A QoS-aware Service Collaborative Evaluation Algorithm to Support Service Coordination in Multi Domains

Abstract

With the rapid development of web service applications and the changing demands of enterprise business, more and more web services are combined into several sequences for some complex tasks in order to reduce the costs and improve the efficiency. Therefore, how to integrate the existed web services to form more complex services to meet the personalized needs for different users, which provide a variety of special functions, have become a new hot research area in the recent years. Based on the present advances of web service composition, it proposes a service collaborative evaluation framework to support service coordination in multi domains. Furthermore, the cooperative control and execution engine (CCEE) for service matching and evaluation is designed and implemented in this paper. For the result of service collaborative evaluation based on CCEE, it uses several evaluation strategies to establish the appropriate combination evaluation algorithm by using the case-based reasoning (CBR) mechanism. Finally, we design an experimental performance for the algorithm discussed in this paper, thus show the optimal and satisfied result of services combination evaluation to the Internet users.
