摘要
探索信息在微博客网络中的传播特点,为评价微博客信息影响力提供建议。采用数据挖掘的方法,对330条新浪微博样本的传播情况进行了整理和分析,通过绘制转发数—时间曲线展现信息的生命周期特征,从而归纳出三种典型的传播规律:单点传播、接力传播和病毒传播。结合信息在微博客网络中的传播特点,有针对性地提出了信息影响力评价指标,分别从持续影响力、吸引力、时效性、名人关注度等维度评价一条微博的质量。
The objective of this study is to explore the transmission characteristics of micro-blog messages and to provide suggestions on how to evaluate the influence of micro-blog messages. 330 messages were collected from Sina Weibo, and by drawing life cycle plots, messa- ges were classified into three categories of transmission characteristics： single transmission, relay transmission, and virus transmission. Ac- cording to the transmission characteristics, indexes were provided for each type of messages in order to evaluate the influence, attractive- ness, limitation period and popularity of the information.
