On the Provenance of Non-Answers to Queries over Extracted Data

Summary: Non-answer provenance for queries over extracted data; explains why a tuple is not in the result. Proposes a mechanism to generate and present non-answer provenance, enabling researchers to assess extraction uncertainty and explain missing results. (summarized by gpt-5-nano on Feb 09 2026)
