around this limitation in the effective size of groups is hierarchy.When organizations grow beyond 50 people we start to break them intosub-organizations of less than 50 people. As a result if you look atany large organization, such as a Fortune 100 corporation, you find ahuge complex hierarchy of nested organizations and cross-functionalorganizations. This hierarchy enables the organization to createspecialized “cells” or “organs” of collective cognition aroundparticular domains (like sales, marketing, engineering, HR, strategy,etc.) that remain effective despite the overall size of theorganization.

By leveraging hierarchy an organization of even hundreds ofthousands of members can still achieve some level of collective IQ as awhole. The problem however is that the collective IQ of the wholeorganization is still quite a bit lower than the combined collectiveIQ’s of the sub-organizations that comprise it. Even in well-structured, well-managed hierarchies, the hierarchy is still less thanthe sum of it’s parts. Hierarchy also has limits — the collective IQof an organization is also inversely proportional to the number ofgroups it contains, and the average number of levels of hierarchybetween those groups (Perhaps this could be defined more elegantly asan inverse function of the average network distance between groups inan organization).

The reason that organizations today still have to make suchextensive use of hierarchy is that our technologies for managingcollaboration, community, knowledge and intelligence on a collectivescale are still extremely primitive. Hierarchy is still one of the only and best solutions we have at our disposal. But we’re getting better fast.

Modern organizations are larger and far more complex than ever would have beenpractical in the Middle Ages, for example. They contain more people,distributed more widely around the globe, with more collaboration andspecialization, and more information, making more rapid decisions, thanwas possible even 100 years ago. This is progress.

Enabling Technologies

There have beenseveral key technologies that made modern organizations possible: the printing press,telegraph, telephone, automobile, airplane, typewriter, radio,television, fax machine, and personal computer. These technologies haveenabled information and materials to flow more rapidly, at less cost,across ever more widely distributed organizations. So we can see that technology does make a big difference in organizational productivity. The question is, can technology get us beyond the Collective IQ Barrier?

The advent of the Internet, and in particular the World Wide Webenabled a big leap forward in collective intelligence. These technologies havefurther reduced the cost to distributing and accessing information andinformation products (and even “machines” in the form of software codeand Web services). They have made it possible for collectiveintelligence to function more rapidly, more dynamically, on a wider scale, and at lesscost, than any previous generation of technology.

As a result of evolution of the Web we have seen new organizationalstructures begin to emerge that are less hierarchical, moredistributed, and often more fluid. For example, virtual teams that caninstantly form, collaborate across boundaries, and then dissolve backinto the Webs they come from when their job is finished. Thisprocess is now much easier than it ever was. Numerous hosted Web-basedtools exist to facilitate this: email, groupware, wikis, messageboards, listservers, weblogs, hosted databases, social networks, searchportals, enterprise portals, etc.

But this is still just the cusp of this trend. Even today with thecurrent generation of Web-based tools available to us, we are still notable to effectively tap much more of the potential Collective IQ of ourgroups, teams and communities. How do we get from where we are today(the whole is dumber than the sum of its parts) to where we want to bein the future (the whole is smarter than the sum of its parts)?

The Future of Productivity

The diagram below illustrates how I think about the past, present and future of productivity. In my view, from the advent of PC’s onwards we have seen a rapid growth in individual and group productivity, enabling people to work with larger sets of information, in larger groups. But this will not last — soon as we reach a critical level of information and groups of ever larger size, productivity will start to decline again, unless new technologies and tools emerge to enable us to cope with these increases in scale and complexity. You can read more about this diagram here.

http://novaspivack.typepad.com/nova_spivacks_weblog/2007/02/steps_towards_a.html

In the last 20 years the amount of information that knowledgeworkers (and even consumers) have to deal with on a daily basis has mushroomed by a factor of almost 10orders of magnitude and it will continue like this for several moredecades. But our information tools — and particular our tools forcommunication, collaboration, community, commerce and knowledgemanagement — have not advanced nearly as quickly. As a result thetools that we are using today to manage our information andinteractions are grossly inadequate for the task at hand: They were simply not designed tohandle the tremendous volumes of distributed information, and the rate of change ofinformation, that we are witnessing today.

