Towards a new requirements’ definition methodology using ontologies for Pervasive Games Based Learning Systems

Since a Pervasive Games Based Learning System (PGBLSs) is considered as technology enhanced learning system, it becomes important to enhance the development process. Despite the growing presence of mobile devices and the wireless network communication technologies, users needs satisfaction is particularly challenging due to problems arising from the highly dynamic environments in which services will operate. We propose, in this paper, a semantic model driven requirements engineering process in order to improve the development of PGBLSs. This model is based on an ontology of requirements (RO) as a powerful formalism to assist requirements' analysts for fulfilling changing requirements in PGBLSs dynamic contexts. In such environments, analysts have to establish the relative priorities of requirements for resolving conflicting requests. For this issue, a requirements analysis technique is also proposed.
