Research And Implementation Of Web Service Registry And Similarity Searching

During the tools integration in the distributed collaborative development environment, business functions should be administrated universally in service resources. Service registry supports the registration, discovery and accessing of service resources, which contributes in serive resource sharing in the tools integration.Service metadata is used to design a data model on the basis of thorough analysis of WSDL 2.0 data structure and the UDDI registry information model. In this paper, a layered and extensible service registry center, RCRegistry, is proposed according to the data model. Web services can be registered with RCRegistry in two ways:UDDI and Registry. While the UDDI way enables web services to be registered in the UDDI center, the Registry way provides similarity search on the basis of data model with service metadata. Moreover, concerning the current service discovery problems, a hybrid similarity search method for web services is proposed which associates serivece semantics and service structure with customized weight. Experimental results demonstrate that RCRegistry implements universal description, discovery, and Integration of Web services. Besides, the hybrid similarity search algorithm for web services can select similar services effectively, which has a higher precision than the other existing algorithms.