Case in point: Email. Email was never designed for what it is beingused for today. Email was a simple interpersonal notification andmessaging tool and essentially that is what it is good for. But todaymost of us use our email as a kind of database, search engine,collaboration tool, knowledge management tool, project management tool,community tool, commerce tool, content distribution tool, etc. Emailwasn’t designed for these functions and it really isn’t very productive whenapplied to them.

For groups the email problem is even worse than it is for individuals –not only is everyone’s individual email productivity declining anyway,but collectively as groupsize increases (and thus group information size increases as well),there is a multiplier effect that further reduces everyone’semail productivity in inverse proportion to the size of the group.Email becomes increasingly unproductive as group size and informationsize increase.

This is not just true of email, however, it’s true of almost all theinformation tools we use today: Search engines, wikis, groupware,social networks, etc. They all suffer from this fundamental problem.Productivity breaks down with scale — and the problem is exponentially worse than it is for individuals in groups and organizations. But scale is increasing incessantly — that is a fact — and it will continue to do so for decades at least. Unless something is done about this we will simply be completely buried in our own information within about a decade.

The Semantic Web

I think the Semantic Web is a critical enabling technology that will help us get through this transition. It willenable the next big leap in productivity and collective intelligence.It may even be the technology that enables humans to flip the ratio so thatfor the first time in human history, larger groups of people canfunction more productively and intelligently than smaller groups. Itall comes down to enabling individuals and groups to maintain (andultimately improve) their productivity in theface of the continuing explosion in information and social complexitythat they areexperiencing.

The Semantic Web provides a richer underlying fabric for expressing,sharing, and connecting information. Essentially it provides a betterway to transform information into useful knowledge, and to share andcollaborate with it. It essentially upgrades the medium — in this case the Web and any other data that is connected to the Web — that we use for our information today.

By enriching the medium we can inturn enable new leaps in how applications, people, groups andorganizations can function. This has happened many times before in thehistory of technology.  The printing press is one example. The Web is a more recent one. The Web enriched themedium (documents) with HTML and a new transport mechanism, HTTP, forsharing it. This brought about one of the largest leaps in humancollective cognition and productivity in history. But HTML really onlydescribes formatting and links. XML came next, to start to provide away to enrich the medium with information about structure –the parts of documents. The Semantic Web takes this one step further –it provides a way to enrich the medium with information about the meaning of the structure — what are those parts, what do various links actually mean?

Essentially the Semantic Web provides a means to abstract andexternalize human knowledge about information — previously the meaningof information lived only in our heads, and perhaps in certainspecially-written software applications that were coded to understandcertain types of data. The Semantic Web will disrupt this situation by providingopen-standards for encoding this meaning right into the medium itself.Any application that can speak the open-standards of the Semantic Webcan then begin to correctly interpret the meaning of information, andtreat it accordingly, without having to be specifically coded tounderstand each type of data it might encounter.

This is analogous to the benefit of HTML. Before HTML everyapplication had to be specifically coded to each different documentformat in order to display it. After HTML applications could all juststandardize on a single way to define the formats of differentdocuments. Suddenly a huge new landscape of information becameaccessible both to applications and to the people who used them.The Semantic Web does something similar: It provides a way to makethe data itself “smarter” so that applications don’t have to know somuch to correctly interpret it. Any data structure — a document or adata record of any kind — that can be marked up with HTML to define its formatting, can also be marked up with RDFand OWL (the languages of the Semantic Web) to define its meaning.

Once semantic metadata is added, the document can not only bedisplayed properly by any application (thanks to HTML and XML), but itcan also be correctly understood by that application. For example theapplication can understand what kind of document it is, what it isabout, what the parts are, how the document relates to other things,and what particular data fields and values mean and how they map todata fields and values in other data records around the Web.

The Semantic Web enriches information with knowledge about what thatinformation means, what it is for, and how it relates to other things.With this in hand applications can go far beyond the limitations ofkeyword search, text processing, and brittle tabular data structures.Applications can start to do a much better job of finding, organizing,filtering, integrating, and making sense of ever larger and morecomplex distributed data sets around the Web.

