System and method for contextual and free format matching of addresses

Abstract

A system and method for the matching addresses is provided. Addresses may be received from a search engine or other source for purposes of matching. Address parts in the addresses may be contextually identified. Identified address parts, including their associated data, that have address part types that are alike may be compared to one another and a contextual matching score may be calculated and assigned. A free format token analysis of the addresses may also be performed in parallel with, before, or after, the contextual identification, and a free format matching score may be calculated. An address likeness score may be calculated and assigned based on the contextual matching score and the free format matching score.

1 . A method for matching a first address and a second address using a processor, the first address and the second address each associated with one or more individuals, the method comprising:
 receiving the first address and the second address at the processor;   contextually identifying a first address part of the first address and a second address part of the second address, using the processor, based on a deterministic evaluation of at least one string in each of the first address and the second address to identify the first address part and the second address part;   normalizing, using the processor, the first address part to produce a first normalized address part and the second address part to produce a second normalized address part;   comparing the first normalized address part and the second normalized address part, using the processor;   calculating a contextual matching score, based on comparing the first normalized address part and the second normalized address part, using the processor;   performing a free format token analysis of the first address and the second address, using the processor;   calculating a free format matching score, based on performing the free format token analysis of the first address and the second address, using the processor;   calculating an address likeness score, based on the contextual matching score and the free format matching score, using the processor; and   transmitting the address likeness score from the processor.
