Paper Abstract:
|
In this paper, we present a semantic web services composition framework based on a distributed architecture and on semantic and uniform based-ontology service descriptions. Central to our framework is the use of the concept of community of services. This concept provides means to describe services with the same language based on the community ontology. Thus, the community constitutes a unified, a homogeneous and a consistent access interface to existing and heterogeneous e-services which propose similar functionalities for services belonging to this community. Moreover, based on OWL-S language, our framework supports a rich expressivity in services and user constraints descriptions, and takes into account the nondeterministic behaviors of e-services instances, in particular when their internal state cannot be predicted a priori. |
