中文摘要：

传统的Web服务缺乏语义信息，如何自动地根据服务请求，进行服务的动态组合成为一个迫切需要解决的问题。语义网使得网络中所有的信息都是具有语义的，使计算机能够理解和处理。通过把Web服务抽象成为具有输入和输出接口的实体，提出了基于接口匹配的Web服务组合方法。该方法通过计算服务接口之间的匹配程度，找出其潜在的依赖关系，能够自动、动态地发现潜在的Web服务，从而实现Web服务自动组合。

英文摘要：

The traditional Web service lacks semantic information. How to compose Web service dynamically according to service request becomes a problem urgently to be solved. All the information in the semantic Web has semantic meanings, it can be understood and processed by computer. This paper proposes a Web service composition method based on interface matching by abstracting Web service as an entity with input and output interfaces. The method can discover the potential message dependency by computing the matching degree between service interfaces, and can discover potential Web service automatically and dynamically, therefore realizing the automatic composition of Web service.
