Its about seeing if there are more tokens seen in spam that have never been seen in ham than the opposite. Unless I misunderstand your technique, tokens that have never, ever been seen are not considered at all. [As is indeed the case with Bayes, except for those Bayes classifiers that assign some arbitrary probability to never-before-seen tokens.] So it is, in fact, matching. It looks very much like Bayes to me except without the theoretical justification. Regards, Dianne.
