Populating parameters of web services by automatic composition using search precision and WSDL weight matrix

Abstract

Web service composition is meant for connecting different web services according to the requirement. This research implements a system for invoking the web services according to the users' requirement and composing the services if required. The unknown values of input parameters are populated by composing available web services automatically and dynamically. The methodology used here is searching the requested services according to the functional word using Bing search engine, processing the search results which have high precision, computation of WSDL weight matrix to select suitable web services for user satisfaction, and populating unknown input parameters' values by composing the web services. Composable web services are found by intra-cluster search and inter-cluster search among different operations of community web services. Composition rule is framed for the services involved in resolving unknown values, pre-condition and effect elements are tested before composition, and web services are invoked according to the composition rule.
