维基百科收录的文章和参与编辑的用户日益增多,其中不乏一些用户对同一条目持有不同的见解。该文旨在发现维基百科中的争议性文章,通过维基百科提供的历史信息,在传统的挖掘方法基础上,对具有特殊属性的用户角色进行总结并融合到排序模型中,探讨这类用户对争议性文章挖掘的作用。在 16-745篇文章组成的数据集上进行了实验,除传统的PRF和NDCG评价外,该文给出了更直观的排序结果,与其他基准模型相比有较大的提升。
Abstract
The number of Wikipedia articles and contributors grows at a very fast pace, therefore, a remarkable property of some Wikipedia articles were written by up to thousands of authors who have contradicting opinions. This paper aims to indentify controversial articles in Wikipedia. It draws clues from the edit history page in Wikipedia based on the traditional methods, and takes into account the contributors of the corresponding article to compute controversial scores. We also introduce a new intuitive evaluation method besides the PRF and NDCG evaluation metrics. Experiments on 16745 Wikipedia articles show that our methods perform much better than the other baseline models.
