Abstract:Through the Scrapy framework,the relevant Weibo blog posts and comments related to earthquake of magnitude 5.0 or above in China in the past three years (2021-2023) were obtained,and the crawled text data was preprocessed and compiled into a dataset,and a deep learning earthquake public opinion sentiment tendency model based on BERT and Long Short-Term Memory (LSTM) was designed. The results show that the accuracy of the model in the text sentiment analysis of earthquake public opinion reaches 97.8%,and it has efficient feature extraction ability,which can provide a reference for the monitoring of earthquake network public opinion.
