Abstract :
A key challenge in composite Web processes is that the quality of participating services changes during the life time of the process. It is necessary to find an available equivalent service to substitute the failed component which has been made unavailable. In this paper different from the previous method based on recompositing the Web process, we present an approach of discovering the ldquosame skillrdquo Web services to replace the expired one by using the service expiration times.
