Towards Exploring the Influence of Community Structures on Information Dissemination in Sina Weibo Networks

Figure 1

Example of an IPT. The yellow root node is the user who posted the original message. Gray nodes are users who spread the information (propagation nodes) and green nodes indicate users who did not spread the information (terminal nodes) [20]. The directed arrows show information flows. Hence, an IPT is also a subgraph of the social networks formed by users, i.e., one of the subgraphs of the user’s circle of friends.
