The cognitive significances of geographic objects play an important role in optimizing a set of place names presented on a map interface. The aim of this research is to assign a value for cognitive significance to each place name in GIS, based on regional documents collected from the Web. The assigned values could be used in GIS applications including regional information searches, path findings, and car navigation systems. We will compare different criteria for cognitive significance and discuss a system already in use, before presenting our experimental results.
