摘　　要：以不动点相关理论为基础,采用数据挖掘和概率统计的方法,对W eb服务行为约束和概率统计语义的问题进行研究和分析。针对传统定性描述调用关系的不足,给出服务调用关系定量描述的方法,并给出W eb服务间调用的不动点函数及相应算法。实验证明,此方法对W eb服务发现是有效的。On the basis of the relavant theories of fixed - point, using data mining and statistical studies, this paper researches and analyzes the semantics of behavioral constraint and probability statistics of Web services. Aiming at the insufficient of traditional qualitative description of the invoking, this paper also presents an approach for it, and defines the fixed - point function of Web services allocation and its calculating way. The experiment proves the approach aiming at Web services discovery is effectiveness.
