Extracting Public Web Service description from WWW

摘要

Web Service is a software component that provides business functionalities to other applications over the Internet. XML standards provide the base for web services. Most of `web service providers' are now publishing web-services on their own websites. Consumers who want to understand the functionality of a web service will need to see description of the web service in order to use it purposefully. There are two types of descriptions that are available with a web service, i.e. structural and non-structural. Web Service Description Language (WSDL) file contains the description of the web-service; the textual description is the documentation element in WSDL file. The description in the WSDL file is normally missing or less then IK words which make it hard for the consumer to understand it using the WSDL file. The proposed approach helps the consumer of a web service in understanding its functionality by finding the details present on the pages over World Wide Web using Google search and information filtering techniques.
