研究平台精选评论对讨论质量的影响，发现效果有限但能提升用户活跃度。
The Impact of Featuring Comments in Online Discussions
- 对比有无精选评论的新闻讨论，评估其影响
- 精选评论后用户参与度上升，但讨论质量未显著提升
- 适合关注平台运营策略与用户行为的研究者
在线新闻平台常通过精选高质量评论（如编辑推荐）进行内容管理。本文比较了设有精选评论与无精选评论的新闻讨论，从用户与平台视角评估讨论质量。结果表明，精选评论对讨论质量的提升作用有限；但首次精选后，讨论活跃度明显上升，说明该策略可能主要用于提高用户参与度，并延缓用户活跃度自然下降的趋势。
原文摘要 · Abstract (English)
A widespread moderation strategy by online news platforms is to feature what the platform deems high quality comments, usually called editor picks or featured comments. In this paper, we compare online discussions of news articles in which certain comments are featured, versus discussions in which no comments are featured. We measure the impact of featuring comments on the discussion, by estimating and comparing the quality of discussions from the perspective of the user base and the platform itself. Our analysis shows that the impact on discussion quality is limited. However, we do observe an increase in discussion activity after the first comments are featured by moderators, suggesting that the moderation strategy might be used to increase user engagement and to postpone the natural decline in user activity over time.
