dice-similarity-coeff

The Dice Similarity Coefficient is a simple and elegant way to calculate a measure of the similarity of two strings. The values produces are bounded between zero and one.

The algorithm works by comparing the number of identical character pairs between the two strings.

Examples

import dsc from 'dice-similarity-coeff';
        

dsc.twoStrings('hello world','hello es6')
// 0.5
dsc.twoStrings('hello world','hello world!')
// 0.9473684210526315
dsc.twoStrings('google','facebook')
// 0.16666666666666666
dsc.twoStrings('github','microsoft')
// 1 (it is just joke result = 0)
dsc.simSort('hello',['hella','world','helloo','hel'])
