Electronic marketplace consists of many competing companies who supply each other with web services. The rapid growth of the number of Web services makes finding, selecting and combining them a desirable but challenging task. In this paper, we are proposing the Ontology Web Language (OWL) to capture the content knowledge and Web services. The proposed architecture is part of the mFinance project that utilizing ontologies to describe knowledge and services. We are prototyping a service aggregator that serves as a service repository. It keeps descriptions of services that are accessed by the requester agent and advertised by the service provider. We show how service description, selection and composition are possible using ontologies. Keyword: Knowledge Representation, Ontology, Semantic Web Service, E-Commerce
