ABSTRACT:
A method, apparatus, system, and storage medium that, in an embodiment, create an index for pages based on association scores for the pages with respect to geographic regions, where the association scores indicate relative degrees to which the pages are associated with the geographic regions. In an embodiment, the association scores are determined by adding a term scare to the association score if a term that is associated with the geographic region is present in the page. The term score indicates a relative degree to which presence of the term in the page indicates that the page is associated with the geographic region. In an embodiment, the association scores are further increased based on association scores of neighbor geographic regions and based on the association scores of incoming linked pages.
