| 摘 要： | 为了在服务发现中提高效率及准确率,在服务匹配过程中引入了服务执行状态的变迁等因素即服务的过程模型。而Petri网能够把Web服务的过程模型进行形式化描述．在服务发现中引入Petri网,通过Petri网描述web服务的过程模型,再对Petri网进行语义标注,最后通过计算过程模型的相似度来实现基于Petri网的语义Web服务发现匹配．这种方法结合现有采用功能性参数匹配的语义web服务发现对提高服务发现率,尤其对改善服务发现准确率起到了一定的作用．

| Abstract: | In order to improve efficiency and precision ration in service discovery,service process model is introduced in service matchmake.Petri net is adopted as a modeling language for the specification of service process model.Thus this paper proposes Petri net to support semantic web service discovery.So converting process information to Petri net description,it is applied in match of services to process similarity computation.It can improve efficiency and precision ration in service discovery. |
