A Domain-Oriented Evaluation Model for QoS in Web Service

With the development of Web service technology, SOA has so many applications in industries. How to evaluate a domain oriented service becomes an important issue at present. This paper puts forward an extended SOA (exSOA) architecture and a domain expert-based evaluation model for Web service. It evaluates the candidate service by considering the evaluation result from domain expert and the constraint information from service consumer. This model decreases the influence of subjective factors from service consumer and increases the fairness of the evaluation result.
