Method of operating a navigation system to provide geographic location information
Abstract:
A computer implemented method of operating a navigation system to provide geographic location information is provided. The method comprises receiving a query text string representing a query for a geographic location from a user and obtaining data records that represent a plurality of candidate geographic locations. The method computes a text matching score that indicates how much of the query text string matches a record text string of the candidate geographic location and applies a usage pattern weight to the text matching score to obtain an overall score value for the candidate geographic location. The candidate geographic locations are ranked based on the overall score values.
