A WSDL structure based approach for semantic categorization of web service elements

Abstract

This paper introduces a semantic categorization technique whose goal is to classify web service structural elements into their semantically described counterparts. The semantic representations of the web service elements are provided by a set of predefined ontologies. Our technique proposes a three layer categorization approach based on the WSDL document structure, i.e. its operations and input/output parameters. By means of the proposed categorization technique, automatic web service invocation is enabled in addition to semantic annotation of web service. Apart from presenting the theoretical details of the semantic categorization technique, this paper conducts preliminary assessment of its performance in terms of classification accuracy and compares it to one of the most known and successful web service classification tools. © Springer-Verlag Berlin Heidelberg 2010.
