eLearning and the semantic web

This is the abstract of an article entitled "eLearning based on the Semantic Web," by Ljiljana Stojanovic, Steffen Staab and Rudi Studer:

Abstract: eLearning is efficient, task relevant and just-in-time learning grown from the learning requirements of the new, dynamically changing, distributed business world. The term „Semantic Web” encompasses efforts to build a new WWW architecture that enhances content with formal semantics, which enables better possibilities for navigating through the cyberspace and accessing its contents. As such, the Semantic Web represents a promising technology for realizing eLearning requirements.
This paper presents an approach for implementing the eLearning scenario using Semantic Web technologies. It is primarily based on ontology-based descriptions of content, context and structure of the learning materials and thus provides flexible and personalized access to these learning materials.
