Querying Websites Using Compact Skeletons

Summary: Proposes compact skeletons, a formal website-structure inference that maps hierarchical web/XML to relational tables and enables automated wrapper generation. Defines classes with polynomial-time construction algorithms, practical heuristics, and empirical validation. (summarized by gpt-5-mini on Feb 09 2026)
