Aimed to enhance the accuracy of Web services discovery in unstructured peer-to-peer networks. A semantic-based Web services matching method was proposed in this paper. Firstly

we designed a service content model for peer-to-peer nodes based on the functional properties. Then

we proposed a use case of computing service

and established a semantic dictionary for it. Finally

object to the service content

we designed a node structure for distributed service publishing and discovery architecture

and the matching algrithm. The analysis result of the computing case showed that the matching degree value had a reasoning distributed property in its domain

and

the matching algrithm meeted the need of the computing service.
