    What is the Semantic Web?
  • 9. The Semantic Web in essence
    • The word “semantic” stands for “the meaning of”:
      • The Beatles were a popular band from Liverpool; Lennon was a member of the Beatles; "Hey Jude" was recorded by the Beatles
    • The Semantic Web is a Web that is able to describe things in a way that computers can understand
  • 10. What is Web 2.0?
    • The term Web 2.0 was made popular by Tim O’Reilly:
      • http://www.oreillynet.com/pub/a/oreilly/tim/news/2005/09/30/what-is-web-20.html
    • http://en.wikipedia.org/wiki/Web_2.0
      • “ Web 2.0 … has … come to refer to what some people describe as a second phase of architecture and application development for the World Wide Web.”
    • The Web where “ordinary” users can meet, collaborate, and share using social software applications on the Web (tagged content, social bookmarking, AJAX, etc.)
    • Popular examples include:
      • Bebo, del.icio.us, digg, Flickr, Google Maps, Skype, Technorati, orkut, 43 Things, Wikipedia…

      • Reusable community contributions
      • Subscriptions to information, news, data flows, services
      • Mass-publishing using web-based social software
    • http://en.wikipedia.org/wiki/Social_Software
      • “ Social Software lets people rendezvous, connect or collaborate by use of a computer network. It results in the creation of shared, interactive spaces…”
    • Social software for communication and collaboration:
      • IM, IRC, Forums, Blogs, Wikis, Social Network Services, Social Bookmarks, Podcasts, MMOGs…

  • 21. What are tagging and folksonomies?
    • Tag:
      • A keyword which acts like a subject or category
    • Folksonomy:
      • A collaboratively generated, open-ended labeling system that enables Internet users to categorise content using tags:
        • Web links and pages (e.g. del.icio.us) using “social bookmarking”
        • Online photographs (e.g. Flickr, Zooomr)
        • Events (e.g. Upcoming.org)
        • Blog entries, etc.
    • Tag cloud:
      • A visual depiction of the tags used on a website:
        • Equivalent to a weighted list in the field of visual design
  • 22.

  • 23. The path to Web 3.0 (the Semantic Web)
    • The Semantic Web effort is mainly towards producing standards and recommendations that will interlink applications
    • The Web 2.0 meme is about providing user applications
    • Not mutually exclusive:
      • http://www.oreillynet.com/xml/blog/2005/10/is_web_20_killing_the_semantic.html
      • With a little effort, many Web 2.0 applications can and do use Semantic Web technologies to great benefit
      • We will now discuss Web 2.0 and describe what happens when we combine it with the Semantic Web
