Survey of text classification methods based on deep learning

Text classification is a research hot spot in the field of natural language processing, which is mainly used in public opinion detection, news classification and other fields. In recent years, artificial neural networks has good performance in many tasks of natural language processing, the application of neural network technology to text classification has also made many achievements. In the field of text classification based on deep learning, numerical representation of text and deep-learning-based text classification are two main research directions. The important technology of word embedding in text representation and the implementation principle and research status of deep learning method applied in text classification were systematically analyzed and summarized. And the shortcomings and the development trend of text classification methods in view of the current technology development were ana-lyzed.
