摘要:

用户越来越依赖社交媒体订阅来消费日常信息。提要中的项目,如新闻、问题、歌曲等,通常是由用户的社交联系人、她的兴趣和她在平台上的行为的复杂相互作用引起的。用户自己的行为和接收到的提要之间的关系通常令人困惑,许多用户希望清楚地解释为什么向他们显示某些项目。透明度和可解释性是现代世界中认知过载、过滤气泡、用户跟踪和隐私风险的关键问题。本文介绍了FAIRY,一个框架,系统地发现,排名,并解释用户的行动和项目之间的关系,在他们的社交媒体提要。我们在平台上的用户的本地邻居建模为交互图,异构信息网络的一种形式,仅从有关用户容易访问的信息构建。我们假设该交互图中连接用户和她的提要项的路径可以作为用户的相关解释。这些路径是用一个学习排名模型来评分的,该模型捕捉了相关性和可重复性。两个社交平台上的用户研究证明了FAIRY方法的实际可行性和用户利益。

英文摘要:

Users increasingly rely on social media feeds for consuming daily information. The items in a feed, such as news, questions, songs, etc., usually result from the complex interplay of a user's social contacts, her interests and her actions on the platform. The relationship of the user's own behavior and the received feed is often puzzling, and many users would like to have a clear explanation on why certain items were shown to them. Transparency and explainability are key concerns in the modern world of cognitive overload, filter bubbles, user tracking, and privacy risks. This paper presents FAIRY, a framework that systematically discovers, ranks, and explains relationships between users' actions and items in their social media feeds. We model the user's local neighborhood on the platform as an interaction graph, a form of heterogeneous information network constructed solely from information that is easily accessible to the concerned user. We posit that paths in this interaction graph connecting the user and her feed items can act as pertinent explanations for the user. These paths are scored with a learning-to-rank model that captures relevance and surprisal. User studies on two social platforms demonstrate the practical viability and user benefits of the FAIRY method.
