Abstract: 【Purpose/significance】In order to identify the interactive dissemination rules of multiple public opinion topics in microblog and make the intervention decisions more pertinently,an interactive dissemination model of public opinion topics under multiagent intervention is proposed【. Method/process】This model integrates multiple interventions of Internet media and government,consid⁃ers the characteristics of unequal competition of multiple public opinion topics,and could analyze the intervention measures from the global perspective of the interactive dissemination.【Result/conclusion】Simulation experiments show that the proposed model could well simulate the evolution of interactive dissemination of multiple public opinion topics on micro-blog. In the process of multi-topic
interactive dissemination, the governance effect of public opinion under multi-agent intervention is better. Intervention decisionmaking should not only focus on a single public opinion topic,but should take comprehensive consideration of multiple public opinion topics and their interaction.【Innovation/limitation】This paper explores the interactive dissemination process of public opinion topics under multi-agent intervention by means of mathematical modeling,which provides a new perspective for the formulation of the super⁃visory control strategy of micro-blog. Future studies can be analyzed by combining relevant examples to further enrich and deepen re⁃search conclusions.
