在线社交网络中的歧视性混合

Disassortative mixing in online social networks

Haibo Hu, Xiaofan Wang

摘要:

传统观点认为,社交网络表现出一种排斥混合模式,而生物和技术网络则表现出一种排斥混合模式。然而,近年来对在线社交网络的研究改变了这一普遍看法,许多在线社交网络呈现出分离或中性混合的特征。特别地,我们发现在线社会网络Wealink经历了从真实社交网络的度可变性特征到许多在线社交网络的度可变性特征的转变,并且这种转变可以通过我们提出的一个简单的网络模型来合理地解释。本文还讨论了网络的可拓性、聚类性和模块性之间的关系。

英文摘要:

The conventional wisdom is that social networks exhibit an assortative mixing pattern, whereas biological and technological networks show a disassortative mixing pattern. However, the recent research on the online social networks modifies the widespread belief, and many online social networks show a disassortative or neutral mixing feature. Especially, we found that an online social network, Wealink, underwent a transition from degree assortativity characteristic of real social networks to degree disassortativity characteristic of many online social networks, and the transition can be reasonably elucidated by a simple network model that we propose. The relations among network assortativity, clustering, and modularity are also discussed in the paper.
