Relational Deep Dive: Error-Aware Queries Over Unstructured Data

Summary: ReDD dynamically discovers query-specific, joinable schemas and populates relational tables from unstructured corpora using LLMs plus hidden-state classifiers. SCAPE provides calibrated error detection with coverage guarantees, enabling accuracy–human-cost trade-offs and reducing extraction errors below 1%. (summarized by gpt-5.6-luna on Jul 09 2026)
