Matching objects using keys based on match rules
First Claim
1. A system for matching objects using keys based on match rules, the apparatus comprising:
- one or more processors; and
a non-transitory computer readable medium storing a plurality of instructions, which when executed, cause the one or more processors to;
generate a match rule key based on a match rule, wherein the match rule specifies whether two objects match;
create a plurality of candidate keys by applying the match rule key to a plurality of data objects;
create a probe key by applying the match rule key to a probe object;
determine whether the probe key matches a candidate key of the plurality of candidate keys;
determine whether the probe object matches a candidate object based on applying the match rule to the probe object and the candidate object in response to a determination that the probe key matches the candidate key corresponding to the candidate object; and
identify the probe object and the candidate object as matching based on the match rule in response to a determination that the probe object matches the candidate object, the match rule identifying a match of the probe object and the candidate object unless both the probe object and the candidate object have corresponding non-empty fields that lack a match.

Abstract
Matching objects using keys based on match rules is described. A system generates a match rule key based on a match rule, wherein the match rule specifies whether two objects match. The system creates candidate keys by applying the match rule key to data objects. The system creates a probe key by applying the match rule key to a probe object. The system determines whether the probe key matches a candidate key. The system determines whether the probe object matches a candidate object based on applying the match rule to the probe object and the candidate object if the probe key matches the candidate key corresponding to the candidate object. The system identifies the probe object and the candidate object as matching based on the match rule if the probe object matches the candidate object.

7. A computer program product comprising computer-readable program code to be executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code including instructions to:
-
generate a match rule key based on a match rule, wherein the match rule specifies whether two objects match; create a plurality of candidate keys by applying the match rule key to a plurality of data objects; create a probe key by applying the match rule key to a probe object; determine whether the probe key matches a candidate key of the plurality of candidate keys; determine whether the probe object matches a candidate object based on applying the match rule to the probe object and the candidate object in response to a determination that the probe key matches the candidate key corresponding to the candidate object; and identify the probe object and the candidate object as matching based on the match rule in response to a determination that the probe object matches the candidate object, the match rule identifying a match of the probe object and the candidate object unless both the probe object and the candidate object have corresponding non-empty fields that lack a match. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method for matching objects using keys based on match rules, the method comprising:
-
generating a match rule key based on a match rule, wherein the match rule specifies whether two objects match; creating a plurality of candidate keys by applying the match rule key to a plurality of data objects; creating a probe key by applying the match rule key to a probe object; determining whether the probe key matches a candidate key of the plurality of candidate keys; determining whether the probe object matches a candidate object based on applying the match rule to the probe object and the candidate object in response to a determination that the probe key matches the candidate key corresponding to the candidate object; and identifying the probe object and the candidate object as matching based on the match rule in response to a determination that the probe object matches the candidate object, the match rule identifying a match of the probe object and the candidate object unless both the probe object and the candidate object have corresponding non-empty fields that lack a match. - View Dependent Claims (14, 15, 16, 17)
