With the increasing growth in popularity of Web services, discovering relevant Web services becomes a significant challenge. The introduction of intentional services has been proposed to bridge the gap between low level, technical softwareservice descriptions and high level, strategic expressions of business needs for services. Current Web Services technology based on UDDI and WSDL does not make use of this "intention" and therefore fails to address the problem of matching between capabilities of services and business user needs. In this work, we are interested in extending existing approaches for the description of intentional Services. Our proposed approach is an extension of the W3C recommendation on semantics for Web services (SAWSDL) and uses two types of ontologies: verb ontology representing syntactic and semantic concepts related to verbs, and product ontology, which is a Domain Ontology containing the concepts defining a common vocabulary for all objects manipulated in the business domain. We present how our approach can help publishing intentional services.
