摘要： 现有Web服务发现方法未考虑过程行为的相关信息，导致所发现的服务不能较好地满足用户需求且查准率较低。针对该问题，提出一种基于OWL-S过程模型的Web服务发现方法。将OWL-S过程模型转化为过程图，根据两过程图的相似度，判断两服务过程的匹配程度。实验结果表明，该方法能准确地匹配两服务的过程模型，具有较高的执行效率和较好的匹配效果。

Abstract: Existing Web service discovery methods don’t consider the behavior of the process related information, therefore the found service can not meet the demand of user and has lower precision. Aiming at the problem, this paper proposes a Web Services process discovery method based on Web Ontology Language for Service(OWL-S) process model. It transforms OWL-S process model into process graph, then calculates the degree of matching of two service process models according to the similarity of two process graphs. Experimental result shows that this method can accurately match two service process model, and it has the high efficiency and good matching effect.

Key words: Web service, Web Ontology Language for Service(OWL-S), process model, process graph, similarity, process matching
