The stemming process is an algorithm to allow one to find the stem of an word (not the root of it). For further reference on stem vs. root, please check wikipedia articles on the topic:

• en.wikipedia.org/wiki/Stem_%28linguistics%29

• en.wikipedia.org/wiki/Root_%28linguistics%29

• Open issues

• Release Windows Gem

• Fork the project from github

• Make your feature addition or bug fix

• Add tests for it. This is important so I don’t break it in a future version unintentionally.

• Commit, do not mess with rakefile, version, or history.

  if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull

• Send me a pull request. Bonus points for topic branches.

• stemmer4r (ext)

• fast-stemmer (ext)
