This module contains functions to calculate the Sorensen-Dice coefficient of 2 given strings.

Summary

Functions

compare(a, b)

Calculates the Sorensen-Dice coefficient of two given strings with the ngram size set to a default value of 2.

compare(a, b, ngram_size)

Calculates the Sorensen-Dice coefficient of two given strings with a specified ngram size passed as the third argument.
