Content

The term Semantic Web describes an extension of the World Wide Web through meta data and applications with the goal of making the meaning (semantics) of data in the web accessible for intelligent systems e.g. in e-commerce and in internet portals. A central role plays the representation and distribution of knowledge in the form of ontologies. This lecture covers the foundation of knowledge representation and processing and the corresponding technologies and introduces applications thereof. The following topics are covered:

• RDF (Resource Description Framework) and RDF Schema for the representation of meta data and simple ontologies
• The Web Ontology Language (OWL) and its extension OWL 2
• The SPARQL query language
• Rule-based calculi for automated reasoning in the Semantic Web
• Aspects of ontology engineering and editing

Lecturer

Juniorprof. Dr. Birte Glimm
