Temporal Reasoning in Recommendation
RecTemp 26: Workshop on Temporal Reasoning in Recommendation Systems
In conjunction with
ACM Conference on Recommender Systems 2026
September 28, 2026 - October 2, 2026
Minneapolis Marriott City Center
Minneapolis, Minnesota, United States
RecTemp is about time as a first-class signal rather than an index into a log. It covers sequential and session-based recommendation, seasonality and recurring intent, preferences that drift over a lifetime, item and catalogue lifecycles, and the temporal leakage that creeps into evaluation when a random split lets a model learn from the future. Useful for anyone whose offline numbers have failed to survive contact with production. Half-day workshop on the morning of Monday 28 September, the first workshop day.
