OnLearn: The ontology for managing e-learning resources

In this article, we propose to apply Semantic Web technologies to the field of e -learning. Today, the resources available on the web increases significantly. Information Systems Research existing does not allow users to return documents that meet their exact needs expressed by a query on a document collection. To optimize information retrieval, we propose an approach based on the use of domain ontology for indexing a database and use semantic links between documents or fragments of documents collection, to allow the inference of all relevant documents. This ontology, in OWL format facilitate the management of learning resources. The development environment is used protected ontology. We describe how to semantically index the e-learning resources through semantic annotations. To test the prototype, we use language SeRQL middleware Sesame.
