基于倒易弧信息交换的维基百科增长模型
Model of Wikipedia growth based on information exchange via reciprocal arcs
摘要：
我们展示了互惠弧如何显着影响维基百科，在线百科全书的结构组织。结果表明，随机添加的倒易弧的静态网络不能解释所观察到的互惠维基百科。提出了一个基于偏好连接和信息交互的维基百科增长模型。我们的模型和真正的维基百科网络的度分布之间的一个很好的协议是实现没有拟合的分布，但仅仅通过提取少量的模型参数从真实网络的测量。
英文摘要：
We show how reciprocal arcs significantly influence the structural organization of Wikipedias, online encyclopedias. It is shown that random addition of reciprocal arcs in the static network cannot explain the observed reciprocity of Wikipedias. A model of Wikipedia growth based on preferential attachment and on information exchange via reciprocal arcs is presented. An excellent agreement between in-degree distributions of our model and real Wikipedia networks is achieved without fitting the distributions, but by merely extracting a small number of model parameters from the measurement of real networks.
