Wikipedia is a popular web-based encyclopedia edited freely and collaboratively by its users. In this paper we present an analysis of Wikipedias in several languages as complex networks. The hyperlinks pointing from one Wikipedia article to another are treated as directed links while the articles represent the nodes of the network. We show that many network characteristics are common to different language versions of Wikipedia, such as their degree distributions, growth, topology, reciprocity, clustering, assortativity, path lengths, and triad significance profiles. These regularities, found in the ensemble of Wikipedias in different languages and of different sizes, point to the existence of a unique growth process. We also compare Wikipedias to other previously studied networks.
维基百科是一部广受欢迎的基于网络的百科全书，由用户自由协作编辑。在本文中，我们将多种语言的维基百科作为复杂网络进行分析。从一篇维基百科文章指向另一篇文章的超链接被视为有向链接，而文章则代表网络的节点。我们表明，维基百科的不同语言版本具有许多共同的网络特征，例如它们的度分布、增长、拓扑结构、互惠性、聚类性、关联性、路径长度和三元组显著性分布。在不同语言和不同规模的维基百科集合中发现的这些规律，表明存在一个独特的增长过程。我们还将维基百科与其他先前研究过的网络进行比较。
