Dice’s coefficient (Dice 1945) or index is one classic measure of similarity between sets, which is widely used in the biological sciences. 33 is iffy. Once the n-grams have been established for two strings being compared, the calculation is completed using the following formula:. Edit distance is a large class of distance metric of measuring the dissimilarity between two strings by computing a minimum number of operations (from a set of operations) used to convert one string to another string.
