Research on Modeling and Simulation of Information Cocoon Based on Opinion Dynamics

In order to excavate the internal mechanism of information cocoon, according to the theory of system science, the paper built information cocoon model from the perspective of opinion dynamics and the model was simulated by NetLogo. Based on community structure, the study set the interaction background, which introduced the trust threshold between communities, so that different communities could interact with each other according to certain threshold. The different values of different communities are expressed by the difference of trust thresholds inside and outside communities. The simulation results show that information cocoon exist and have deep and shallow levels; Increasing the tolerance of communication with heterogeneous communities has a positive effect on restraining cocoon; To establish a mechanism to increase the connection between heterogeneous communities is helpful to inhibit the occurrence of cocoon phenomenon; The opinion tends to be close to the mainstream opinion in the final state, and targeted “cocoon-breaking” measures have been proposed.
