An information dissemination model based on positive and negative interference in social networks

Considering that information dissemination in social networks will be affected by external factors, this paper proposes a new PaNSEIR (positive and negative susceptible exposed ignorant removal) model. The model first introduces the information interference function to describe the influence of external information. Then combines the complex network theory and the propagation dynamics theory to establish a dynamic equation of information propagation. Finally, the model is applied to Twitter and Sina Microblog for simulation and compared with the traditional SEIR model. The simulation results demonstrate that external information interference will greatly promote the dissemination of the original information. The comparison with the SEIR model shows that the PaNSEIR model can better reflect the characteristics of information dissemination in real social networks, proving that the proposed information dissemination model is both reasonable and effective. This model is helpful in understanding the spread of information in social networks and provides ideas for studying the impact of external interference on the spread of information in social networks in the future.

Automated summary

This study introduces a new information dissemination model, the PaNSEIR model, which simulates the spread of information in social networks by incorporating an information interference function and combining complex network theory and propagation dynamics theory. The results show that external information interference promotes the dissemination of original information, and the model can better reflect the characteristics of information dissemination in social networks.
