Web Record Extraction with Invariants

Summary: Introduce invariants for Web data records to relax prior assumptions of uniform schemas and linear layouts, enabling discovery of heterogeneous, nested records on modern pages. Propose Miria, a bottom-up recursive algorithm that reconstructs records from invariants and outperforms prior extractors. (summarized by gpt-5-mini on Feb 09 2026)
