Adaptive hypermedia for the semantic web

In the area of technology enhanced learning reusability and interoperability issues essentially influence the productivity and efficiency of learning and authoring tools. This paper aims at addressing the issues of missing standards in the area of adaptivity and personalization, what causes interoperability problems that are usually solved by means of the Semantic Web. There are two basic approaches how to overcome the interoperability problems - one attempts to do it via standards and the other by means of the Semantic Web. In practice these approaches meet and many existing solutions are based on ontologies that take into account the existing standards and try to integrate them. On the other hand, these ontologies can help us to achieve a certain kind of consensus and to contribute to the harmonization of the existing standards.
