  1. Ontologies, Web 2.0 and Beyond Tom GruberTagCommons.orgtomgruber.org

  2. Doug Engelbart, 1968 "The grand challenge is to boost the collective IQ of organizations and of society. "

  3. Tim Berners-Lee, 2001 “The Semantic Web is not a separate Web but an extension of the current one, in which information is given well-defined meaning, better enabling computers and people to work in cooperation.” NY Times, Nov 2, 2006

  4. Tim O’Reilly, 2006, on Web 2.0 "The central principle behind the success of the giants born in the Web 1.0 era who have survived to lead the Web 2.0 era appears to be this, that they have embraced the power of the web to harness collective intelligence"

  5. Web 2.0 is about The Social Web • 1 billion people connect to the Internet • 100 million web sites • over a third of adults in US have contributed content to the public Internet. - 18% of adults over 65 source: Pew Internet and American Life Project via futureexpolporation.net diagram source: http://web2.wsj2.com/

  8. capturing everything storing everything distributing everything many-to-many communication creating value from the data PCs, cameras, mobile phones databases and cheap storage Internet and Web Internet, Email, and collaboration software Web 1.0: ecommerce, search Web 2.0: social software Web 3.0: Semantic Web Roles for Technology

  9. Killer App for Web 3.0:“Collective Knowledge” Systems • provide useful information • based on human contributions • augmented with structured data • from multiple, heterogeneous sources • integrated meaningfully • which gets better as more people participate.
