Abstract  

[Objective] This paper proposes a new method to improve the classification accuracy of the Chinese news texts with the help of Deep Learning theory. [Methods] We first used the denoising auto encoder to construct a deep network to learn the zipped and distributed representation of the Chinese news texts. Second, we used the SVM algorithm to classify these news texts. [Results] As the number of samples expanding, the precision rate, the recall rate and the F value of the proposed method increased too. The results are better than those of the applications using the KNN, BP and SVM algorithms. The average precision rate was higher than 95%. [Limitations] The data size was relatively small, thus, the proposed method did not fully utilize the parallel data processing capacity of the deep learning technology. [Conclusions] The proposed method improves the performance of applications classifying Chinese news texts.
