维基百科链接网络实证分析

Structural analysis on Wikipedia linkage network

理解维基百科词条链接网络的结构特征是深入而有效地应用维基百科的前提。基于2010年1月的数据,从度分布、权分布、宏观结构特征等角度对维基百科词条链接网络的结构特征展开实证分析。相关结果与2006年之前的维基百科词条链接网络展开对比,发现当前的维基百科网络仍然具有无标度网络特性;其宏观结构总体上满足bow-tie模型,但模型中的各组成部分比例发生了显著变化。因此,该研究对深入解析维基百科词条链接网络的结构特性具有理论和现实意义。

In order to make better use of Wikipedia,it is necessary to have a clear understanding of the structural features of word entry hyperlink network of Wikipedia.This paper conducted brief experimental analysis in aspects of degree distribution,weight distribution and marco structural analysis on Wikipedia crawled on January 2010.By comparing these characteristic with previous works done before 2006,it found that the Wikipedia hyperlink network still followed power-law distribution on degree and the marco structure still obeyed bow-tie model,however,the proportion of different components defined in bow-tie model varied significantly.
