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 visualisation), 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, etc. The aim of this blog is to report on the activities of our research group, and make results accessible to a wider audience.
