Abstract
Disclosed is a system for, and method of, calculating parameters used to determine whether records and entity representations should be linked. The system and method use a symmetric and reflexive function to allow for linking records and entity representations whose field values differ. The system and method apply iterative techniques such that parameters from each linking iteration are used in the next linking iteration. The system and method need no human interaction in order to calibrate and utilize record matching formulas used for the linking decisions.
