Context- and QoS Aware Personalization for Web Services: Web Information Extraction Case Study

One of the major challenges faced by the Web services platform is how to compose a more appropriate new value added web service according to the user's requirements and preferences, and adapt it at runtime. To this end, we suggest in this paper a QoS-oriented approach to build more efficient composite web services and personalize this composition on-the-fly by taking into account user context, requirements, and preferences and also non-functional properties of web services involved by this composition. These non-functional properties concern the Quality of Service (QoS) as well as the context of service execution.
