Semantic Web Research

Photo: Karl Öfverström

The Semantic Web is an extension of the traditional Web in which interlinked data with well-described semantics has been added in a machine-processable form. As a result, we can view the whole Web as a large set of interconnected knowledge bases that can be queried and browsed both by software systems and by human users.

Research into the Semantic Web at LiU includes areas such as:

  • Ontologies and ontology engineering (ontology design patterns, ontology alignment and completion, ontology and alignment visualization).
  • Graph databases and triple stores.
  • Querying interlinked data on the web.
  • RDF stream processing
  • Complex event processing.
    ​

Our group

We are researchers from different labs in the Department of Computer and Information Science (IDA) at LiU, with a common interest in the Semantic Web.
