4. Semantic Web Challenge Goal: to apply Semantic Web techniques in building online end-user applications that integrate, combine and deduce information needed to assist users in performing task Certain minimum criteria: –Meaning of data has to play a central role –Heterogeneous information sources, under diverse control –Open world assumption (information is never complete) –(multi-media, commercial potential, scalability, dynamic data) Semantic Web Challenge –23 submitted Semantic Web applications –19 accepted http://challenge.semanticweb.org/
