Semantic Web Technologies

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



  • Java programming skills are required to pass this course!
  • Preferably, some experience with software development
  • To pass the course you have to fulfill the following requirements:
    • Pass the final exam (you have to get a 4.0 or better in the exam to pass this course)
    • Successfully work in a group on a project idea (programming!), present the results and write a detailed report
  • The final grade is determined from the grade achieved in the final exam (50%) and the grade achieved in the team project (50%).



  • Lecture: Wednesday 12:00 - 13:30, starting September 3, Room: A1.04
  • Tutorial: Tuesday 15:30 - 17:00, starting September 9, Room: A2.06 The tutorial got shifted to a different slot to prevent collisions with other courses.
