Automated Retrieval of Semantic Web Services: A Matching Based on Conceptual Indexation

Web services are taking an important place in the distributed computing field, as well as in the electronic business. In this paper we present an initial research which deals with the issue of automated service retrieval. For that, we propose an approach that exploits the service interface (inputs/outputs) and the domain ontology, in order to conceptually index the web services. After that we compute a similarity score between the request and the indexed web services through the cosine measure. An experimentation based on the OWLTC test collection is described to evaluate the system. The obtained results are very encouraging and confirm the suitability of the solution.
