This study focuses on the online comments of Bilibili financial videos, aiming to analyze the content characteristics and user emotional tendencies of financial video comments through text mining techniques, and construct a video popularity evaluation model. The research methods include the LDA topic model, SnowNLP sentiment analysis, and TF-IDF feature extraction technology. Through systematic analysis of high-quality review data, this study reveals the impact mechanism of financial content dissemination and provides empirical evidence for creators to optimize content production, platforms to improve recommendation algorithms, and investors to grasp market sentiment. The research results indicate that positive emotions dominate in comments, and users hold an optimistic attitude towards the overall financial field, but remain vigilant about specific issues and potential risks. There are significant differences in emotional tendencies under different themes, and high-frequency word analysis reveals the dual psychology of users when discussing financial topics.
