Abstract
A computer implemented method for identifying and removing similar examination items in a digital examination includes obtaining, with an examination evaluation server, a digital examination with a plurality of examination items, tokenizing a first examination item of the plurality of examination items into a first set of n-grams, tokenizing a second examination item of the plurality of examination items into a second set of n-grams, generating a first item vector from the first set of n-grams, generating a second item vector from the second set of n-grams, generating multiple item congruence values for corresponding similarity dimensions by comparing the first item vector with the second item vector, and identifying that the first and second examination items are a potential enemy item pair if one or more of the item congruence values exceed corresponding threshold values.
