Towards an automatic non-deterministic web Service Composition platform

This paper describes work in progress towards the implementation of an online Web Service Composition system. The system adheres to the reusable nature of web Services by utilizing existing open source projects as sub-elements and is based on the most prevalent web service standards. It will treat non-determinism as an inherent characteristic of the problem and tackle it through the use of contingency planning. To the best of our knowledge, the final system will be the first online application of its kind able to support various stages of Web Service Composition. In this paper we focus on the evaluation framework for the proposed system, based on an existing test collection and three detailed use case scenarios, and a manual composition module than can produce workflows corresponding to them.
