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
