Semantic Web

Semantic web describes data on the web maintaining its semantics in such a way that other web applications may "understand" the meaning of the data with only little effort. Semantic web has developed from a research initiative in the late 20th century into a fast growing infrastructure for application domains, such as bioinformatics or eGovernment. This infrastructure is driven by W3C standards as well as by methods and technologies from a diverse area of computer science disciplines, such as artificial intelligence, databases and human-computer interaction. This course will give an overview and introduction to core and current semantic web technologies, including: 

  • Description Logics;
  • XML, RDF, OWL;
  • Ontologies, ontology engineering, ontology design patterns;
  • SPARQL, named graphs, networked graphs;
  • Linked open data;
  • Information extraction;
  • Semantic Web services

Required Knowledge

Basic knowledge about about logics and data engineering recommended.

Acquired Competence

The student will be enabled to design and develop semantic Web applications. The student will be enabled to progress Semantic Web technologies in order to broaden and facilitate their use. The student will be enabled to understand the interaction of different standards, their technical implications as well as the social processes that underly various Semantic Web applications.
