Web service reputation measurement based on quality of service similarity
Ying Jiang · Computer Integrated Manufacturing Systems · 2008
To improve the flexibility and authenticity of Web service reputation measurement,a Web service reputation measurement model based on the similarity of advertised and factual Quality Of Service(QoS) was proposed.Upper and lower QoS ontology were designed to describe the semantic of QoS and the hierarchical QoS item system.Similarity algorithm for QoS was proposed which supported the hierarchical QoS.Subsequently,a statistics-theory-based Web service reputation measurement method was put forward which using QoS similarity to compute Web service reputation.Evolution trend and fluctuation of QoS were taken into consideration in reputation measurement with forgetting factor and fluctuating factor.Experiments showed that this model was flexible and practical.
