Querying Partially Sound and Complete Data Sources
Summary: Handles querying partially sound/incomplete source collections via a consistency check and a tableaux characterization of their possible worlds. Introduces a probabilistic semantics for answers to quantify confidence from the number and quality of contributing sources. (summarized by gpt-5-mini on Feb 09 2026)
