Abstract: In the new media environment, online rumors spread rapidly and have a wide range of influence, posing a serious threat to social stability and the credibility of public security organs. This paper takes the “Qin Lang’s homework lost in Paris” incident as a case study, using the LDA topic model to conduct text analysis on the relevant comments of the incident. Through information collection methods and topic modeling, it reveals the public opinion characteristics and dissemination patterns of online rumors. Based on this, it proposes a comprehensive governance strategy system for online rumors from six dimensions, including rumor verification, truth disclosure, and rumor elimination, providing theoretical basis and practical reference for public security organs to handle similar cases.
