Web-Based Knowledge Representation Repositories

To support the development of semantic integration tools and methods, suitable test data is needed. Many schemas and ontologies have been developed in different domains, but what is often needed is a set of ontologies about the same subject. For this purpose we gathered 47 test ontologies that students produced, all covering the same domain (the university department). On average the ontologies contain 30 classes, 50 relations and 200 instances. The data is represented in RDF and stored in the Sesame system, so that it can easily be queried using SeRQL.

We added another 39 ontologies that were produced by our students during the 2004 course. The subject here was a television guide.

Warning: the Sesame repositories are no longer accessible. The OWL files are still available though.
