Abstract A rumor spreading model for the web forum based on the heterogeneity of web forum user behaviors and SEIR model is proposed in this paper. First, according to the mean-field equations of the model on inhomogeneous networks, the critical threshold of the spreading of rumor is deduced, the result of theoretical analysis shows that the increase in trust mechanism between users can effectively inhibit the rumor spread in the network with limited velocity of propagation; Then the simulation and numerical analysis of the model itself and the influences of trust mechanism to the model is given, which verify the validity of the model and the introduction of trust mechanism can effectively reduce the rumor influence, the velocity of rumor spreading and the rumor size; Finally, combined with the previous conclusions and the high-influence limited trust relationships between web forum users, a high-influence immunization strategy is given. The experimental results show that the strategy able to reach better effect than traditional immunization strategy.
