Quality Assessment of Wikipedia Articles Using h-index

Abstract

In this paper, we propose a method for assessing quality values of Wikipedia articles from edit history using h-index. One of the major methods for assessing Wikipedia article quality is a peer-review based method. In this method, we assume that if an editor's texts are left by the other editors, the texts are approved by the editors, then the editor is decided as a good editor. However, if an editor edits multiple articles, and the editor is approved at a small number of articles, the quality value of the editor deeply depends on the quality of the texts. In this paper, we apply h-index, which is a simple but resistant to excessive values, to the peer-review based Wikipedia article assessment method. Although h-index can identify whether an editor is a good quality editor or not, h-index cannot identify whether the editor is a vandal or an inactive editor. To solve this problem, we propose p-ratio for identifying which editors are vandals or inactive editors. From our experiments, we confirmed that by integrating h-index with p-ratio, the accuracy of article quality assessment in our method outperforms the existing peer-review based method.
