Expand description

This library implements string similarity metrics.

Enums§

Functions§

  • damerau_levenshtein
    Like optimal string alignment, but substrings can be edited an unlimited number of times, and the triangle inequality holds.
  • generic_damerau_levenshtein
    Like optimal string alignment, but substrings can be edited an unlimited number of times, and the triangle inequality holds.
  • generic_hamming
    Calculates the number of positions in the two sequences where the elements differ. Returns an error if the sequences have different lengths.
  • generic_jaro
    Calculates the Jaro similarity between two sequences. The returned value is between 0.0 and 1.0 (higher value means more similar).
  • generic_jaro_winkler
    Like Jaro but gives a boost to sequences that have a common prefix.
  • generic_levenshtein
    Calculates the minimum number of insertions, deletions, and substitutions required to change one sequence into the other.
  • 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.
  • sorensen_dice
    Calculates a Sørensen-Dice similarity distance using bigrams. See https://en.wikipedia.org/wiki/S%C3%B8rensen%E2%80%93Dice_coefficient.
