Stemming reduces related words to a common root form. for instance, "horse", "horses", and "horsing" all become "hors". most commonly, stemming is deployed as part of a search application, allowing searches for a given term to match documents which contain other forms of that term.
this module is very similar to lingua::stem|lingua::stem -- however, lingua::stem is pure perl, while lingua::stem::snowball is an xs module which provides a perl interface to the c version of the snowball stemmers. (http://snowball.tartarus.org).
