Abstract

We developed a regional information retrieval system for the mobile environment, called “Mobile SeoulSearch”. This system provides regional information related to the specific position where a mobile user is located. Here the regional information is derived from the Web space. For utilizing the features of mobile environment, and coping with limitations of user interface in mobile devices, several methods are proposed: Firstly, using user's location information which is obtained in real-time, a method that regional information related to the mobile user's specific location is provided in real-time to mobile devices, is proposed. Using this method, the mobility of mobile devices is maximized, and the limitation of input methods on the devices is coped with. Secondly, a layered and reconfigurable graphical user interface similar to CardLayout in Java, is proposed so that lots of regional information is displayed efficiently in spite of very poor user interface in mobile devices. Finally, methods for gathering Web pages and indexing regional terms, are proposed to provide mobile users with the regional information effectively. The efficiency of these methods are verified through the development of “Mobile SeoulSearch”.
