Semantic Representations and Query Languages for Or-sets
Summary: Presents a query language for or-sets, distinguishing ‘‘structural’’ vs ‘‘conceptual’’ queries via a normalization framework and proving lossless normalization for a broad class of queries. Gives upper bounds on normalization cost and a Rounds-style semantics. (summarized by gpt-5-mini on Feb 09 2026)
