The WWW provides an overwhelming amount of information, which
spatially indexed can be a valuable additional data source for
location- based applications. By manually building a spatial index,
only a fraction of the available resources can be covered. This
paper introduces a system for the automatic mapping of web pages to
geographical locations. Our web robot uses several sets of domain
specific keywords, lexical context rules, that are automatically
learned, and a hierarchical catalogue of geographical locations that
provides exact geographical coordinates for locations. Spatially
indexed web pages are used to construct Geographical Web Portals,
which can be accessed by different location-based applications. In
addition, we present experimental results demonstrating the quantity
and the quality of automatically indexed web pages.
