A talk given at CSHALS 2010, an overview of the current state of linked data, Semantic Web, and Web 3.0 efforts.

1. Web 3.0 emerges… Jim Hendler Tetherless World Professor of Computer and Cognitive Science Assistant Dean of Information Technology and Web Science Rensselaer Polytechnic Institute http://www.cs.rpi.edu/~hendler

3. The Semantic Web (ca. 2001) (Berners-Lee, Hendler, Lassila; 2001)

12. cf. Yahoo mixes RDF with other technologies: at Web scale Dave Beckett, SemTech 08 http://www.semantic-conference.com/session/733/

14. The data is out there Example: the linked open data cloud now has tens of billions of triples and is growing rapidly

15. Government Data on the Web

18. Adding Meta-data

19. Pump through to Google Viz for demos

20. Data.gov + epa.gov

21. Adding some Web magic Web Analytics Social Data Networks External Links

22. Mashup w/Web content

23. Linked Data (RDF, SPARQL) Semantic Web (RDFS, owl) Web 3.0 Web 2.0 Web 3.0 extends current Web applications using Semantic Web technologies and graph-based, open data.

24. Semantic Search IEEE Computer, Jan 2010; IEEE Computing Now, Feb 2010 (free)

25. Semantic Search examples T2 (twine.com) TipTop ( feeltiptop.com )

26. Web 3.0 examples Semantic classified (bintro.com)

27. Trialx.com

28. Web 3.0 examples

29. Web 3.0 examples Social database (freebase.com)

30. Tiptop health Ok, so we have a way to go on this one 

32. 1B computers (mostly owned by a few large companies) 3B cell phones (most are Web enable)

33. Sem Web going mobile? (Add social contexts)

35. What’s next? Still, like many researchers working in this area, Hendler is already looking beyond emerging Semantic Web strategies and related technologies that are now collectively called Web 3.0. “This stuff is new and exciting,” he says. “ But I look at it this way: I started playing with the Semantic Web back in the 1990s. As a researcher, I’m not content to sit around and exploit Web 3.0; my job is to help create Web 4.0.” “Engineering the Web’s Third Decade,” CACM March, 2010
