title: Word categorization with weka
body: <p>Can Weka's Naive Bayes be used to categorize words?
  For example, I have this training data:</p>
  
  <p>great - P<br>
  bad - N<br>
  good - P<br>
  thanks - P<br>
  ...</p>
  
  <p>Can I use a Naive Bayes classifier to categorize new words?<br>
  Like this:<br>
  aweful - N</p>
