A system for automatically correcting a mistaken geocoded location input. A wireless device such as a cell phone ranks possible location input based on edit distance, which is a confidence factor. If there is no perfect match, then a list of geocode options is returned, preferably sorted by the score. The closeness is derived by looking at the edit distance to go from the input to the matched address. Edit distance is defined herein as the number of insertion/deletion/replacement operations to go from input location to the possible matched location. In one embodiment, an option list, or pick list, may be provided based on an edit distance scoring system. The edit distance scoring system is preferably based on a number of keystrokes difference between the input location name and the possible matched location name. |
