Whatizit is a text processing system that allows you to do textmining tasks on text. It is also available as a Web Service whose underlying idea is to ensure that software from various sources work well together. Whatizit is built on open standards of Simple Object Access Protocol (SOAP) and Web Services Description Language (WSDL). For the transport layer itself, Web Services uses most of the commonly available network protocols, especially Hypertext Transfer Protocol (HTTP). For more information on WSDL please refer to the W3C WSDL v1.1 Document.
