Abstract: With the ever-increasing number of digital documents, the ability to automatically

classify those documents both quickly and accurately is becoming more critical and difficult. A

text classification system for Chinese documents is developed in this paper. A HTF-WDF algorithm

is proposed for feature selection. Different from other feature selection algorithms, this method
