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
 
The Semantic Web (ca. 2001) (Berners-Lee, Hendler, Lassila; 2001)
Semantic Web ca. 2010 ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Two very different sorts of use cases ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Widely varying use ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Why ? ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],In this view OWL is a formal knowledge representation standard
The argument for this seems compelling ,[object Object],Which one do you want your doctor to use?
But the cost is high ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
The alternative ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],“ linked data” often used to describe this low semantics Semantic Web (slogan: a little semantics goes a long way)
Semantic Web Applications ,[object Object],RDF Triple Store Dynamic Content Engine HTTP RDF Web App (w SPARQL) RDF Triple Store … HTML 2008 examples include sites from "regular" Web players such as Dow Jones, Reuters and Yahoo!
cf. Yahoo mixes RDF with other technologies: at Web scale Dave Beckett, SemTech 08 http://www.semantic-conference.com/session/733/
Linked Data + Semantics ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
The data is out there Example: the linked open data cloud now has tens of billions of triples and is growing rapidly
Government Data on the Web
Moving data.gov to linked data (UK) ,[object Object]
Moving data.gov to linked data (US) ,[object Object],• Plans for a semantic.data.gov in OGD implementation plans,, but unfunded
Adding Meta-data
Pump through to Google Viz for demos
Data.gov + epa.gov
Adding some Web magic Web Analytics Social Data Networks External Links
Mashup w/Web content
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.
Semantic Search IEEE Computer, Jan 2010; IEEE Computing Now, Feb 2010 (free)
Semantic Search examples T2 (twine.com) TipTop ( feeltiptop.com )
Web 3.0 examples Semantic classified (bintro.com)
Trialx.com
Web 3.0 examples
Web 3.0 examples Social database (freebase.com)
Tiptop health Ok, so we have a way to go on this one 
Web 3.0 excitement (hype?) ,[object Object],[object Object],[object Object],[object Object]
1B computers (mostly owned by a few large companies) 3B cell phones (most are Web enable)
Sem Web going mobile? (Add social contexts)
Summary ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
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

Web 3.0 emerges as Semantic Web technologies find success

  • 33. Sem Web going mobile? (Add social contexts)
  • 34.
  • 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

  3. And for 4.0 - one big change is the move to mobile computing – there are now many billions of more cellular phones than laptops in the world, and these machines are becoming more and more capable – we need to combine communications and information technology to create the mobile Web
  4. The slogan of Rensselaer is “Why not change the world” – with a combination of Web, Data and Communications technology, that is just what we are doing!
