1. A method for automatically determining if a location is a standalone location that can be identified by a name for the location, comprising: determining a name score for the location by determining an approximate number of pages that contain the name; generating a signature that includes the name for the location and an additional location specifier; determining a signature score for the location by determining an approximate number of pages that include the signature; and determining whether the location is a standalone location based on the name score and the signature score for the location by: computing a ratio of the signature score to the name score; if the ratio is greater than or equal to a standalone threshold value, determining that the location is a standalone location; and otherwise, determining that the location is not a standalone location.
