Dynamic Threshold-Based Records Linking

A computer system for records linking, the computer system comprising:

• a bus system;
• a storage device connected to the bus system, wherein the storage device stores program instructions;
• and
• a processor connected to the bus system, wherein the processor executes the program instructions to:
• select two records from a plurality of records corresponding to a customer for pair-wise record comparison;
• determine whether the two records are included in different entities;
• identify a local auto-link-threshold value of the different entities in response to the computer determining that the two records are included in different entities;
• perform an attribute comparison between the two records;
• generate a comparison score based on the attribute comparison between the two records;
• determine whether the comparison score is greater than the local auto-link-threshold value of the different entities;
• and
• link the two records in response to the computer determining that the comparison score is greater than the local auto-link-threshold value of the different entities.

A computer program product for records linking, the computer program product comprising a computer-readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method of:

• selecting, by the computer, two records from a plurality of records corresponding to a customer for pair-wise record comparison;
• determining, by the computer, whether the two records are included in different entities;
• identifying, by the computer, a local auto-link-threshold value of the different entities in response to the computer determining that the two records are included in different entities;
• performing, by the computer, an attribute comparison between the two records;
• generating, by the computer, a comparison score based on the attribute comparison between the two records;
• determining, by the computer, whether the comparison score is greater than the local auto-link-threshold value of the different entities;
• and
• linking, by the computer, the two records in response to the computer determining that the comparison score is greater than the local auto-link-threshold value of the different entities.
