A basic study on information filtering method dealing with user goal

The technologies for telecommunication, GPS, and mobile GIS have rapidly progressed in the last few years. They will allow us to access to the Internet at any time and any place. A user needs to acquire information easily and correctly through a web browser on a cell-phone or a PDA. Our purpose is to build a system providing blog pages written about a facility for a user who is standing in front of the facility. The user can see these blog pages through the web browser on his cell-phone. The system has two technical features. One is extracting users´ goals of using facilities from a common sense database. The other is filtering blog pages based on the goal selected by the user.
