README
Text Metrics
The library provides efficient implementations of various strings metric
algorithms. It works with strict Text
values.
The current version of the package implements:
 Levenshtein distance
 Normalized Levenshtein distance
 DamerauLevenshtein distance
 Normalized DamerauLevenshtein distance
 Hamming distance
 Jaro distance
 JaroWinkler distance
 Overlap coefficient
 Jaccard similarity coefficient
Comparison with the editdistance
package
There is
editdistance
package
whose scope overlaps with the scope of this package. The differences are:
editdistance
allows to specify costs for every operation when calculating Levenshtein distance (insertion, deletion, substitution, and transposition). This is rarely needed though in realworld applications, IMO.editdistance
only provides Levenshtein distance,textmetrics
aims to provide implementations of most string metrics algorithms.editdistance
works onStrings
, whiletextmetrics
works on strictText
values.
Implementation
Although we originally used C for speed, currently all functions are pure Haskell tuned for performance. See this blog post for more info.
