Fuzz

The seven scorers, all returning a similarity in [0, 100].

public static class Fuzz

Example — the base scorer on a typo.

using Lodestar.Fuzzy;

double score = Fuzz.Ratio("apple pie", "appel pie");  // => 88.88888888888889

Remarks — 100 is identical and 0 shares nothing; the scale is rapidfuzz's, and the values match it. They are double rather than int because rapidfuzz's are, and rounding them here would make a ported comparison disagree at the boundary of a cutoff.

The seven are one scorer applied to different things: Ratio compares the strings, PartialRatio the best window, the Token* family the words after sorting or setting, and the PartialToken* pair both transformations at once. WRatio chooses among them.

Applies to — net10.0, netstandard2.0.

Members

Member	What it does
Fuzz.PartialRatio	The best-matching window of the longer string.
Fuzz.PartialTokenSetRatio	Set comparison over the best window.
Fuzz.PartialTokenSortRatio	Sorted comparison over the best window.
Fuzz.Ratio	Edit-distance similarity over the whole of both.
Fuzz.TokenSetRatio	The words as sets, so extras stop counting.
Fuzz.TokenSortRatio	The words sorted, so order stops counting.
Fuzz.WRatio	Picks among the others by inspecting the input.
