Ontology based context aware e-learning system

With the fast development of e-services and the necessity to use information provided by users and their operating environments, Context-Aware Service (CAS) has emerged as a new paradigm of software engineering to dynamically respond to every change in the status of the user's context. Context-aware Service can dynamically capture a range of information from its environment and this information represents a context, the application adapts its execution according to this context. An important challenge in ubiquitous computing is context modeling. Ontology based models presents a suitbale instrument for context modeling. In this paper, we provide an architecture for the development of context aware services for an e-learning system, we also present our context metamodel and how the use of ODM (Ontology Definition Metamodel) can be beneficial for ontology modeling.
