tional tendencies, intimacy and the attributes of initial disseminators in the communication process of public opinions, so as to conduct

targeted guidance and effective control of the diffusion of public opinions on social network platforms.【Method/process】Based on the

SIR model of infectious disease, this paper introduces the theory of emotional infection, constructs the transmission state with emotion⁃

al tendency, and considers the transmission difference of strong and weak relationship between friends, and introduces the intimacy

factor to dynamically design the interactive process of transmission. Combined with the design of weighted scale-free network topolo⁃

gy, the influence factors of the improved model are compared and analyzed.【Result/conclusion】The social network platform public

opinion communication model built by combining emotion and intimacy is more consistent with the real public opinion communication

process, and more targeted public opinion guidance and control Suggestions are proposed according to the parameter adjustment and

analysis of various influencing factors.【Innovation/limitation】Emotional factors and user relationship intimacy are introduced into the

communication of public opinion in this paper, and the interaction of emotional information among friends and its influence on the com⁃

munication are mainly considered. However, the reality communication environment is very complex, and the communication environ⁃

ment of public opinion and its influencing factors are still the key research direction of future research.
