学生交往虚拟网络中的小群体结构分析

手机短信作为简便有效的信息交流方式已成为大学生之间一种主要的交往形式。通过对2004.1~2004.7期间山东某学院在校学生手机短信通讯数据的统计分析，构建出学生人际交往虚拟网络，着重于网络拓扑结构的小样本统计分布研究，给出一种获取小群体拓扑结构的新算法。

Analysis on topology structure of students' interpersonal transaction networks

Short-message is an effective supplement and extension to network communication.The Students' Interpersonal Transaction Networks were investigated by using real datasets in Shandong University of Technology during 2004.1~2004.7.This research mainly investigated the Topology Structure of the Students'Interpersonal Transaction Networks,such as clustering coefficient and large-scale character. A novel method of community detection that was computationally inexpensive and possessed physical significance to a member of network was proposed.
