Abstract: A method for processing two different types of geographic address data sets to establish candidate matched data includes entering address data into the system and accessing a point level address data set. A determination is made if the point level data set contains an exact match to the entered address data. Any exact address data match from the point level data set is output. Candidate address data matches from the point level data set are saved when no exact match is determined as existing in the point level data set. A centerline address data set is accessed and a determination is made of candidate address data matches from the centerline address data set. Candidate address data from both the point level data set and the centerline data set are scored and matched. A system for geocoding and address hygiene includes a processing system with an input and an output system coupled to said processing system. A point level data set is coupled to the processing system.

Abstract: A method of interfacing data entry to an address matching engine includes of entering into a client processing system browser locale data for an address and entering into the client processing system browser an alphanumeric value of the street portion of said address. The client processing system sends to a web service after each entry of an alphanumeric value of the street portion of the address, the entered locale data and the entered alphanumeric street portion of the address. At the web service based on the entered locale data and the entered alphanumeric street portion of the address, searching is implemented for potential address matches. Any potential address matches obtained by the web service are returned from the web service to the client processing system in such a manner that any address matching session is maintained on the client processing system.
