To review the character played from the circle build on meme diffusion procedure, we replicate the brand new model to your tested follower community (solid black range) and you can a random system (dashed red-colored range). (a) The word lives spends the latest times while the time product. (b,c,d) Meme prominence, associate hobby and you will member entropy analysis depend on weekly tips.
Whether or not present epidemiological models have begun as a result of the simultaneous give out of contending challenges 39,40 , our very own design ‘s the earliest just be sure to manage a near unbounded quantity of new “epidemics” which might be continuously inserted for the system
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 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.
