damerau_levenshtein_normalized_distance: Normalized Damerau-Levenshtein Distance

In RapidFuzz: String Similarity Computation Using 'RapidFuzz'

Normalized Damerau-Levenshtein Distance

Description

Calculate the normalized Damerau-Levenshtein distance between two strings.

Computes the normalized Damerau-Levenshtein distance, where the result is between 0.0 (identical) and 1.0 (completely different).

Usage

damerau_levenshtein_normalized_distance(s1, s2, score_cutoff = 1)

Arguments

s1	A string. The first input string.
s2	A string. The second input string.
score_cutoff	An optional maximum threshold for the normalized distance. Defaults to 1.0.

Value

The normalized Damerau-Levenshtein distance as a double.

Examples

damerau_levenshtein_normalized_distance("abcdef", "abcfde")
damerau_levenshtein_normalized_distance("abcdef", "abcfde", score_cutoff = 0.5)
