Through Personalized Web Service Composition Specification: From BPEL to C-BPEL

Over the last few years, Web services technologies offered a new and successful way for interoperability among web applications. A Web service is a software system designed in a way that other software components and humans can discover and invoke to satisfy different needs. The vision of WS as a software component allows to combine several WS, providing a global value-added WS, called composite WS. Although there are several researches in web services composition, more effort should be focused on its personalization, particularly regarding how well the composition results correspond to what the user really wants. Accordingly, we present in this paper an approach that may contribute to the personalization of web services composition specification. Our approach is a context-based proposal that makes services composition specification more efficient by taking into account both user context, needs, and preferences and web services context, and by integrating them to the composition process. In addition, to permit the reuse of specifications, we enhance BPEL by developing a specification language based on context to be used in composition that we called C-BPEL.
