An Ontology Infrastructure for an E-Learning Scenario

Abstract

Selecting appropriate learning services for a learner from a large number of heterogeneous knowledge sources is a complex and challenging task. This article illustrates and discusses how Semantic Web technologies such as RDF and ontology can be applied to e-learning systems to help the learner in selecting an appropriate learning course or retrieving relevant information. It presents the main features of an e-learning scenario and the ontology on which it is based, then illustrates the scenario ontology with the training domain and the application domain. Finally, it presents semantic querying and semantic.
