Web Service Search Engine

Abstract

An increasing number of Web services are created and composed to construct complex business processes. Selecting an appropriate service from a lot of independently developed services which have the same functionality but different QoS properties is essential for the effective use of the composite service. However, the public UDDI Business Registry, the primary service discovery mechanism over the Internet has been shut down permanently and existing approaches heavily rely on the information in WSDL (Web Service Descriptive Language) files, which is quite limited to understand the web service’s functionality and QOS. The limitation of information weakens the effectiveness of existing approaches. In this paper we proposed web search engine on the basis of WSDL and WADL (Web Application Descriptive Language) file descriptions, Web service related description on Internet, Web service reputation by feedback of user and QoS of Web service. We use this information for effective to choose the best of web services.
