Automatic generation of web service workflow using a probability based process-semantic repository

Abstract

Workflow management system has been utilized in the web service environment to make mass of different web services work cooperatively. In this paper, the authors propose a novel automatic generation method of web service workflow and build an e-travel system, which could generate travel process automatically according to passenger's requirements. The e-travel system is a dynamic and self-adaptive virtual travel agency, which uses a probability based process-semantic repository as the foundation. This paper will carefully discuss the process-semantic repository and the automatic generation algorithm of web service workflow based on it. At last, some experiments are presented to evaluate the efficiency of the e-travel system with the process-semantic repository. © Springer-Verlag Berlin Heidelberg 2007.
