False information propagation control method based on key node propagation risk analysis

The invention discloses a false information propagation control method based on key node propagation risk analysis, and the method comprises the steps: achieving the representation of user node false information propagation behaviors and time dimensions through considering the diversity and complexity of a false information propagation feature space, constructing a propagation risk index calculation model, achieving the division of propagation risk levels, and achieving the calculation of the propagation risk levels. And on this basis, an improved discrete particle swarm optimization algorithm fused with an adaptive weighting strategy is designed and is used for searching a plurality of key propagation nodes with influence in a propagation risk node set, so that large-scale propagation control of false information is realized for the key propagation nodes. By the adoption of the false information propagation control method based on key node propagation risk analysis, large-scale propagation control over the f
