NLProveNAns: Natural Language Provenance for Non-Answers
Summary: NLProveNAns, a natural-language DB interface, explains non-answers to non-expert users. It highlights NL-query fragments responsible for missing results and supports two why-not provenance flavors: frontier-picky (brief) and why-not polynomial (detailed).
