Abstract

Service Oriented Architecture (SOA) is an architectural style that could seamlessly integrate existing software to fulfill dynamic requests in a platform-independent way but the loosely coupled and distributed characteristics of SOA will incur the trustworthiness problem in service composition. In this paper, we utilized the statistical techniques and Petri nets to propose an evaluation method for trustworthy service compositions. The trustworthiness of involved Web Services will be evaluated by analyzing past experiences so that the trustworthiness of the composite service could be estimated from the evaluation of each Web Service and aggregation topology of the composite service.
