Fast-stemmer is simply a wrapping around multithreaded Porter stemming algorithm.

This gem adds a String#stem method, and it conflicts with the stemmer gem. It’s in order of magnitude faster (and uses much less memory) than the latter.

For the original work please see: tartarus.org/~martin/PorterStemmer/

Gemfile:

gem 'fast-stemmer'

Usage:

require 'rubygems'
require 'fast_stemmer'

Stemmer::stem_word('running') # -> 'run'
'running'.stem                # -> 'run'
