This library implements string similarity metrics.

StrSimError

Functions§

damerau_levenshtein
Like optimal string alignment, but substrings can be edited an unlimited number of times, and the triangle inequality holds.
hamming
Calculates the number of positions in the two strings where the characters differ. Returns an error if the strings have different lengths.
jaro
Calculates the Jaro similarity between two strings. The returned value is between 0.0 and 1.0 (higher value means more similar).
jaro_winkler
Like Jaro but gives a boost to strings that have a common prefix.
levenshtein
Calculates the minimum number of insertions, deletions, and substitutions required to change one string into the other.
normalized_damerau_levenshtein
Calculates a normalized score of the Damerau–Levenshtein algorithm between 0.0 and 1.0 (inclusive), where 1.0 means the strings are the same.
normalized_levenshtein
Calculates a normalized score of the Levenshtein algorithm between 0.0 and 1.0 (inclusive), where 1.0 means the strings are the same.
osa_distance
Like Levenshtein but allows for adjacent transpositions. Each substring can only be edited once.