Another great benefit ofthe Semantic Web is that this additional metadata can be added in atotally distributed fashion. The publisher of a document can add theirown metadata and other parties can then annotate that with their ownmetadata. Even HTML doesn’t enable that level of cooperative markup (exceptperhaps in wikis). It takes a distributed solution to keep up with ahighly distributed problem (the Web). The Semantic Web is just such adistributed solution.

The Semantic Web will enrich information and this in turn will enable people, groups and applications to work with information more productively. In particular groups and organizations will benefit the most because that is where the problems of information overload and complexity are the worst. Individuals at least know how they organize their own information so they can do a reasonably good job of managing their own data. But groups are another story — because people don’t necessarily know how others in their group organize their information. Finding what you need in other people’s information is much harder than finding it in your own.

Where the Semantic Web can help with this is by providing a richer fabric for knowledge management. Information can be connected to an underlying ontology that defines not only the types of information available, but also the meaning and relationships between different tags or subject categories, and even the concepts that occur in the information itself. This makes organizing and finding group knowledge easier. In fact, eventually the hope is that people and groups will not have to organize their information manually anymore — it will happen in an almost fully-automatic fashion. The Semantic Web provides the necessary frameworks for making this possible.

But even with the Semantic Web in place and widely adopted, moreinnovation on top of it will be necessary before we can truly breakpast the Collective IQ Barrier such that organizations can in practiceachieve exponential increases in Collective IQ. Human beings are only able to cope with a few chunks ofinformation at a given moment, and our memories and ability to processcomplex data sets are limited. When group size and data size growbeyond certain limits, we simply cannot cope, we become overloaded andjammed, even with rich Semantic Web content at our disposal.

Social Filtering and Social Networking — Collective Cognition

Ultimately, to remain productive in the face of such complexity wewill need help. Often humans in roles that require them to cope with large scales of information, relationships andcomplexity hire assistants, but not all of us can affordto do that, and in some cases even assistants are not able to keep upwith the complexity that has to be managed.

Social networking andsocial filtering are two ways to expand the number of “assistants” weeach have access to, while also reducing the price of harnessing the collective intelligence of those assistants to just about nothing. Essentially these methodologies enable people toleverage the combined intelligence and attention of large communitiesof like-minded people who contribute their knowledge and expertise for free. It’s a collective tit-for-tat form of altruism.

For example, Diggis a community that discovers the most interesting news articles. Itdoes this by enabling thousands of people to submit articles and voteon them. What Digg adds are a few clever algorithms on top of this for rankingarticles such that the most active ones bubble up to the top. It’s notunlike a stock market trader’s terminal, but for a completely differentclass of data. This is a great example of social filtering.

Anothergood example are prediction markets, where groups of people vote onwhat stock or movie or politician is likely to win — in some cases bybuying virtual stock in them — as a means to predict the future. Ithas been shown that prediction markets do a pretty good job of makingaccurate predictions in fact. In addition expertise referral serviceshelp people get answers to questions from communities of experts. Theseservices have been around in one form or another for decades and haverecently come back into vogue with services like Yahoo Answers. Amazonhas also taken a stab at this with their Amazon Mechanical Turk, whichenables “programs” to be constructed in which people perform the work.

I think social networking, social filtering, prediction markets,expertise referral networks, and collective collaboration are extremelyvaluable. By leveraging other people individuals and groups can stayahead of complexity and can also get the benefit of wide-areacollective cognition. These approaches to collective cognition arebeginning to filter into the processes of organizations and othercommunities. For example, there is recent interest in applying socialnetworking to niche communities and even enterprises.

The Semantic Webwill enrich all of these activities — making social networks andsocial filtering more productive. It’s not an either/or choice — thesetechnologies are extremely compatible in fact. By leveraging acommunity to tag, classify and organize content, for example, themeaning of that content can be collectively enriched. This is alreadyhappening in a primitive way in many social media services. TheSemantic Web will simply provide a richer framework for doing this.

