Semantic Web research at LiU

Our group

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


Our field

The Semantic Web is an extension of the traditional Web towards having machine-processable content and interlinked data on the Web, with well-described semantics. Ideally, we would be able to view the whole Web as a large set of interconnected databases that can be queried and browsed by software systems as well as by human users. Semantic Web research 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 and complex event processing, as well as applications of these technologies in a number of fields, including open data, security, decision support systems, e-health and e-science.


Our activities

  • Our list of projects and publications gives an overview of the research carried out by the group.
  • Our group organizes a series of regular Semantic Web Seminars at LiU.
