A collection of text algorithms.

Usage

require 'text'

Levenshtein distance

Text::Levenshtein.distance('test', 'test')
# => 0
Text::Levenshtein.distance('test', 'tent')
# => 1
Text::Levenshtein.distance('test', 'testing')
# => 3
Text::Levenshtein.distance('test', 'testing', 2)
# => 2

Metaphone

Text::Metaphone.metaphone('BRIAN')
# => 'BRN'

Text::Metaphone.double_metaphone('Coburn')
# => ['KPRN', nil]
Text::Metaphone.double_metaphone('Angier')
# => ['ANJ', 'ANJR']

Soundex

Text::Soundex.soundex('Knuth')
# => 'K530'

Porter stemming

Text::PorterStemming.stem('abatements')  # => 'abat'

White similarity

white = Text::WhiteSimilarity.new
white.similarity('Healed', 'Sealed')   # 0.8
white.similarity('Healed', 'Help')     # 0.25

Note that some intermediate information is cached on the instance to improve performance.

Ruby version compatibility