The combination of the Semantic Web with emerging social networkingand social filtering will enable something greater than either on it’sown. Together, together these two technologies will enable much smarter groups, social networks, communities and organizations. But this still will not get us all the way past the Collective IQBarrier. It may get us close the threshold though. To cross thethreshold we will need to enable an even more powerful form ofcollective cognition.

The Agent Web

To cope with the enormous future scale andcomplexity of the Web, desktop and enterprise, each individual and group willreally need not just a single assistant, or even a community of humanassistants working on common information (a social filtering communityfor example), they will need thousands or millions of assistants working specificallyfor them. This really only becomes affordable and feasible if we canvirtualize what an “assistant” is.

Human assistants are at the top ofthe intelligence pyramid — they are extremely smart and powerful, and they are expensive — they  should not beused for simple tasks like sorting content, that’s just a waste oftheir capabilities. It would be like using a supercomputer array tospellcheck a document. Instead, we need to free humans up to do thereally high-value information tasks, and find a way to farm out thelow-value, rote tasks to software. Software is cheap or even free and it can be replicated as much asneeded in order to parallelize. A virtual army of intelligent agents is less expensive than a single human assistant, and much more suited to sifting through millions of Web pages every day.

But where will these future intelligent agents get their intelligence? In past attempts at artificial intelligence, researchers tried to buildgigantic expert systems that could reason as well as a small child forexample. These attempts met with varying degrees of success, but theyall had one thing in common: They were monolithic applications.

I believe that that future intelligent agents should be simple. They should not be advanced AI programs or expert systems. They should be capable of a few simple behaviors, the most important of which is to reason against sets of rules and semantic data. The basic logic necessary for reasoning is not enormous and does not require any AI — it’s just the ability to follow logical rules and perhaps do set operations. They should be lightweight and highly mobile. Insteadof vast monolithic AI, I am talking about vast numbers of very simpleagents that working together can do  emergent, intelligent operations en masse.

For example search — you might deploy a thousand agents to search all the sites about Italy for recipes and then assemble those results into a database instantaneously.  Or you might dispatch a thousand or more agents to watch for a job that matches your skills and goals across hundreds of thousands or millions of Websites. They could watch and wait until jobs that matched your criteria appeared, and then they could negotiate amongst themselves to determine which of the possible jobs they found were good enough to show you. Another scenario might be commerce — you could dispatch agents to find you the best deal on a vacation package, and they could even negotiate an optimal itinerary and price for you. All you would have to do is choose between a few finalist vacation packages and make the payment. This could be a big timesaver.

The above examples illustrate how agents might help an individual, but how might they help a group or organization? Well for one thing agents could continuously organize and re-organize information for a group. They could also broker social interactions — for example, by connecting people to other people with matching needs or interests, or by helping people find experts who could answer their questions. One of the biggest obstacles to getting past the Collective IQ Barrier is simply that people cannot keep track of more than a few social relationships and information sources at aany given time — but with an army of agents helping them, individuals might be able to cope with more relationships and data sources at once; the agents would act as their filters, deciding what to let through and how much priority to give it. Agents can also help to make recommendations, and to learn to facilitate and even automate various processes such as finding a time to meet, or polling to make a decision, or escalating an issue up or down the chain of command until it is resolved.

To make intelligent agents useful, they will need access to domain expertise. But the agents themselves will not contain any knowledge or intelligence of their own. The knowledge will exist outside on the Semantic Web, and so will the intelligence. Their intelligence, like their knowledge, will be externalized and virtualized in the form of axioms or rules that will exist out on the Web just like web pages.

For example, a set of axioms about travel could be published to the Web in the form of a document that formally defined them. Any agent that needed to process travel-related content could reference these axioms in order to reason intelligently about travel in the same way that it might reference an ontology about travel in order to interpret travel data structures. The application would not have to be specifically coded to know about travel — it could be a generic simple agent — but whenever it encountered travel-related content it could call up the axioms about travel from the location on the Web where they were hosted, and suddenly it could reason like an expert travel agent. What’s great about this is that simple generic agents would be able to call up domain expertise on an as-needed basis for just about any domain they might encounter. Intelligence — the heuristics, algorithms and axioms that comprise expertise, would be as accessible as knowledge — the data and connections between ideas and information on the Web.

