Semantic Web Technologies (HWS 2019)

Course Description

The term „Semantic Web“ was coined in 2001 when Tim Berners Lee (the inventor of the World Wide Web) and others presented their vision of an intelligent web in the „Scientific American“. The Semantic Web aims at the development of methods that help to automate the interpretation, aggregation, evaluation and comparison of information on the Web.

This course gives an introduction to the technical foundations of Semantic Web Technologies, including knowledge representation and query languages, as well as logical inference. More specifically, it covers the following contents:

  • Vision and Principles of the Semantic Web
  • Representation Languages (XML, RDF, RDF Schema, OWL)
  • Knowledge Modeling: Ontologies and Linked Data
  • Logical Reasoning in RDF and OWL
  • Commercial and Open Source Tools and Systems
