Understanding User Generated Content Characteristics : A Hot-Event Perspective

Now-a-days, millions of Internet users watch and upload a large number of videos on User Generated Content (UGC) sites (e.g., Youtube) everyday. Moreover, online videos about hot events, such as breaking news and Olympic games, attract lots of users. In this paper, the authors study the characteristics of hot-event videos by collecting video traces of the largest UGC site in China for 28 days. They first empirically study statistical properties of such videos and find that hot-event videos contribute a large number of views, even though the total number of hotevent videos is relatively small. In addition, there exist extremely active uploaders and top 10% active uploaders upload over 60% videos.
