Concepts and ontologies in web-based educational systems

The goal of this paper is to explore issues concerned with the design of concept/ontology-based WBES and to outline the state-of-the-art in the development of ontology-aware systems that facilitate the reuse, sharing, and exchange of knowledge and components with respect to both their creating and authoring. We hope that it will contribute to defining the path towards a new generation authoring strategies, which will meet the complex requirements of concept-based WBES authoring.
