How to apply CBR methods in Web service composition?

The emergence of web services as a new technology supporting the future Web has motivated several researchers to investigate in this field. In addition, the possibility of selecting and integrating Web services, in or between organizations, is very useful for the improvement of their profitabilities. In such a case, we introduce the term of web service composition. In this paper, we propose an approach called WeSCo CBR (Web Service Composition founded on Case Based Reasoning) that aims at enhancing the process of web service composition by using case based reasoning technique which originates from artificial intelligence. Furthermore, we regard efficient description and management of information semantics as a major requirement to enable semantic interoperability. We opt to integrate ontology so that we can apply a reasoning to help perform meaningful web service composition.
