Viral video: Describing online multimedia information flows
暂无分享,去创建一个
This paper examines why certain videos go viral while other languish and die. To answer this question metadata associated with YouTube videos was collected (over the course of three separate weeks in 2009) and analyzed. The results show that virality is intimately connected to how one defines popularity, as different components of the metadata highlight the importance of different sets of videos over time. For this reason different elements of the metadata are explored and examples are given from the dataset that indicate popularity.
