Abstract
A method for performing approximate string matching comprises: obtaining a predefined distance error threshold and user information, the user information including a list of strings; calculating distance metrics for pairs of strings in the list of strings; determining a positive list and a negative list based on the calculated distance metrics for the pairs of strings; determining histogram representations of the list of strings; determining true positive rates and false positive rates for one or more histogram thresholds based on the positive list, the negative list, and calculated histogram distances between pairs within the histogram representations; and obtaining an acceptable histogram threshold from the one or more histogram thresholds based on an acceptable true positive rate and an acceptable false positive rate.
