维基百科中跨语言链接的无标度拓扑
Scale-free topology of the interlanguage links in Wikipedia
摘要：
维基百科中的跨语言链接连接了以不同语言编写的同一主题的页面。从理论上讲，每个连接的组件应该是一个集团，并涵盖一个主题。然而，不连贯的编辑和明显的错误导致主题合并，产生本文研究的非平凡拓扑。我们表明，组件的大小分布服从幂律，我们解释异常的分布作为某些编辑约定的结果。接下来，我们提出了一种过滤掉集团的方法，并研究了所得到的骨架的基本性质，结果证明是无标度的。
英文摘要：
The interlanguage links in Wikipedia connect pages on the same subject written in different languages. In theory, each connected component should be a clique and cover one topic. However, incoherent edits and obvious mistakes result in topic coalescence, yielding a non-trivial topology that is studied in this paper. We show that the component size distribution obeys the power law, and we explain anomalies in the distribution as results of certain edit conventions. Next, we propose a method of filtering out the cliques and study basic properties of the resulting skeleton, which turns out to be scale-free.
