A classification model for a relevant document using the multinomial model will be proposed. Rules for classification are extracted from a training dataset and the rules are aggregated by using the multinomial model. Unknown parameters of the multinomial distribution are estimated by using the iterative proportional fitting algorithm. Bayesian classification method is used for classification after estimating the population distributions. Simulation experiments show that the proposed method can be competitive with the well known other classification models when two populations are similar. Applications to the TREC Conference are discussed.
