A Trusted Composition Evaluation Model to Support Web Services Coordination in Multi Domains

摘要

With the widespread development of web services application in multi-domains, more and more researchers have focused on the quality of web services composition. However, the research on the evaluation method for web services composition is still little nowadays. Therefore, a QoS-driven Trusted Composition Evaluation Model (TCEM) is proposed in this study, it can judge the business stream effectively and comprehensively by choosing an appropriate and trusted evaluation method for the generated services composition chains. Furthermore, on the basis of Case-Based Reasoning (CBR) and the retrieval mechanism oriented to web services coordination, the TCEM-based execution engine and algorithm is implemented to evaluate the quality of service composition. The proposed algorithm has the satisfied result compared with the traditional method, and it shows more efficient and trustworthy where web services composition is widely used in multi domains.
