The term "Semantic Web" was coined in 2001 when Tim Berners Lee (the inventor of the World Wide Web) and others presented a 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.

The courses provide an overview over existing Semantic Web Technology, especially concerning

1. Standardized markup languages for an explicit and machine processable representation of information content
2. Common, standardized vocabularies for phrasing queries and as a fundament for comparing information (ontologies)
3. Extraction and explicit representation of existing information basing on common vocabularies and standardized annotation languages