The axioms themselves would be created by human experts in various domains, and in some cases they might even be created or modified by agents as they learned from experience. These axioms might be provided for free as a public service, or as fee-based web-services via API’s that only paying agents could access.

The key is that model is extremely scaleable — millions or billions of axioms could be created, maintained, hosted, accessed, and evolved in a totally decentralized and parallel manner by thousands or even hundreds of thousands of experts all around the Web. Instead of a few monolithic expert systems, the Web as a whole would become a giant distributed system of experts. There might be varying degrees of quality among competing axiom-sets available for any particular domain, and perhaps a ratings system could help to filter them over time. Perhaps a sort of natural selection of axioms might take place as humans and applications rated the end-results of reasoning using particular sets of axioms, and then fed these ratings back to the sources of this expertise, causing them to get more or less attention from other agents in the future. This process would be quite similar to the human-level forces of intellectual natural-selection at work in fields of study where peer-review and competition help to filter and rank ideas and their proponents.

Virtualizing Intelligence

What I have been describing is the virtualization of intelligence — making intelligence and expertise something that can be “published” to the Web and shared just like knowledge, just like an ontology, a document, a database, or a Web page. This is one of the long-term goals of the Semantic Web and it’s already starting now via new languages, such as SWRL, that are being proposed for defining and publishing axioms or rules to the Web. For example, “a non-biologicalparent of a person is their step-parent” is asimple axiom. Another axiom might be, “A child of a sibling of your parent is your cousin.” Using such axioms, an agent could make inferences and do simple reasoning about social relationships for example.

SWRL and other proposed rules languages provide potentialopen-standards for defining rules and publishing them to the Web sothat other applications can use them. By combining these rules withrich semantic data, applications can start to do intelligent things,without actually containing any of the intelligence themselves. The intelligence– the rules and data — can live “out there” on the Web, outside the code of various applications.

All theapplications have to know how to do is find relevant rules, interpret them, and apply them. Even the reasoning that may be necessary can be virtualized into remotely accessible Web services so applications don’t even have to do that part themselves (although many may simply include open-source reasoners in the same way that they include open-source databases or search engines today).

In other words, just as HTML enables any app to process and formatany document on the Web, SWRL + RDF/OWL may someday enable any application to reasonabout what the document discusses. Reasoning is the last frontier. Byvirtualizing reasoning — the axioms that experts use to reason aboutdomains — we can really begin to store the building blocks of humanintelligence and expertise on the Web in a universally-accessibleformat. This to me is when the actual “Intelligent Web” (what I callWeb 4.0) will emerge.

The value of this for groups and organizations is that they can start to distill their intelligence from individuals that comprise them into a more permanent and openly accessible form — axioms that live on the Web and can be accessed by everyone. For example, a technical support team for a product learns many facts and procedures related to their product over time. Currently this learning is stored as knowledge in some kind of tech support knowledgebase. But the expertise for how to find and apply this knowledge still resides mainly in the brains of the people who comprise the team itself.

The Semantic Web provides ways to enrich the knowledgebase as well as to start representing and saving the expertise that the people themselves hold in their heads, in the form of sets of axioms and procedures. By storing not just the knowledge but also the expertise about the product, the humans on the team don’t have to work as hard to solve problems — agents can actually start to reason about problems and suggest solutions based on past learning embodied in the common set of axioms. Of course this is easier said than done — but the technology at least exists in nascent form today. In a decade or more it will start to be practical to apply it.

Group Minds

Someday in the not-too-distant-future groups will be able toleverage hundreds or thousands of simple intelligent agents. Theseagents will work for them 24/7 to scour the Web, the desktop, theenterprise, and other services and social networks they are related to. They will help both the individuals as well as the collectives as-a-whole. They willbe our virtual digital assistants, always alert and looking for thingsthat matter to us, finding patterns, learning on our behalf, reasoningintelligently, organizing our information, and then filtering it,visualizing it, summarizing it, and making recommendations to us sothat we can see the Big Picture, drill in wherever we wish, and makedecisions more productively.

