distanceJaroWinkler

strings.js:601

Compute the the Jaro Distance between two sequences (string or array) s1 and s2, using strict equality operator ===.

function MMO.core.strings.distanceJaroWinkler(a, b)

Espace de noms: MMO.core.strings

TIP: use with utf8Split to compare utf-8 strings Jaro distance formula: `dj = 1/3 * (m/|s1| + m/|s2| + (m-t)/m)` - dj is the Jaro distance - m is the number of matching characters (identical and the distance between them is < max(|s1|,|s2|)/2 - 1) - t is half the number of transpositions (compare the i-th character of s1 and the i-th character of s2 divided by 2) - |s1| is the length of the first string - |s2| is the length of the second string The Jaro-Winkler similarity uses a prefix scale p which gives more favorable ratings to strings that match from the beginning for a set prefix length l. p is a constant scaling factor for how much the score is adjusted upwards for having common prefixes. The standard value for this constant in Winkler’s work is p=0.1. l is the length of the common prefix at the start of the string (up to a maximum of 4 characters). Jaro-Winkler distance formula: `dw = dj + (l*p*(1-dj))` dj = (⅓) ( 6/6 + 6/6 + (6–1)/6) = ⅓ 17/6 = 0,944 = 94,4% l = 3 (which refers to “mar”). p = 0.1 (standard value) dw = 0,944 + ((0,1*3)(1–0,944)) = 96,1%
