Abstract
A service for providing spatial information is increasing recently. This service is easily used by a personal computer or a mobile phone. It is important that a digital map has a lot of attributes on the spatial service. However, making attributes of digital maps requires a great deal of time and money. Therefore, it is difficult to define attributes of spatial data and to produce these values. The purpose of the present research is to develop a system that can produce and update automatically attributes of the digital map by searching them on web pages. Moreover, a function for searching spatial information with the keyword of natural language is implemented.
