Automated Service Composition with Adaptive Planning

Service-Oriented Computing is a cornerstone for the realization of user needs through the automatic composition of services from service descriptions and user tasks, i.e., high-level descriptions of the user needs. Yet, automatic service composition processes commonly assume that service descriptions and user tasks share the same abstraction level, and that services have been pre-designed to integrate. To release these strong assumptions and to augment the possibilities of composition, we add adaptation features into the service composition process using semantic descriptions and adaptive extensions to graph planning. keywords: Services, Task-Oriented Computing, Composition, Software Adaptation, Planning, Workflow Languages, Tools.
