摘要
为了研究UGC视频的结构特点和组织形式,针对采集到的爱奇艺用户发布视频数据进行了测量,重点分析了视频在类别、时长、播放数和评论数等方面的特点以及它们之间的关系,发现了视频网络的小世界特性。通过结合节点度分布、网络社区划分K-core分层和Bow-tie模型等方面测量了基于订阅关系构成的用户关系网络的特性,发现了该网络的无尺度特性以及用户节点分布的特点,网络内部用户之间的联系并不紧密,但在该用户网络中有相当多的节点处于网络的核心层次。
In order to study the structural characteristics and organization of UGC video,with the measurement of the userpost video data,this paper analyzed the category of video,the video length,number of views and comments,got the statistical features and theirs relationship,it also found the small word properties of the video network. Then,it measured the user network based on subscription on degree distribution,community division,K-core delamination and Bow-tie model,found the scale-free property of the user network and the characteristics of user node distribution. The connection between users within the network is not close,but there are quite a number of nodes in the user network at the core level of the network.
