Ontology Traceability for the Adaptation of Services in Pervasive Environment

International audienceRecently, interaction with computer applications in a pervasive environment has increasingly benefited from mobile technologies. These technologies generally attributed to the environments of physical and social properties. Therefore, the adoption of these technologies ensures more flexibility and creates new forms of use. The consideration of the context of use in pervasive interactive applications is a field of research known as Sensitivity to context or context-awareness. A sensitive application context must be able to manage the context information in order to provide adequate services. The inclusion of these two components is subject of our contribution. Indeed, to achieve the context management, we adopt the concept of ontology through basic universal descriptions of domain context awareness. Presenting the context of management models based on ontology is very important to adapt the context sensitivity application. This paper presents a formal Context-awareness model based an ontology traceability to provide adaptive services in order to accomplish a specific goal at any moment and any place. The proposed ontology traceability will be integrated into our context platform adaptation platform. In addition, this kind of traceability allows the supervision and management of what is happening at the environment and consequently to improve the service of information visualization offered to users
