A Context-aware System Architecture using Personal Information based on Ontology

Context-aware applications can satisfy users' information needs without consuming too much time in discovering information adaptive to users. In this paper, we propose a personalized information system to provide more user-oriented information considering context information such as a personal profile with preferences, location, traffic condition, weather, time, event, and so on. Our system architecture is designed to support an effective execution usage on Web services and client applications. We implement a map viewer using a shape type of map format files with points of interest (PoI) information. Also, our system can provide associated search results from relations between the objects using context ontologies modeling created by the categorized layers of geospatial data.
