摘要

With the popularization of technology such as service-oriented computing(SOC), and cloud computing, the services provided by suppliers can be invoked through standard Web services and provided to users. In recent years, owing to the exponential increase in the number of service providers, there are more and more services on the internet with the same function but different Qualifies of Service (QoS). Meanwhile, the increasingly complex user's needs for functionality and QoS can no longer be met by a single service. Therefore, how to integrate a large number of services into a comprehensive web service to satisfy users' QoS has attracted the attention of many scholars. In this paper, we introduce the web service composition model and the definition of relative QoS attributes and summarize the QoS-based web composite service selection methods according to the type of method. Finally, the shortcomings of each type of algorithm are shown.
