GENERATING A RANKED LIST OF BEST FITTING PLACE NAMES

摘要

A method of updating a plurality of databases storing place names includes collecting first, second and third coordinates of addresses including a first, a second and a third place name, respectively, clustering the first, second and third coordinates in a first, a second and a third cluster, respectively, obtaining a base address including the first place name and having base coordinates, assessing the best fit of the base coordinates to the first, second, and third clusters, and based on the two best fit clusters, identifying the second or third place name as an alias place name for the first place name. The method further includes obtaining alias addresses including the alias place name, fuzzy matching the base address to an alias address, and updating first and second databases by linking the alias address in the second database to the base address in the first database.
