ACM RecSys 2027 — 21st ACM Conference on Recommender Systems

ACM RecSys 2027, the 21st ACM Conference on Recommender Systems, runs 23-27 August 2027 at the Hilton Hawaiian Village Waikiki Beach Resort in Honolulu, O'ahu, Hawai'i, under general co-chairs Christine Bauer, Joeran Beel and Bamshad Mobasher. RecSys is the international conference dedicated to recommender systems — the machine-learning models behind feeds, ranking, product discovery and personalisation — and it runs tutorials and workshops alongside the main conference programme. The chairs announced the location in September 2025, choosing Hawai'i for its workable time-zone overlap between the Americas and Asia-Pacific and noting the islands have previously hosted UMAP 2010, CIKM 2012 and SIGCHI 2024. Programme tracks and the call for papers have not yet been released; the venue, the dates and the chairs are confirmed on the official site.

Recommendation is the highest-leverage machine learning most consumer and commerce businesses run, and RecSys is the one venue where the people operating it at scale publish and argue about the things that actually bite: evaluation, cold start, feedback loops, and the gap between offline metrics and live outcomes. A head of personalisation, a data science director or a CTO at a marketplace, retailer or streaming service gets five days of peer-reviewed work plus tutorials and workshops — and a full year of lead time to plan, since the venue and dates are already fixed and the 2026 edition priced main-conference access at $800 for members.

• ✓Main conference programme, 23-27 August 2027
• ✓Tutorials and workshops, sold as a separate registration tier at RecSys 2026
• ✓Single-venue conference hotel — the Hilton Hawaiian Village Waikiki Beach Resort
• ✓General co-chairs Christine Bauer, Joeran Beel and Bamshad Mobasher
• ✓Scheduled for time-zone overlap between the Americas and Asia-Pacific
• ✓Programme tracks and calls for contributions to be announced through the official RecSys channels

• ★The only international conference given over entirely to recommender systems, rather than treating recommendation as one track inside a broader ML or IR venue.
• ★Venue and dates are locked a full year ahead — Hilton Hawaiian Village Waikiki Beach Resort, 23-27 August 2027 — which is unusual for an ACM conference and makes travel and budget approval straightforward.
• ★The location was chosen deliberately for workable time-zone overlap between the Americas and Asia-Pacific, per the chairs' own announcement.
• ★Three general co-chairs spanning European and US institutions: Christine Bauer, Joeran Beel and Bamshad Mobasher.
• ★Single conference-hotel format, so sessions, tutorials and the hallway track all sit in one property.
