Probably one potential problem would be the splitting of a string into words. A minor problem is that of figuring out what a "word" is, i.e. the division between words.

Otherwise looks like a pretty standard Bayesian analysis, which I believe pg has done already.

Not really. It's a simple regexp that Norvig uses.

Python:

  def words(text): return re.findall('[a-z]+', text.lower())
Arc:

  (def words (text) (tokens (downcase text) [~<= #\a _ #\z]))
