The Web and Media group is part of the Computer Science department at the VU University. The key research themes of our group are: Ontology Engineering and Semantic Web, Intelligent Systems and Services, and Networked Business Modelling and eBusiness. We are interested in both the “product” aspects (the resulting languages, ontologies, alignments and patterns), as well as the “process” aspects (practical ‘how-to-do-it’ guidelines and support tools).We are active participants in W3C activities such as, "CSV on the web" and "data on the web best practices". We actively develop open-source software, e.g. SWI-Prolog, ClioPatria.