Essentially these agents will give groups something like their own brains. Today the only brains in a group reside in the skulls of the people themselves. But in the future perhaps we will see these technologies enable groups to evolve their own meta-level intelligences: systems of agents reasoning on group expertise and knowledge.

This will be a fundamental leap to a new order of collective intelligence. For the first time groups will literally have minds of their own, minds that transcend the mere sum of the individual human minds that comprise their human, living facets. I call these systems “Group Minds” and I think they are definitely coming. In fact there has been quite a bit of research on the subject of facilitating group collaboration with agents, for example, in government agencies such as DARPA and the military, where finding ways to help groups think more intelligently is often a matter of life and death.

The big win from a future in which individuals and groups canleverage large communities of intelligent agents is that they will bebetter able to keep up with the explosive growth of information complexity andsocial complexity. As the saying goes, “it takes a village.” There is just too much information, and too many relationships, changing too fast and this is only going to get more intense in years to come. The only way to cope with such a distributed problem is a distributed solution.

Perhaps by 2030 it will not be uncommon for Individuals and groups to maintain largenumbers of virtual assistants — agents that will help them keep abreast of themassively distributed, always growing and shifting information and sociallandscapes. When you really think about this, how else could we eversolve this? This is really the only practical long-term solution. But today it is still a bit of a pipedream; we’re not there yet. The key however is that we are closer than we’ve ever been before.

Conclusions

The Semantic Web provides the key enabling technology for all ofthis to happen someday in the future. By enriching the content of theWeb it first paves the way to a generation of smarter applications andmore productive individuals, groups and organizations.

The next majorleap will be when we begin to virtualize reasoning in the form ofaxioms that become part of the Semantic Web. This will enable a newgeneration of applications that can reason across information andservices. This will ultimately lead to intelligent agents that will be able to assist individuals,groups, social networks, communities, organizations and marketplaces sothat they can remain productive in the fact of the astonishinginformation and social network complexity in our future.

By adding more knowledge into our information, the Semantic Webmakes it possible for applications (and people) to use information moreproductively. By adding more intelligence between people,  information,and applications, the Semantic Web will also enable people andapplications to become smarter. In the future, these more-intelligentapps will facilitate higher levels of individual and collectivecognition by functioning as virtual intelligent assistants forindividuals and groups (as well as for online services).

Once we begin to virtualize not just knowledge (semantics) but alsointelligence (axioms) we will start to build Group Minds — groups that have primitive minds of their own. When we reach this point we will finally enable organizations to breakpast the Collective IQ Barrier: Organizations will start to becomesmarter than the sum of their parts. The intelligence of anorganization will not just be from its people, it will also come fromits applications. The number of intelligent applications in anorganization may outnumber the people by 1000 to 1, effectivelyamplifying each individual’s intelligence as well as the collectiveintelligence of the group.

Because software agents work all the time,can self-replicate when necessary, and are extremely fast and precise,they are ideally-suited to sifting in parallel through the millions or billions ofdata records on the Web, day in and day out. Humans and even groups ofhumans will never be able to do this as well. And that’s not what theyshould be doing! They are far too intelligent for that kind of work.Humans should be at the top of the pyramid, making the decisions,innovating, learning, and navigating.

When we finally reach this stage where networks of humans and smartapplications are able to work together intelligently for common goals,I believe we will witness a real change in the way organizations arestructured. In Group Minds, hierarchy will not be as necessary — the maximum effectivesize of a human Group Mind will be perhaps in the thousands or even themillions instead of around 50 people. As a result the shape of organizations in thefuture will be extremely fluid, and most organizations will be flat orcontinually shifting networks. For more on this kind of organization,read about virtual teams and networking, such as these books (by friends of mine who taught me everything I know about network-organization paradigms.)

