Abstract: This paper presents a Chinese-text classifier based on vector space model. Some key techniques implemented in this classifier, such as feature extraction, dimension reduction, hierarchical classification and classifier training, are discussed in details. As experiment results show, the developed system can reach both high precision and high recall on average.
