A Probabilistic Optimization Framework for the Empty-Answer Problem
Summary: Introduces a probabilistic optimization framework for the empty-answer problem to drive interactive query relaxation. It optimizes objectives to suggest relaxations with fewer predicates, offering optimal and approximate solvers and empirical gains over baselines. (summarized by gpt-5-nano on Feb 09 2026)
