To study the brand new role starred by community construction in the meme diffusion techniques, we simulate the brand new design to your tested follower community (solid black colored line) and you will an arbitrary circle (dashed red-colored line). (a) The expression lifestyle uses the fresh times as day equipment. (b,c,d) Meme popularity, member hobby and user entropy analysis derive from weekly steps.
Even though latest epidemiological patterns have started because of the multiple pass on off contending stresses 39,40 , the build is the very first just be sure to manage a virtually unbounded quantity of the fresh “epidemics” that will be continuously inserted toward program
The second key ingredient of our model is the competition among memes for limited user attention. To evaluate the role of such a competition on the meme diffusion process, we simulated variations of the model with stronger or weaker competition. This was accomplished by tuning the length tw of the time window in which posts are retained in an agent’s screen or memory. A shorter time window (tw < 1) leads to less attention and thus increased competition, while a longer time window (tw > 1) allows for attention to more memes and thus less competition. As we can observe in Fig. 7, stronger competition (tw = 0.1) fails to reproduce the large observed number of long-lived memes (Fig. 7(a)). Weaker competition (tw = 5), on the check this link right here now other hand, cannot generate extremely popular memes (Fig. 7(b)) nor extremely active users (Fig. 7(c)).
To study the role of meme competition, we simulate the model on the sampled follower network with different levels of competition; posts are removed from screen and memory after tw time units. We compare the standard model (tw = 1, solid black line) against versions with less competition (tw = 5, dot-dashed magenta line) and more competition (tw = 0.1, dashed red line). (a) The definition of lifetime uses the week as time unit. (b,c,d) Meme popularity, user activity and user entropy data are based on weekly measures.
