Description/Abstract

The World Wide Web offers access to a wealth of educational material; yet these are often weakly interlinked and fail to make explicit any real-world relationships. Ontological engineering support has been identified and stressed as one of the key limitations to overcome in building next generation web-based educational systems enabling knowledge sharing and reuse. In this paper we address this important issue by combining the strengths of hypermedia systems with the benefits of ontology-based systems to provide high quality, semantic-enabled web-based educational portals. We present Ontoportal: an ontological hypertext framework for building generic web-based educational portals. We also describe two simple case studies showing how the framework could be used to create ontology-based metadata and generate educational portals semantically interlinking various web-based educational resources (tutorials, assessments, courses, etc) for learning and teaching.
