Abstract: With the development of Internet and information technology, a large number of multi-label texts data quickly generated. In the text classification, how to determine the appropriate number of categories and how to identify the label of the textmore accurately is an urgent problem to be solved. The HL_LDA model proposed in this paper automatically determines the number of categories through the hierarchical Dirichlet process, and improves the quality of the classification by discovering the hierarchical information between labels of multi-label documents. The experimental results show that the evaluation of HL_LDA is superior to the existing method in precision and F1-score compared with the LDA- based and SVM-based methods on different types of data sets.
