A Probabilistic Framework for Vague Queries and Imprecise Information in Databases

Summary: Probabilistic model for vague queries and missing/imprecise data; yields a ranked object list, not a fixed answer. Vague predicates and relevance feedback refine rankings; probabilistic formulas extend predicates to handle missing/imprecise values. (summarized by gpt-5-nano on Feb 09 2026)
