The general procedure of the IPT null model for different topics of information propagation. The left is the original IPT, and the right is the corresponding randomized copy of the IPT. The core of the edge rewiring strategy is to keep the nodes of each layer of the IPT unchanged, and then, the upper node of the two adjacent layers selects a node from the lower layer according to the probability shown in equation (3) and then establishes a directed edge.
