“…For example, in Ren et al [21], the authors point out that the online popularity is a significant effecting factor on videos in online systems; in Iveroth et al [22], competitors' price is a base factor for deciding; in Choi et al [23], they imply that discount on price can have effect on the sales of information goods; in another study, Niu and Li [24] suggest for the Internet service providers a price model depending on the congestion of Internet. (ii) Model validation: our time-continuous model should fit the data collected in real world, identify model coefficients, and validate other sets of data.…”

“…And our results also show that the users' choice of different types of online contents are not only affected by a simply factor, thus considering the different properties among different populations, and analyzing separately if possible are necessary for accurate prediction of the growth. However, on the one hand, we would enhance our model to regenerate the long-term popularity of online objects [37] and consider more popularity mechanisms from the perspective of social system in our future works, such as community [38][39][40], trust relationship, and friend relationship, and so on. On the other hand, the potential factors on Apps' becoming popular is still a meaningful field to improve the popularity of online objects.…”

“…Degree Increase (DI): The time information is often overlooked in the evolution of complex networks. In fact, time plays a crucial role in the evolution of information networks [31,32,33]. The combination of recommendation systems with time dynamics improve the recommendation and allows to perform better predictions.…”
