比赛名称：Recommender Systems Challenge

CAMRa track
CAMRa track at RecSysChallenge focuses on context-aware recommendation of movie-related news from moviepilot.com.
ScienceRec track
ScienceRec track focuses on recommendations to users about scientific papers that they might be interested in, using a data set that comes from the Mendeley system.

RecSys 2014 Challenge

http://2014.recsyschallenge.com/

比赛名称：User Engagement as Evaluation

比赛任务：In this challenge, we intend to use a different means of evaluating recommendations. Instead on focusing on predictive qualities, our intention is to optimize recommendations on user engagement.

RecSys 2016 Challenge

http://2016.recsyschallenge.com/

比赛任务：given a XING user, the goal is to predict those job postings that a user will positively interact with (e.g. click, bookmark).

RecSys 2017 Challenge

https://www.recsyschallenge.com/2017/

比赛任务：The ACM RecSys Challenge 2017 is focussing on the problem of job recommendations on XING in a cold-start scenario.

RecSys 2018 Challenge

比赛任务：This year’s challenge focuses on music recommendation, specifically the challenge of automatic playlist continuation.

RecSys 2019 Challenge

https://www.recsyschallenge.com/2019/

比赛任务：This year’s challenge focuses on travel metasearch. The goal of this challenge is to develop a session-based and context-aware recommender system using various input data to provide a list of accommodations that will match the needs of the user.

RecSys 2020 Challenge

https://www.recsyschallenge.com/2020/

比赛任务：The challenge focuses on a real-world task of tweet engagement prediction in a dynamic environment. The goal is to predict the probability for different types of engagement.

RecSys 2021 Challenge

https://www.recsyschallenge.com/2021/

比赛任务：This year’s challenge brings the problem even closer to Twitter’s real recommender systems by introducing latency constraints. We will also increase the data size to encourage novel methods.
