The 2021 RecSys conference takes place in Amsterdam September 27 — October 1. The deadline for submitting papers to the main track is already on May 4 (abstracts are due April 27), and that date is inching closer. With this blogpost, we like to draw your attention towards a few changes that have been made to the main paper track, compared to previous RecSys editions.

Based on what we’ve learned in recent years, RecSys’21 has implemented a numbers of changes compared to last year. All the details can be found on the official website…

Since its inception, RecSys has been a place to build a community. What started with 117 people meeting in Minnesota in 2007 has grown to over 750 converging next week on Vancouver, BC for its 12th edition.

Our driving principle in planning RecSys 2018 has been to maintain that sense of community even as the numbers grow.

The Recsys Amsterdam group, originally started in 2013 has now grown into a community of almost 500 people, who meet 3–4 times a year to discuss RecSys topics, with a focus on the startup and industry sphere.

Reaching hundred attendees in some of their events, the group has a clear purpose: “to increase…

In this post, we present a very opinionated list of 10 RecSys papers everyone should read. The first five papers are the top-5 most rated papers according to the ACM digital library (out of a list of 925 papers published). These five papers account for ~ 12% of all the RecSys conference papers citations!

Every year after RecSys, our community takes the time to reflect and write summaries and reviews of the conference. Wether you could not make it to the conference, or you missed a session, it is always a good idea to keep an eye on what others are thinking.
