Empirical study on location-based Web service based on CC/PP and RDF

In this paper, we present empirical study on new framework of location information service on the Web with CC/PP and RDF. We have implemented a prototype system and explored a new technique to exchange the location of a mobile device on the Web with CC/PP and its exchange protocol to localize a Web service. We have used CC/PP to describe user's context in the form of CC/PP and RDF, and exchange them via HTPP Extension framework to localize Web contents based on the terminal location. In addition, we have harmonized CC/PP with P3P to protect user's privacy and specify the information to achieve the services on a server side. We have investigated a new way for describing such kind of information with CC/PP and its protection mechanism by P3P. Finally, we have developed experimental systems to demonstrate effectiveness of our techniques. We believe CC/PP and RDF can be applied for describing user's environment, and P3P can complement the security aspect of CC/PP.
