  • Despite these individual contributions (which we will revisit in more detail in Section 2), to fully understand tagging systems we believe a holistic approach is necessary. Walker [24] describes tagging as “feral hypertext”, a structure out of control, where the same tag is assigned to different resources with different semantic senses, and thus associates otherwise unrelated resources. However, by considering the entire model, computer systems could make inferences that “domesticate” (to use Walker’s terms) these “feral” tags. For example, tag semantics and synonyms could potentially be inferred by analyzing the structure of the social network, and identifying certain portions of the network that use certain tags for the same resource, or related resources, interchangeably. These tags may be synonymous
  • Different designs and user incentives can have a major influence on the usefulness of information for various purposes and applications, and in a reciprocal fashion, on how users appropriate and utilize these systems. The design of the system may solicit tagging useful for discovery, retrieval, remembrance, social interaction, or possibly, all of the above
  • Other likely explanations for the observed correlation between social connection and common tag usage may be found in the descriptive categories of sociolinguistics which studies how different geographic and social formations structure the coherence and diffusion of semantic and syntactic structures in various ”lects” within a larger sociolinguistic system. Some of these example lects include: dialect (a lect used by a geographicallydefined community); sociolect (a lect used by a socially defined community); ethnolect (a lect spoken by a particular ethnic group); ecolect (a lect spoken within a household or family); and idiolect (a lect particular to a certain person). If we conceptualize social tagging systems within the theoretical frame of sociolinguistics, these and other “lects” seem especially applicable to understanding and classifying the apparent isomorphism between social and linguistic structures we observed in Flickr. The structures, changes, and diffusion within and amongst various “lects” in social tagging systems will likely have similar patterns to those found in social network analyses and in sociolinguistic language maps.

Collective Knowledge Systems: Where the Social Web meets the Semantic Web - 1 views

  • Collective Knowledge Systems: Where the Social Web meets the Semantic Web
  • What can happen if we combine the best ideas from the Social Web and Semantic Web?
  • The Vision of Collective Intelligence
  • ...20 more annotations...
  • The Social Web is represented by a class of web sites and applications in which user participation is the primary driver of value.
  • Collective intelligence is a grand vision, one to which I subscribe.  However, I would call the current state of the Social Web something else: collected intelligence.   That is, the value of these user contributions is in their being collected together and aggregated into community- or domain-specific sites
  • The grand challenge is to boost the collective IQ of organizations and of society
  • With the rise of the Social Web, we now have millions of humans offering their knowledge online, which means that the information is stored, searchable, and easily shared.  The challenge for the next generation of the Social and Semantic Webs is to find the right match between what is put online and methods for doing useful reasoning with the data.  True collective intelligence can emerge if the data collected from all those people is aggregated and recombined to create new knowledge and new ways of learning that individual humans cannot do by themselves.
  • Technology can augment the discovery and creation of knowledge. For instance, some drug discovery approaches embody a system for learning from models and data that are extracted from published papers and associated datasets.  By assembling large databases of known entities relevant to human biology, researchers can run computations that generate and test hypotheses about possible new therapeutic agents.
  • The first approach is to expose the structured data that already underlies the unstructured web pages.  An obvious technique is for the site builder, who is generating unstructured web pages from a database, to expose the structured data in those pages using standard formats.
  • the second approach, to extract structured data from unstructured user contributions [2] [28] [39] .  It is possible to do a reasonable job at identifying people, companies, and other entities with proper names, products, instances of relations you are interested in (e.g., person joining a company) [1] [7] , or instances of questions being asked [24] . There also techniques for pulling out candidates to use as classes and relations, although these are a bit noisier than the directed pattern matching algorithms [8] [23]  [31] [32] [36] [38] [42]
  • Tomorrow, the web will be understood as an active human-computer system, and we will learn by telling it what we are interested in, asking it what we collectively know, and using it to apply our collective knowledge to address our collective needs.
  • The third approach is to capture structured data on the way into the system.  The straightforward technique is to give users tools for structuring their data, such as ways of adding structured fields and making class hierarchies.
  • In a sense, the TagCommons project is attempting to create a platform for interoperability of social web data on the Semantic Web that is akin to the "mash-up" ecology that is celebrated in Web 2.0.
  • An example of how a system might apply some of these ideas is RealTravel.  RealTravel is an example of "Web 2.0 for travel".  It attracts travelers to share their experiences: sharing their itineraries, stories, photographs, where they stayed, what they did, and their recommendations for fellow travelers.  Writers think of RealTravel as a great platform to share their experiences -- a blog site that caters to this domain.  People who are planning travel use the site as a source of information to research their trip,
  • The collection of tags for a site is called the folksonomy, which is useful data about collective interests.
  • like many Web 2.0 sites, combines these structured dimensions to order the unstructured content.  For example, one can find all the travel blogs about diving, sorted by rating.  In fact, the site combines all of the structured dimensions into a matrix, which offers the user a way to "pivot browse" along any dimension from any point in the matrix.
  • This paper argues that the Social Web and the Semantic Web should be combined, and that collective knowledge systems are the "killer applications" of this integration.  The keys to getting the most from collective knowledge systems, toward true collective intelligence, are tightly integrating user-contributed content and machine-gathered data, and harvesting the knowledge from this combination of unstructured and structured information.
  • Structured and unstructured, formal and informal -- these are not new dimensions.  They are typically considered poles of a continuum.
  • We are beginning to see companies launching services under the banner of Web 3.0 [25] that aim explicitly at collective intelligence.  For instance, MetaWeb [35] is collecting a commons of integrated, structured data in a social web manner, and Radar Networks [25] is applying semantic web technologies to enrich the applications and data of the social web.
  • The other major area where Semantic Web can help achieve the vision of collective intelligence is in the area of interoperability.  If the world's knowledge is to be found on the Web, then we should be able to use it to answer questions, retrieve facts, solve problems, and explore possibilities.

