Source Description-Based Approach for the Modeling of Spatial Information Integration

Rapid development of information technology such as mobile terminals and GPS systems enabled information services that provide location-oriented information based on users’ positions. In this paper, we propose an approach for the modeling of information integration applications that incorporate spatial information sources in addition to conventional information sources to provide appropriate location-oriented information to users. First, we present our approach to the modeling of spatial information sources based on the source description framework. It provides a way to represent the content and the query capability of a spatial information source in a descriptive manner. Then we show a query processing scheme that finds a combination of information sources to respond to given queries and to evaluate them efficiently.
