Abstract

Semantic web service composition is about finding services from a repository that are able to accomplish a specified task. The task is defined in a form of a composition request which contains a set of available input parameters and a set of wanted output parameters. Instead of the parameter values, concepts from an ontology describing their semantics are passed to the composition engine. The composer works on a repository of services. The parameters of these services are semantically annotated in the same way as the parameters in the request. The composer then finds a set of services fulfilling the request -- the composition. If the input parameters given in the request are provided, the services of this set can be executed and will finally produce the wanted output parameters. In this paper, we introduce our new, improved composition system with which we will take part in the Web Service Challenge 2008.
