中文摘要：

这份报纸在一个公告牌系统(BBS ) 被奉献给分析和模型用户读物和答复活动社会网络。由从一个著名中国 BBS 社会网络分析数据集合，我们显示出一些用户活动怎么散布，并且揭示可能描绘用户动力学的几个重要特征。我们建议一个方法在 BBS 社会网络为用户活动建模。模型能同时复制用户活动的幂定律和 non-power-law 分布。我们的结果证明那用户读物和答复活动能通过简单基于代理人的模型被模仿。明确地， BBS 服务器怎么在网 2.0 申请与因特网用户一起交往，用户们怎么，并且怎么组织他们的读的表的礼貌行为的特点散布的用户是在活动模式的形成的重要因素。

英文摘要：

This paper is devoted to analyze and model user reading and replying activities in a bulletin board system （BBS） social network. By analyzing the data set from a famous Chinese BBS social network, we show how some user activities distribute, and reveal several important features that might characterize user dynamics. We propose a method to model user activities in the BBS social network. The model could reproduce power-law and non-power-law distributions of user activities at the same time. Our results show that user reading and replying activities could be simulated through simple agent-based models. Specifically, manners of how the BBS server interacts with Internet users in the Web 2.0 application, how users organize their reading lists, and how user behavioral trait distributes are the important factors in the formation of activity patterns.
