fuzzystrings.netstandard

Contains the (almost umodified) code of DuoVia.FuzzyStrings but with multiple build targets for both net40 and netstandard16. Compatible with dotnet classic and dotnet core frameworks. Furthermore the Levenshtein algorithm has been fixed, since the original implementation computed a wrong Levenshtein distance in some cases.

A Collection of Fuzzy String Algorithms for .NET.

This is partially derived from multiple open sources. See individual algorithm classes for attribution.

A developer may wish to take advantage of one or more of the algorithms included in this libray or on the contrived string comparison extension methods like this:

bool isEqual = input.FuzzyEquals(name);
double coefficient = input.FuzzyMatch(name);

Included Algorithms

Dice Coefficient based on bigrams

A good value would be 0.33 or above, a value under 0.2 is not a good match, from 0.2 to 0.33 is iffy.

Levenshtein Distance algorithm with transposition

A value of 1 or 2 is okay, 3 is iffy and greater than 4 is a poor match

Longest Common Subsequence

A good value is greater than 0.33.
