== Problem ==
Although both papers study the popularity dynamics of user-generated videos, the focus is quite different. Paper 1 tries to characterize the evolution of YouTube video popularity in a general sense, while Paper 2 focuses on the content-agnostic factors only, and deliberately removes the impact that might be caused by video content. In paper 1, a three-phase evolution model is proposed to explain the popularity dynamics, while paper 2 does not have such characterization.

== Dataset==
Paper 1 uses a dataset tracking the views of recently uploaded YouTube videos over the duration of eight months. Paper 2 uses clone sets of videos to explicitly remove the content factors that might impact the popularity.

==Other==
Both papers were written by the same authors, and Paper 2 is a follow-up work of Paper 1 for specifically focusing on the content-agnostic factors.
