(A) Net1 (node’s degree > 1, edge’s weight > 100); (B) Net2 (node’s degree > 1, edge’s weight > 100). Nodes represent emojis, the size of the node represents the node’s weighted degree, and the colour of the node distinguishes different communities. The thickness of the edge represents the edge’s weight, i.e., the co-occurrence frequency between two nodes