The New Atlantis » Virtual Friendship and the New Narcissism - 0 views

  • or centuries, the rich and the powerful documented their existence and their status through painted portraits.
  • Self-portraits can be especially instructive. By showing the artist both as he sees his true self and as he wishes to be seen, self-portraits can at once expose and obscure, clarify and distort.
  • Today, our self-portraits are democratic and digital; they are crafted from pixels rather than paints. On social networking websites like MySpace and Facebook, our modern self-portraits feature background music, carefully manipulated photographs, stream-of-consciousness musings, and lists of our hobbies and friends.
  • ...13 more annotations...
  • A new generation of social networking websites appeared in 2002 with the launch of Friendster, whose founder,
  • Friendster was an immediate success, with millions of registered users by mid-2003.
  • MySpace, launched in 2003, quickly to surpass it.
  • Besides MySpace and Friendster, the best-known social networking site is Facebook, launched in 2004.
  • Niche social networking sites are also flourishing:
  • Other niche social networking sites connect like-minded self-improvers;
  • 43things.com
  • Social networking sites are also fertile ground for those who make it their lives’ work to get your attention—namely, spammers, marketers, and politicians.
  • . On MySpace and Facebook, for example, the process of setting up one’s online identity is relatively simple:
  • By contrast, Facebook limits what its users can do to their profiles. Besides general personal information, Facebook users have a “Wall” where people can leave them brief notes, as well as a Messages feature that functions like an in-house Facebook e-mail account. You list your friends on Facebook as well, but in general, unlike MySpace friends, which are often complete strangers (or spammers) Facebook friends tend to be part of one’s offline social circle.
  • Social networking websites “connect” users with a network—literally, a computer network. But the verb to network has long been used to describe an act of intentional social connecting, especially for professionals seeking career-boosting contacts. When the word first came into circulation in the 1970s, computer networks were rare and mysterious. Back then, “network” usually referred to television. But social scientists were already using the notion of networks and nodes to map out human relations and calculate just how closely we are connected.
  • There is a Spanish proverb that warns, “Life without a friend is death without a witness.” In the world of online social networking, the warning might be simpler: “Life without hundreds of online ‘friends’ is virtual death.” On these sites, friendship is the stated raison d’être. “A place for friends,” is the slogan of MySpace. Facebook is a “social utility that connects people with friends.” Orkut describes itself as “an online community that connects people through a network of trusted friends.” Friendster’s name speaks for itself.
  • But “friendship” in these virtual spaces is thoroughly different from real-world friendship.

  • Frequently referred to as crowdsourcing, and a darling of the Web 2.0 industry, it has recently come of age as the tools and marketplaces for on-demand work capacity on the network have expanded far beyond the early volunteer communities that originally proved out the concepts. These pioneers, which include the world of open source software and online services such as YouTube and Threadless, get most of their value from a large group of people or community through the simple use of an open invitation.
  • The reasons that a business would use crowdsourcing is varied. They include ability to offload peak demand, access to cheaper business inputs, generating better results, and tackling problems that would have been too difficult to do otherwise.

  • Yet we are trained to hold copyright as a natural right. People who infringe on copyright are labelled as pirates, thieves. We are told that they literally steal from hard-working creators.
  • Fourth myth: We know that copyright makes us collectively better off. The evidence points in the opposite direction. Germany had weak copyright laws up until the Copyright Act of 1901. Yet, maybe because of these weak laws, it became a literary and scientific power: (…), only 1,000 new works appeared annually in England at that time – 10 times fewer than in Germany – and this was not without consequences. Höffner believes it was the chronically weak book market that caused England, the colonial power, to fritter away its head start within the span of a century, while the underdeveloped agrarian state of Germany caught up rapidly, becoming an equally developed industrial nation by 1900.
