基于双模社会网络的Wikipedia作者信任模型

Trust Model for Wikipedia Editors Based on Two-mode Social Network

[目的/意义]评价Wikipedia中作者的可信度。[方法/过程]将Wikipedia中作者与词条的编辑关系表示成一个带权值的有向双模网络图,通过对该网络图的全面分析,构建一个新的作者信任评价算法。该算法将作者信任值按类划分,并综合每个类下作者的相对编辑量、编辑错误因子和词条网络簇合系数等因素。[结果/结论]仿真实验表明,该算法能够很好地区分作者在不同类下的信任情况并识别具体类别中的高信任作者和低信任作者。

[ Purpose/significance ] This paper aims to evaluate the credibility of Wikipedia editors. [ Method/ process] This paper expresses the relationship between the Wikipedia editor and entry as a two-mode social network with weight, and builds a new trust evaluation algorithm for editors through the comprehensive analysis onfthis network. The algorithm calculates and divides author＇ s trust values, colligating their relative amount of editing, editing error factor and clusters coefficient of the entry network under each class. [ Result/conclusion] It shows that the algorithm is able to distinguish editor trust degree under different classes and identify high trust editors or low trust editors in one classes.
