The invention relates to a big data technology, and discloses a topic classification method, which comprises the steps of obtaining a bag-of-words model corresponding to each article in an informationbase, the bag-of-words model being a subject term combination formed after stop words and part-of-speech screening, and the bag-of-words model comprising subject terms and occurrence frequencies corresponding to the subject terms; taking the bag-of-words models corresponding to the articles as topics of the articles in a one-to-one correspondence manner, and inputting the bag-of-words models intoan LDA topic model; judging whether the iterative training process of topic classification of the topics of the articles is converged or not by the LDA topic model according to a preset topic number;and if yes, obtaining classification information of topic classification corresponding to each output article when LDA topic model training converges. Bag-of-words models respectively corresponding to articles are respectively formed after stop words and part-of-speech screening and serve as feature input of the LDA topic model, interference of words without content value and appearing at high frequency is avoided, and noise influence in the topic classification process is eliminated.
