Document Spanners for Extracting Incomplete Information: Expressiveness and Complexity
Summary: Extends document spanners with mappings to extract incomplete or optional information, simplifying regex-formula and rule semantics. Compares their expressive power and analyzes enumeration, satisfiability, and containment complexity. (summarized by gpt-5.6-luna on Jul 26 2026)
