Abstract

The proposed research is devoted to application of context mediation, an approach for achieving interoperability among semantically heterogeneous databases, for e-Learning. Because the fact that many learning objects are created in various parts of the world and across many cultures these learning objects are semantically heterogeneous, and the delivery of these objects to learners is not effective. The context mediation described in this paper assumes comparison of contexts associated with any learning object and learner, and elimination of semantic conflicts that are detected through this comparison. The comparison of contexts of learning objects and learners uses ontologies as specifications of concepts, their properties and relationships between them in the knowledge domains of courses to be studied. This work is concentrated on the building, contextualization and integration of ontologies, and their use in the context mediation for delivery learning objects to learner's context.
