An Adaptive Web Information System Based on Web Services

Nowadays, with the great diffusion of mobile technology, and ubiquitous systems, the context has become the ear and the eye of Information Systems. These systems are more and more based on the usage of Web Services which are designed to support interoperable application-to-apptication interaction over the Web. In this article, we present our contribution aims at proposing a new architecture of Web Information Systems, supporting the adaptation process to the user context and returning to the user a list of Web Services adapted to his context. This architecture is based on an extension of AHA! architecture adding an adaptation layer containing various components dedicated to the context adaptation. So, our aim is to build an Adaptive Web Information System based on Web Services. Finally, we present an algorithm which we use to build a user contextual profile "Profile-Context-User (UCP)" containing only the user preference that can be satisfied with the context.
