Agent-Based Simulation of Rumor Propagation on Social Network Based on Active Immune Mechanism

, 2017
To simulate the rumor propagation process on online social network during emergency, a new rumor propagation model was built based on active immune mechanism. The rumor propagation mechanisms were analyzed and corresponding parameters were defined.
