Rules generated from moreover corpus have the form of: rule: [cat1: probability, cat2: probability, ....] The current algorithm implemented in ruleClassify chooses highest weighed category which is incorrect. The correct formulation of probability for a given cat C is below: P(C| R1 & R2 & R3) = P(R1|C) * P(R2|C) * P(R3|C) * P(C) / (P(R1) * P(R2) * P(R3)) Then all C above particular threshold are chosen, OR the most probable category is chosen. Either algorithm is worth testting

This procedure does not seem to be necessary as simple selection of rules with precision above 85% seems to provide good overall precision recall in folding scenario. Suggest putting it on back burner
