Systems, apparatus, and methods of programmatically determining unique contacts based on crowdsourced error correction

A computer-implemented method for improving accuracy of a match score algorithm comprising:

• determining a plurality of programmatic match results based at least in part on applying the match score algorithm on merchant data, wherein the match score algorithm indicates a match score threshold;
• determining a precision error rate and a recall error rate based at least in part on the plurality of programmatic match results and a plurality of user match results, wherein the plurality of user match results are based on user input;
• determining an estimated precision/recall error ratio based at least in part on the precision error rate and the recall error rate;
• determining an expected precision/recall error ratio associated with the plurality of programmatic match results;
• and
• implementing an optimization algorithm to incrementally adjust the match score threshold of the match score algorithm to minimize a difference between the estimated precision/recall error ratio and the expected precision/recall error ratio.
