Information Dissemination Model and Trend Forecast of Short Video Social Network

With the advent of big data era, short video social network has gradually become an important battlefield for the outbreak of online public opinion. Therefore, the study for information transmission model is a hot topic for governing online public opinion. Based on improving the shortcomings of traditional SEIR model, we establish the BLSI model. Furthermore, the main affecting factors of information dissemination are selected by the principal component analysis method. Through changing the value of model parameters, the processes of information dissemination are simulated under different conditions. The simulation results are similar to the real network.
