As the Internet Web services increased, how to find a web service which can meet user's requirements quickly and accurately has become a problem to be solved .Now many kinds of web service methods based on semantic are based IO matching .They used other ways to supplement while semantic matching is failed. However the accuracy of semantic web service discovery based on IO matching purely is not high enough, the Algorithm of semantic web service discovery which is based on constraint extraction and structure analysis is proposed. It is divided into two parts. First part is to carry out the concept of semantic matching based on constraint extraction .Then it uses algorithm based on structure analysis while matching is failed, aiming to assess the structural similarity of the desired vs the retrieved services and the semantic similarity of their identifiers. This article uses owls-tc2.0 as test set to test this method .The experimental results show that this method improves service discovery accuracy effectively.
