How to use?

[inspire22]

Any suggestions how to use? I'm trying to do something like this
good_examples = ["happy birthday", "to you", "there boy"]
bad_examples = ["asdfasdfa", "asdfasdf"]

a = Hmm.new
a.train = (what here?)
a.classify "happy tuesday kevin" -> "good" (how to get results out?)

Thanks :)
