Figure 2

Social network attention. We selected the 10 users as the representatives from the Gowalla_edges dataset. The ordinate represents the ID number of the person concerned and the abscissa coordinates the ID number of fans. As can be seen from the figure, the user whose ID number is 20 received more than 176 people’s attention, the highest degree of attention; and the user whose number is 10 only received the attention of 22 people. Figure 2(b) shows the trajectory of the 3 users (their user Id are 15, 16, and 20, respectively). The abscissa represents latitude, and the ordinate represents longitude.
