An FCM-based trust classification assessment model for web services

In service-oriented applications, trust assessment of services, such as web services, is a key prerequisite for the choreographer of business processes. However, existing methods and technologies for software assessment are not suitable for web services. In this paper, we present an adaptive trust classification assessment model for web services. This model is based on Fuzzy Cognitive Maps and referenced the Software Trust Classification Specification. It combines the trust evidence model and the dynamic context reputation feedback at runtime. The simulation results show that this model is effective for evaluating trustworthiness of web services by trust evidences at both development stage and runtime adaptively. It also helps studying the evolution of trustworthiness throughout the lifecycle of web services.
