In this paper, disadvantages of algorithm for constructing decision tree based on positive region are analyzed. Aiming at these disadvantages, a new algorithm for decision tree based on positive region and its classification ability is proposed. The method is simple and easy- to- understand. The example shows that the method is effective.
