Is the information from the Internet helpful for our daily life? Can the mobile computing support our daily shopping or the sightseeing? With the growth of the Internet, much attractive local information appears. It describes good restaurants, public transportation, or the weather of the district. Though it is very useful in itself, if we want to complete some task such as business trip preparation, we must look for several information sites. But the access methods of the information and the formats of the output are different from each other. On the other hand, it became very easy to get electronic information on the outside of the town today. Because of the progress of the mobile terminal and the communication, we can get information even from the Internet. The mobile computing methodology and the service for utilizing the local information from the Internet is required. In this paper, we introduce Mobile Info Search (MIS), the research project and the implemented application of NTT Software Laboratories. The goal, the architecture, and the implementation of MIS are described. The goal of MIS is to collect, structure, and integrate the distributed and diverse local-information from the Internet in a practicable form and to provide it with a simple interface to the mobile user of various contexts. Though it is not easy to structure or integrate diverse information or to detect user's context, we do this in the location-oriented way. Local information and the mobile user have their own relevant location. We use this location information for the management and the integration in MIS. The concept and the architecture of MIS are described. MIS experiment is also implemented Internet application and has been open to public since September '97. MIS experiment has several features. (1) It has the location-oriented multi search that searches local information from external WWW database servers. It provides shop and sevices, maps, or public transportation information around the user's current location from the major Internet servers. (2) It has the location-oriented search engine for distributed WWW documents. It searches robot-collected information in the location-oriented structured way. It is named "kokono Search". (3) It has a simple interface to every information using latitude-longitude of the user's current location. PHS, GPS, and other devices are served for detection the user's location.
