Abstract

Abstract: Since the beginning of 2020, a novel coronavirus pneumonia (COVID-19) has gradually broken out, causing widespread concern from all walks of life. Aiming at Zhihu, the largest topic discussion platform in China, this study uses LDA (Latent Dirichlet Allocation) model to analyze the content and intensity evolution of the online discussion topics and to explore the changes of public opinion topics and their concerns during the epidemic. This experiment has a positive reference value for the supervision of epidemic information, and also has a learning and reference significance for the response and handling of public health emergencies in the future.

Key words: COVID-19, Public health emergency, Thematic evolution, Zhihu, Online public opinion, LDA model
