A SOA-based Model Supporting Adaptive Web-based Applications L. Ardissono, R. Furnari, A. Goy, G. Petrone and M. Segnan ABSTRACT Service Oriented Architecture (SOA) supports the integration of distributed and heterogeneous services by offering Web Service composition standards which describe service composition as a business process. However, the composition model proposed in SOA does not explicitly deal with personalization and context-awareness. In order to address such limitations, we have developed the CAWE conceptual framework. In this paper, we describe the personalization support offered by our framework to the development of context-aware, adaptive web-based systems. CAWE handles the integration of heterogeneous services and information sources; moreover, it manages long-lasting interactions with multiple cooperating users and it personalizes the business logic of the application by adapting the workflow activities to be carried out.