I would also like to note that I am not proposing “strong AI” — a vision in which we someday makeartificial intelligences that are as or more intelligent thanindividual humans. I don’t think intelligent agents will individually be very intelligent. It will only be in vast communities of agents that intelligence will start to emerge. Agents are analogous to the neurons in the human brain — they really aren’t very powerful on their own.

I’m also not proposing that Group Minds will beas or more intelligent as the individual humans in groups anytime soon. I don’t think thatis likely in our lifetimes. The cognitive capabilities of an adult human are the product of millions of years of evolution. Even in the accelerated medium of the Web where evolution can take place much faster in silico, it may still take decades or even centuries to evolve AI that rivals the human mind (and I doubt such AI will ever be truly conscious, which means that humans, with their inborn natural consciousness, may always play a special and exclusive role in the world to come, but that is the subject of a different essay). But even if they will not be as intelligent as individual humans, Ido think that Group Minds, facilitated by masses of slightly intelligent agents and humans working in concert, can goa long way in helping individuals and groups become more productive.

It’s important to note that the future I am describing is notscience-fiction, but it also will not happen overnight. It will take atleast several decades, if not longer. But with the seeminglyexponential rate of change of innovation, we may make very large stepsin this direction very soon. It is going to be an exciting lifetime forall of us.

Diagram: Beyond Keyword (and Natural Language) Search

Here at Radar Networks we are working on practical ways to bring the Semantic Web to end-users. One of the interesting themes that has come up a lot, both internally, as well as in discussions with VC’s, is the coming plateau in the productivity of keyword search. As the Web gets increasingly large and complex, keyword search becomes less effective as a means for making sense of it. In fact, it will even decline in productivity in the future. Natural language search will be a bit better than keyword search, but ultimately won’t solve the problem either — because like keyword search it cannot really see or make use of the structure of information.

I’ve put together a new diagram showing how the Semantic Web will enable the next step-function in productivity on the Web. It’s still a work in progress and may change frequently for a bit, so if you want to blog it, please link to this post, or at least the .JPG image behind the thumbnail below so that people get the latest image. As always your comments are appreciated. (Click the thumbnail below for a larger version).

Futureofproductivity_2

Today a typical Google search returns up to hundreds of thousands or even millions of results — but we only really look at the first page or two of results. What about the other results we don’t look at? There is a lot of room to improve the productivity of search, and the help people deal with increasingly large collections of information.

Keyword search doesn’t understand the meaning of information, let alone its structure. Natural language search is a little better at understanding the meaning of information — but it still won’t help with the structure of information. To really improve productivity significantly as the Web scales, we will need forms of search that are data-structure-aware — that are able to search within and across data structures, not just unstructured text or semistructured HTML. This is one of the key benefits of the coming Semantic Web: it will enable the Web to be navigated and searched just like a database.

Starting with the "data web" enabled by RDF, OWL, ontologies and SPARQL, structured data is becoming increasingly accessible, searchable and mashable. This in turn sets the stage for a better form of search: semantic search. Semantic search combines the best of keyword, natural language, database and associative search capabilities together.

Without the Semantic Web, productivity will plateau and then gradually decline as the Web, desktop and enterprise continue to grow in size and complexity. I believe that with the appropriate combination of technology and user-experience we can flip this around so that productivity actually increases as the size and complexity of the Web increase.

Envisioning the Whole Digital Person

Another article of note on the subject of our evolving digital lives and what user-experience designers should be thinking about:

Our lives are becoming increasingly digitized—from the ways we
communicate, to our entertainment media, to our e-commerce
transactions, to our online research. As storage becomes cheaper and
data pipes become faster, we are doing more and more online—and in the
process, saving a record of our digital lives, whether we like it or
not.

(snip…)

In the coming years, our ability to interact with the information
we’re so rapidly generating will determine how successfully we can
manage our digital lives. There is a great challenge at our doorsteps—a
shift in the way we live with each other.

As designers of user experiences for digital products
and services, we can make people’s digital lives more meaningful and
less confusing. It is our responsibility to envision not only
techniques for sorting, ordering, and navigating these digital
information spaces, but also to devise methods of helping people feel
comfortable with such interactions. To better understand and ultimately
solve this information management problem, we should take a holistic
view of the digital person. While our data might be scattered, people
need to feel whole.

