Never heard of it, but it appears pretty straightforward:

1.9.3 (main):0 > require 'stemmer'
=> true
1.9.3 (main):0 > "foobical".respond_to? "stem"
=> true
1.9.3 (main):0 > "foobical".stem
=> "foobic"
1.9.3 (main):0 > "canonical".stem
=> "canon"
1.9.3 (main):0 > "logical".stem
=> "logic"
1.9.3 (main):0 > "recreational".stem
=> "recreat"
1.9.3 (main):0 > "fictitious".stem
=> "fictiti"

How well it works for your purposes, I'll leave for you to decide :-)
