In the field of NLP, pre trained models greatly shorten development time, reduce usage difficulty, and improve model robustness. In this paper, the BERT pre training model is used to analyze the text emotion of Tiktok short video comments. Through experimental comparison, it is found that the BERT pre training model is better than CNN and BiLSTM in emotion classification. Based on the BERT model, the multi strategy hybrid method is used to further input the BERT output dynamic word vector into the CNN and BiLSTM models to further extract local features and features with long distance dependency, improve the accuracy of the model, and obtain a good classification effect on the government short video comment dataset, which is better than the single model.
