RE: [Classifier4j-devel] Bayesian Case Study

[Matt C. <MCo...@my...>]

Attached are input and output files from the snowball stemmer.  Clearly need 
to remove punctuation before stemming with this one.  Does this look OK?

Anybody know why these stemmers like using input strings and single character 
inputs.  How do we quickly and easily send a string to this class?
