Wireless Web Services using Mobile Agents and Ontologies

Abstract

We discuss the integration of two contemporary service technologies: Web services and mobile agents. We exploit the capabilities offered by mobile agents to query and invoke semantically enriched Web services without the need for simultaneous, online presence of the service requestor. Such service setting is ideal for wireless/mobile computing, where user terminals are not necessarily online during their entire session. To improve the capabilities of service registries met in the Web services reference architecture, we exploit the advantages of the semantic Web framework. Specifically, we use enhanced registries enriched with semantic information that provide semantic matching to service queries and published service descriptions
