摘要:
 当前Web服务选择是一个研究热点，很多研究人员提出根据用户对QoS( Quality of Service)属性的偏爱，把指定属性权值计算QoS属性综合值作为服务选择依据。实际应用中，用户对服务的偏爱是主观的，在多备选服务，多QoS属性参照的条件下主观性被进一步放大，会导致所选择的服务并不是最适合的。同时，服务之间在社会层次的相互关系并未在服务选择中被考虑。针对上述两个问题，文中首先设计了Web服务选择二维度量属性模型，引入了社会域的服务作用关系；其次通过QoS约束条件排除不满足用户要求的服务；最后设计了一种基于服务效能偏爱的服务选择方法，并通过实验数据验证了该服务选择方法的可行性、有效性和客观性。
Abstract:
 Currently,Web service selection is a hot point,many researchers have proposed that people could assign attribute weights and calculate integrated value as service selection basis by users’ preference for QoS. But in real life,the user’ s preference for service is sub-jective,in the case of multiple attributes and multiple services,subjectivity is amplified,and cannot choose the proper service. At the same time,the relationship among services in society is not considered in the service selection. In response to this problem,firstly design two-dimensional measurement attribute model for selection of Web service in this paper,introduce the service relationship of social domain. Second,eliminate the services that could not meet users’ demand by QoS constraints condition. Finally,a kind of method of service selec-tion based on users’ preferences for service performance is designed,and by experiment,prove that this method is feasible,efficient,and objective.
