While anacademic conference, RecSys attracts many practitioners and industry researchers, with industry attendance making up the majority of attendees,[7] this is also reflected in the authorship of research papers.[8] Many works published at the conference have direct impact on recommendation and personalization practice in industry[9][10][11] affecting millions of users.
Recommender systems are pervasive in online systems, the conference provides opportunities for researchers and practitioners to address specific problems in various workshops in conjunction with the conference, topics include responsible recommendation,[12] causal reasoning,[13] and others. The workshop themes follow recent developments in the broader machine learning and human-computer interaction topics.
The conference is the host of the ACMRecSys Challenge, a yearly competition in the spirit of theNetflix Prize focussing on a specific recommendation problem. The Challenge has been organized by companies such asTwitter,[14] andSpotify.[15] Participation in the challenge is open to everyone and participation in it has become a means of showcasing ones skills in recommendations,[16][17] similar toKaggle competitions.
TheNetflix Prize was a recommendation challenge organized byNetflix between 2006 and 2009. Shortly prior to ACM RecSys 2009, the winners of the Netflix Prize were announced.[18][19] At the 2009 conference, members of the winning team (Bellkor's Pragmatich Chaos) as well as representatives from Netflix convened in a panel on the lessons learnt from the Netflix Prize[20]
In 2022, at one of the workshops at the conference, a paper fromByteDance,[21] the company behindTikTok, described in detail how a recommendation algorithm for video worked. While the paper did not point out the algorithm as the one that generates TikTok's recommendations, the paper received significant attention in technology-focused media.[22][23][24][25]
The ACM Recommender Systems Conference (RecSys) has experienced significant growth since its first event in 2007.[2][26] The number of paper submissions has steadily increased over the years. From an initial 35 submissions in 2007, the conference has seen over 250 submissions annually in recent years. While the number of submissions has increased, the conference's acceptance rate has become more selective, declining from 46% in its inaugural year to a range of 17-24% in more recent editions.
