Abstract

This paper improves the naïve bayesian classification algorithm , combining with the rough set theory we can get a naive bayesian classifier algorithm based on the rough set. We implement this algorithm on a cloud platform using map-reduce programming mode and get a excellent result. A recall rate of 76.4 was achieved when classifying Tibetan Web pages .
