In the first section we give avery short survey on current research on web-based educational systems and related problems. In the second section we argue that knowledge representation and ontologies may offer solutions to basic problems in this area. Since a well-founded system of concepts, i.e. an ontology, will significantly advance knowledge sharing and interoperability. This will enable both the design of reusable functional components and the design of authoring tools. In the third part we introduce and discuss our approach of organising system knowledge in an ontology. Finally, we propose an approach how ontologies and Knowledge Space may becombined for improving both user modeling and intelligent problem solving support.
