Semantic Web (SS 2011)

 

Semantic Web

According to Tim Berners-Lee, the inventor of the World-Wide Web, the Semantic Web will "unleash a revolution of new possiblities" - the next step of the WWW towards a global information platform. The focus of the Semantic Web are not human-readable web sites but semantic information that can be reasoned over by electronic agents.

Consequently and rigorously, the  World Wide Web Consortium (W3C) has standardized semantic Web Technology

  •  RDF: Resource Description Framework
  •  RDFS: RDF Schema
  •  OWL: Web Ontology Language, etc.

There is an enormous and growing industrial interest in the Semantic Web - reason enough to offer a new course on this topic!

Refer to the module description in the module handbook.

Also see my Master project on the subject.
