摘　　要：基于结构匹配的Web服务发现方法常常由于XML Schema定义的灵活性,使得一些本来语义相近的Web服务由于描述结构的不同而匹配失败,且计算开销较高。为此提出了一种基于细粒度数据语义的SAWSDL服务匹配方法和一个数据语义分解转换算法。将每一个消息级参数转换为多个细粒度的数据参数,使得基于消息级的SAWSDL服务匹配转化为更细粒度的数据语义匹配。实验结果表明该方法能够提高Web服务的效果,且计算开销较低。The service discovery methods for Web service based on structure matching has higher computational overhead and can lead to failed matchmaking of the Web services with similar semantics due to the difference of different structure definitions owing to the flexibility of XML Schema. To solve this problem, a so- called fine-grained data semantics based method is proposed, which can be obtained by a transformation algorithm that decomposes parameters at message level into a set of fine-grained data parameters. Experiments show that the orooosed method can improve the effectiveness of service discovery and has lower computational overhead.
