Mobile user agent with user ontology for personalized web service access

Web service is a popular standard to publish services for users. However, diversified users need to access web service according to their particular preferences. Using agent and user ontology seems to provide such badly-needed personalized web service search. Further, mobile agent can be used in the search. However, how to deploy it in a mobile device with limited power and memory is an issue. In this paper, we present a mobile user agent architecture, in which a mobile agent migrates from one location server to another to execute a user task. Most importantly, user ontology with both static and dynamic information is defined by web ontology language (OWL), through which the location server can do personalized search of services. In addition, mobile agent reduces network load. Further, it can be dynamically deployed on a location server that connects to a mobile device. This reduces power and memory consumption.
