A collection of text algorithms.
require 'text'
Text::Levenshtein.distance('test', 'test') # => 0 Text::Levenshtein.distance('test', 'tent') # => 1
Text::Metaphone.metaphone('BRIAN') # => 'BRN' Text::Metaphone.double_metaphone('Coburn') # => ['KPRN', nil] Text::Metaphone.double_metaphone('Angier') # => ['ANJ', 'ANJR']
Text::Soundex.soundex('Knuth') # => 'K530'
Text::PorterStemming.stem('abatements') # => 'abat'

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.
The library has been tested on Ruby 1.8.6 to 1.9.3 and on JRuby.
