Abstract

We have been developing a geographic Web search system to retrieve proper Web pages for a user-specified geographic area. One of location specification methods possible in the system is a two-dimensional range query, which is specified by a rectangle region corresponding to a geographic area. In order to handle such a geographic query, we propose: i) a geographic Web index method which is possible to manage each Web pages by optimized geographic scope; and ii) geometric operations such as ´Contain´ as a function to retrieve geographic Web pages. However, recall and precision of search results by raw geometric search operations become very low, if we do not optimize a geographic area to a Web page. By considering of geowords´ characterics, we can improve the result by geometric operations in range query processing.
