A correlithm object processing system includes a memory that stores a first string correlithm object comprising a first plurality of sub-string correlithm objects, and a second string correlithm object comprising a second plurality of sub-string correlithm objects. A string correlithm object engine communicatively coupled to the memory determines the anti-Hamming distances between each of the sub-string correlithm objects of the first string correlithm object pairwise with each corresponding sub-string correlithm object of the second string correlithm object, and stores the determined anti-Hamming distances in a distance table. The engine identifies a group of neighboring anti-Hamming distances stored in the distance table that are greater than a predetermined number of standard deviations beyond a standard distance and, in response, determines the corresponding sub-string correlithm objects of the first and second string correlithm objects to be a match.
