An Approach to Evaluate and Enhance the Retrieval of Semantic Web Services

In order to achieve the (semi-) automatic composition of Web services to business processes and workflows respectively, it is necessary to make use of semantic information regarding the capabilities and further characteristics of particular Web services. In recent years, a couple of approaches have been proposed to achieve (semi-) automatic annotation, retrieval, and composition of Semantic Web services; however, differences in Web service standards and repositories used for the evaluation of these approaches lead to a lack of both in-depth evaluations and comparability of the proposals. In this paper, we present a workbench to test and evaluate the performance of annotation, retrieval, and composition algorithms for Semantic Web services. As a proof of concept we introduce SEM.KOM, a prototypical implementation based on standardized Web service technologies.
