【Abstract】 Presently,Web services are generally discovered on a centralized registry,which may lead to many drawbacks.Therefore,a distributed UDDI registry network and DHCS-based discovery mechanism of semantic Web services in P2P environment is presented and discussed.Finally,some metrics are introduced to evaluate the discovery performance on the bases of protecting correct-rate and complete-rate of the examinations.更多还原