Web 3.0 Roundup: Radar Networks, Powerset, Metaweb and Others…

It’s been a while since I posted about what my stealth venture, Radar Networks, is working on. Lately I’ve been seeing growing buzz in the industry around the "semantics" meme — for example at the recent DEMO conference, several companies used the word "semantics" in their pitches. And of course there have been some fundings in this area in the last year, including Radar Networks and other companies.

Clearly the "semantic" sector is starting to heat up. As a result, I’ve been getting a lot of questions from reporters and VC’s about how what we are doing compares to other companies such as for example, Powerset, Textdigger, and Metaweb. There was even a rumor that we had already closed our series B round! (That rumor is not true; in fact the round hasn’t started yet, although I am getting very strong VC interest and we will start the round pretty soon).

In light of all this I thought it might be helpful to clarify what we are doing, how we understand what other leading players in this space are doing, and how we look at this sector.

Indexing the Decades of the Web

First of all, before we get started, there is one thing to clear up. The Semantic Web is part of what is being called "Web 3.0" by some, but it is in my opinion really just one of several converging technologies and trends that will define this coming era of the Web. I’ve written here about a proposed definition of Web 3.0, in more detail.

For those of you who don’t like terms like Web 2.0, and Web 3.0, I also want to mention that  I agree — we all want to avoid a rapid series of such labels or an arms-race of companies claiming to be > x.0. So I have a practical proposal: Let’s use these terms to index decades since the Web began. This is objective — we can all agree on when decades begin and end, and if we look at history each decade is characterized by various trends. 

I think this is reasonable proposal and actually useful (and also avoids endless new x.0’s being announced every year). Web 1.0 was therefore the first decade of the Web: 1990 – 2000. Web 2.0 is the second decade, 2000 – 2010. Web 3.0 is the coming third decade, 2010 – 2020 and so on. Each of these decades is (or will be) characterized by particular technology movements, themes and trends, and these indices, 1.0, 2.0, etc. are just a convenient way of referencing them. This is a useful way to discuss history, and it’s not without precedent. For example, various dynasties and historical periods are also given names and this provides shorthand way of referring to those periods and their unique flavors. To see my timeline of these decades, click here.

So with that said, what is Radar Networks actually working on? First of all, Radar Networks is still in stealth, although we are
planning to go beta in 2007. Until we get closer to launch what I can
say without an NDA is still limited. But at least I can give some
helpful hints for those who are interested. This article provides some hints, as well as what I hope is a helpful tutorial about natural language search and the Semantic Web, and how they differ. I’ll also discuss how Radar Networks compares some of the key startup ventures working with semantics in various ways today (there are many other companies in this sector — if you know of any interesting ones, please let me know in the comments; I’m starting to compile a list).

The Semantic Web is About Helping People Use the Web More Productively

I’ve been reading some of the further posts on various blogs in reaction to the Markoff article in the New York Times last Sunday. There is a tremendous amount of misconception about the Semantic Web– as evidenced for example by Ross Mayfield’s post recently. Ross implied that the Semantic Web is about automating the Web, rather than facilitating people. This is a misconception that others have taken to even further extremes — some people have characterized it as an effort to replace humans, replace social networks and social software, etc. etc. That is simply NOT at all correct! Quite the opposite in fact.

The Semantic Web is just a way to augment and improve the EXISTING Web and all the existing relationships, groups, communities, social networks, user-experiences, apps, content, and online services on it. It doesn’t replace the Web we have, it just makes it smarter. It doesn’t replace human intelligence and decision-making, it just augments human thinking, so that individuals and groups can overcome the growing complexity of information overload on the Web.

Extremely Cool — Sony Invention Links Digital and Physical World

This is an extremely cool video of a beautifully designed interface that connects physical objects and digital objects in a new way. You can drag things off of your computer, right onto your table, and then from there connect them to physical objects, like a book, which can then be moved around causing the digital objects they are linked with to also move. You have to see it to understand. Watch the video. Love it.
