| 摘 要： | 回顾了最近有关在线人类行为动力学重要的实证结果:在线行为的时间间隔分布的肥尾特征.通过博客发文与维基修改记录等在线行为数据的实证结果,阐述了时间间隔分布的幂指数随着活跃性减小而递减的关系;进一步强调了在不同时间尺度上人类行为的时间间隔分布表现出来的异质性;最后总结和展望了这些特性对于未来研究在线群体演化的重要意义.

| Abstract: | The main result arising from recent studies on on-line human dynamics was reviewed.It concluded that the human activity has the heavy-tailed nature.Based on the empirical evidence from Blog-posting and Wiki-revising,it could be found that the distributions of the interevent timeτdecay powerlike asτincrease at both individual and population levels.Furthermore,time scales and obtain heterogeneous decay exponents in the intra- and inter-day range were pointed out.In the end,the significance of these features for the further research on the evolution of its group was emphasized. |
