Abstract:
Service-oriented architecture (SOA) is an emerging approach for building systems based on interacting services. Services need to be discovered and composed in order to meet user needs. Most of the time, these needs correspond to some kind of intentions. Therefore these needs are not expressed in a technical way but in an intentional way. We note that available service descriptions and those of their composition are rather technical. Matching user needs to these services is not a simple issue. This paper defines an intention driven service description model. It introduces a service composition mechanism which provides the intention achievement of a user within a given context. We consider service patterns and we investigate how these patterns can be used in representing reusable generic services and in generating specific composite services.
