基于流程的Web服务发现

Process-based Web Services Discovery

支持基于流程的Web服务发现是提高企业集成度和灵活性的一个重要问题.由于Web服务的松散耦合环境,发现的Web服务流程未必完全相容.提出一个能够反映Web服务流程控制特点的流程模型tFSM,基于tFSM模型定义了Web服务流程的相容性和相容度,并给出一个计算Web服务流程相容度的算法.利用这些核心工作,可以实现一种基于流程的Web服务发现方法.

Supporting process-based Web services discovery is an important issue for enterprises to increase their flexibility.As the loosely-coupled nature of Web services,the discovered processes are not necessarily compatible.This paper first presents a process model named tFSM for Web services,and then defines the compatibility degree of Web service processes based on the tFSM model.An algorithm for computing the compatibility degree of two processes is also designed.Those works form an effective approach to process-based Web services discovery.
