Abstract: Service-oriented computing strongly supports the development of future distributed business applications through the use of (web) services. Due to the heterogeneous and evolving nature of business processes, service adaptation is necessary in order to overcome mismatches between the interacting parties. Our long-term objective is to develop a general methodology for service adaptation capable of suitably overcoming semantic and behaviour mismatches in view of business process integration within and across organisational boundaries. In this paper, we show how to adapt a service in order to fulfil a client query requesting a service with certain inputs and outputs. The proposed technique relies on inspecting service execution traces and it generates a service contract tailored to the client needs. Service contracts include a description of the service behaviour (expressed by a YAWL workflow) as well as an (ontology-annotated) signature.

Keywords: web services; service discovery; service adaptation; YAWL; service-oriented computing; business process integration; service execution traces; service contracts; service behaviour; ontology.
