基于行为一致性匹配面向组合流程的服务发现

Service Discovery for Composite Process Through Matching of Behavioral Consistency

面向组合流程的服务发现是一个组合流程的实例化过程,通过该过程可以得到组合服务.提出了基于行为一致性匹配面向组合流程的服务发现方法.该方法通过行为一致性的概念建立了服务行为与角色行为需求间的行为语义匹配关系.将面向组合流程的服务发现问题转换为以路径识别为基础的树匹配问题.提出了相应问题的求解算法.实验表明,所提出的服务发现方法能够有效地保证所发现服务的业务完整性及服务与组合服务间的行为一致性,且具有良好的时间效率.

Service discovery for composite process is actually an exemplifying process through which the composite service is available. A new way is suggested to find the web service for the composite process through matching of behavioral consistency. Such approach establishes a behavioral-semantic matching relation between the service behavior and the role behavior needed to play. Thus, the problem of service discovery for composite process turns into that of semantic tree matching on the basis of path identification, and the mlution is given to it correspondingly. Experimental results shows that the approach suggested can make sure of the completeness of the service discovered effectively and of the behavioral consistency of the service with composite service as well as the high-efficiency runtime.
