Document Spanners — A Brief Overview of Concepts, Results, and Recent Developments
Summary: Survey of the document spanners framework (formalising AQL/SystemT) and its theoretical foundations—expressiveness (regex formulas, core spanners), complexity, and algebraic properties. Highlights recent advances in enumeration, containment, extensions, and connections to automata and logic. (summarized by gpt-5-mini on Feb 09 2026)
