Abstract
A navigation system includes a control unit configured to identify map data for a geographic region; generate an n-gram frequency set based on the map data and the geographic region; calculate a target occurrence rate for detecting one or more potential spelling errors in the map data based on the n-gram frequency set; and a communication interface, coupled to the control unit, and configured to communicate the target occurrence rate.
