热门评论还是热门评论?预测和解释在线新闻讨论中的用户参与度

Top Comment or Flop Comment? Predicting and Explaining User Engagement in Online News Discussions

Julian Risch, Ralf Krestel

摘要:

在线新闻文章下面的评论部分在读者中越来越受欢迎。然而,大量的评论使得普通新闻消费者无法阅读所有评论,并阻碍了参与讨论。大多数平台按时间顺序显示评论,这忽略了其中一些评论与用户更相关,并且是更好的对话启动器。在本文中,我们系统地分析了用户参与度的形式,即评论收到的好评和回复。基于评论文本,我们训练了一个模型来区分那些有很高或很低机会获得许多赞同和回复的评论。我们对来自TheGuardian.com的用户评论的评估比较了递归和卷积神经网络模型以及传统的基于特征的分类器。此外,我们调查是什么让一些评论比其他评论更吸引人。为此,我们确定了参与触发因素,并将其按分类法进行排列。神经网络的解释方法揭示了哪些输入词对我们模型的预测影响最大。此外,我们评估了产品评论的数据集,这些评论表现出与用户评论相似的属性,例如对有用性的支持。

英文摘要:

Comment sections below online news articles enjoy growing popularity among readers. However, the overwhelming number of comments makes it infeasible for the average news consumer to read all of them and hinders engaging discussions. Most platforms display comments in chronological order, which neglects that some of them are more relevant to users and are better conversation starters. In this paper, we systematically analyze user engagement in the form of the upvotes and replies that a comment receives. Based on comment texts, we train a model to distinguish comments that have either a high or low chance of receiving many upvotes and replies. Our evaluation on user comments from TheGuardian.com compares recurrent and convolutional neural network models, and a traditional feature-based classifier. Further, we investigate what makes some comments more engaging than others. To this end, we identify engagement triggers and arrange them in a taxonomy. Explanation methods for neural networks reveal which input words have the strongest influence on our model's predictions. In addition, we evaluate on a dataset of product reviews, which exhibit similar properties as user comments, such as featuring upvotes for helpfulness.
