Abstract  

[Objective] Study on an evolution model of microblog public opinion considering the influence of next-nearest neighbors. [Methods] Use the directed BA scale-free network to simulate the network formed by users' attention relationship in microblog, and design the iterative rule, in which the nearest and the next-nearest neighbors influence the microblog view evolution in combination. Then simulate the view evolution of microblog public opinion with or without the influence of next-nearest neighbors, and the opinion evolution under different review probabilities and different forwarding probabilities. [Results] Considering the influence of next-nearest neighbors on view evolution, it would take less time to reach an agreement for microblog users. The experiments show that the behaviour of review increases the relaxation time of opinion evolution, but the behaviour of forwarding shortens it. [Limitations] The model highlights the effect of next-nearest neighbors on the opinion evolution of microblog public opinion and does not account for other factors such as the social environment. [Conclusions] The evolution model of microblog public opinion considering the influence of next-nearest neighbors can characterize the opinion evolution of microblog public opinion in a more realistic way. The simulation results show that microblog plays a role in aggregating the public opinion in a short time period and easily causes public pressure.
