Extracting Geographic Context from the Web: GeoReferencing in MyMoSe

Many Web pages are clearly related to specific locations. Identifying this geographic focus is the cornerstone of the next generation of geographic context aware search services. This paper shows a multistage method for assigning a geographic focus to Web pages (GeoReferencing), using several heuristics for toponym disambiguation and a scoring function for focus determination. We provide an experimental methodology for evaluating the accuracy of the system with Web pages in English and Spanish. Finally, we have obtained promising results, reaching an accuracy of over 70% with a town-level resolution.
