| 摘 要： | 随着Web服务技术的发展与广泛应用,提供相同功能的Web服务越来越多,而如何在其所提供的Web服务中选择最优服务成为关键问题.传统的基于服务质量(QoS)模型的选择方案已不能满足此要求.提出了一种基于信誉模型并结合QoS的优化选择方案,首先利用工作流组织模型确定服务使用者之间的信任度结,结合可信用户的反馈评价值,确定服务的主观信誉度,然后根据Web服务的QoS量化模型,计算出客观质量值,最后结合二者选出最优的服务.

| Abstract: | With the rapid development and wide application of Web service technologies,large growth in number of Web services as well as the growth in the number of registries makes this replication impractical.one of the main problems is that,how to select the optimal services from a set of requirements satisfying services in Web services composition.In practice a model for Web service discovery and selection based on Quality of Service(QoS) constraints is cannot cope with such kind of request s very well.A method to... |
