IQR: An Interactive Query Relaxation System for the Empty-Answer Problem
Summary: IQR is an interactive relaxation system for empty-answer queries, proposing one relaxation at a time under an optimization objective until a non-empty answer is found. Probabilistic user-acceptance guides relaxations toward diverse goals (effort, profit) with exact/approximate solvers, validated on large real datasets. (summarized by gpt-5-nano on Feb 09 2026)
