摘要 通过实证,分析了某高校BBS论坛不同时期的网络特征。BBS帖子网络是由两级节点树组成的森林,用户网络是一般形态的复杂网络,其中用户网络度分布服从广延指数分布。静寂期和活跃期用户网络的广延指数值会发生变化。实证结论表明BBS网络度分布不是严格的幂律分布,不同的BBS网络度分布特征存在差异;而且证实同一网络在不同时期的网络度分布特征也会发生变化。 Through analyzing a BBS forum networks,we find article networks are composed of growing tree with two-tier node and user networks are a general complex networks.User networks follow a stretch exponential distribution(SED).The indexes of SED of inactive days and active days are variable.This finding is inconsistent with existing results,which neither get religious nor precise results,some curves of degree distribution display the shape of SED.Finally we discuss the related issues of BBS forum networks,which is beneficial to realize the essence of BBS and Web users.
