Controversial Ideas & Discussions

In our blog, we once in a while publish controversial ideas of which we believe that a discussion may advance the recommender-system community.

These blog posts a as follows.

When will the ACM RecSys Conference have a rebuttal phase (again)?

Update 2024-02-26: I just learned that the ACM RecSys Conference 2024 will also have a rebuttal period. Awesome! NeurIPS has it, the AutoML Conference has it, CHI has it (kind of), and many other conferences as well — a ‘rebuttal’ or ‘author’s response’ phase.

Recently, i.e. for 2 years or so, I had the feeling that submissions relating to recommender systems strongly increased at SIGIR, especially this year. My impression seems to be confirmed today: According […]

Why is there no ‘International Journal on Recommender Systems’?

It seems that only the recommender-system community has no journal, exclusively for its community. Top recommender-system articles beyond the ~8-page limit for the ACM RecSys Conference hence are scattered across many different […]

‘Papers with Code’ / NeurIPS Guidelines for Publishing Research Code: A Role Model For Recommender-Systems?

The recommender-system community is facing a reproducibility crisis. This has recently been demonstrated by the authors of the paper Are we really making much progress? A worrying analysis of recent neural recommendation approaches (Maurizio Ferrari Dacrema, Paolo Cremonesi, Dietmar Jannach).

Why are there no continental chapters of the ACM Conference on Recommender Systems? E.g. the Asian or European Conference on Recommender Systems (RecSysAsia / RecSysEU)?

The number of submissions and participants at the ACM Conference on Recommender Systems is increasing, year by year. Sometimes, the conference is even sold out or moves short-notice to a new larger venue. Acceptance rates decreased from 46% in its first year (2007) to below 20% in recent years. Among the rejected papers, there are […]
