推荐系统是缓解信息过载的重要工具，在人们的日常生活中扮演着重要的角色。由于建议涉及社会资源的分配（例如，工作推荐），一个重要的问题是推荐是否公平。不公正的推荐不仅不道德，而且损害了推荐人制度本身的长远利益。因此，推荐系统中的公平性问题最近引起了越来越多的关注。然而，由于多个复杂的资源分配过程和各种公平性的定义，在推荐公平性的研究是分散的。为了填补这一空白，我们回顾了在顶级会议/期刊上发表的60多篇论文，包括TOIS，SIGIR和WWW。首先，我们总结了建议中的公平性定义，并提供了几种观点来分类公平性问题。然后，我们回顾了公平性研究中的推荐数据集和测量，并提供了一个详细的分类公平性方法的建议。最后，我们通过概述一些有希望的未来方向来结束这项调查。
Recommender systems are an essential tool to relieve the information overload challenge and play an important role in people's daily lives. Since recommendations involve allocations of social resources (e.g., job recommendation), an important issue is whether recommendations are fair. Unfair recommendations are not only unethical but also harm the long-term interests of the recommender system itself. As a result, fairness issues in recommender systems have recently attracted increasing attention. However, due to multiple complex resource allocation processes and various fairness definitions, the research on fairness in recommendation is scattered. To fill this gap, we review over 60 papers published in top conferences/journals, including TOIS, SIGIR, and WWW. First, we summarize fairness definitions in the recommendation and provide several views to classify fairness issues. Then, we review recommendation datasets and measurements in fairness studies and provide an elaborate taxonomy of fairness methods in the recommendation. Finally, we conclude this survey by outlining some promising future directions.
