Querying Incomplete Numerical Data: Between Certain and Possible Answers
Summary: Model numerical nulls as marked nulls with probability distributions, yielding probabilistic bag DBs with repeated-null correlations and compositional semantics for arithmetic and aggregate queries. Show queries are measurable with finite outputs, and provide efficient approximations for output-interval probabilities (exact computation intractable). (summarized by gpt-5-mini on Feb 09 2026)
