OntoEdu: A Case Study of Ontology-based Education Grid System for E-Learning

Based on several new technologies, such as ubiquitous computing, ontology engineering, semantic web and grid computing, this paper proposes a kind of flexible educational platform architecture for e-learning, which is called OntoEdu. It is composed of five parts: user adaptation, automatic composition, education ontology, service module and content module, among which educational ontology is the core. With OntoEdu architecture, it is promising to gain concept reusability, device and user adaptability, automatic composition, function and performance scalability. In the meantime, the grid-based system design of OntoEdu is also proposed. Experiments indicate that OntoEdu architecture is viable and flexible. At last, the author discusses some problems of OntoEdu and the next work.
