Abstract: 在服务组合中,动态环境的变化可能导致参与组合的Web服务行为发生变化。为此,提出基于自适应框架的Web服务选择算法,用于获取公共服务注册处的信息 ,并将其记录在本地绑定库中,利用链接分析算法获得绑定库某一时刻高链接度的Web服务,实现服务选择。实验结果证明,该算法可在服务组合中动态选择高质 量的Web服务,降低由服务质量变化造成的服务组合失败率。
English Abstract: In service composition,due to dynamic changes in the environment and reasons for the services itself,the behavior of the Web services involved in service composition may evolve and influence the service composition results.An adaptive service selection framework is proposed to solve the problem.The information from public service registries is captured and recorded locally in the binding repository,then link analysis algorithm is applied to the binding repository to get the highly linked services at the moment for service selection.Simulation experiment results show that the framework and the algorithm can select high-quality services dynamically,and reduce the failure rate of service composition results caused by evolving Quality of Service(QoS).
