第17届推荐系统年会（ACM RecSys）将在2023年9月18日到22日于新加坡举办。值得注意的是，本届年会是疫情发生以来的首次线下参会，大家可以在线下共享推荐系统领域的最新研究进展（面基）。并且这也是RecSys入选CCF推荐列表B类会议的首次会议，相信未来会有更多研究者瞄准这一会议进行投稿。

- RecSys2021推荐系统论文集锦
- RecSys2020推荐系统论文集锦
本年度的长文会议论文接收列表已于2023年6月26日在官方网站公布，包括47篇长文论文（去年长文录用为38篇）。截至目前，短文会议论文的结果目前还未公布，大家可以再期待一下。推荐系统年会相比于其他机器学习、数据挖掘顶会来说侧重于探讨推荐系统领域更加实际的研究话题以及更加新颖的研究角度，因此我们可以期待今年的会议都会收录哪些有意思或者有想法的论文。
