QoS-aware semantic web service composition concerns finding services from a repository to accomplish a specified task while meeting the Quality of Service (QoS) demands. The composition task is defined in form of a composition request which contains a set of available input parameters and wanted output parameters. If the input parameters given in the request are provided, the services of this set can be executed. Concepts from an ontology describing their semantics are passed to the composition engine. The composer works on a repository of services which posses QoS features. 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. In this paper, we introduce our improved composition system with which we will take part in the Web Service Challenge 2010.
