Abstract. Due to the availability of huge number of Web services (WSs), finding an appropriate WS according to the requirement of a service consumer is still a challenge. In this paper, we present a new and flexible approach, called SeqDisc, that assesses the similarity between WSs. In particular, the approach exploits the Prüfer encoding method to represent WSs as sequences capturing both semantic and structure information of service descriptions. Based on the sequence representation, we develop an efficient sequence-based schema matching approach to measure the similarity between WSs. A set of experiments is conducted on real data sets, and the results confirm the performance of the proposed solution.

Abstract: 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.
