Static Analysis and Optimization of Semantic Web Queries
Summary: Introduces pattern trees as tree-shaped execution plans for well-designed SPARQL, enabling transformation rules and a simple normal form that capture OPTIONAL-specific semantics. Studies equivalence/containment and the enumeration/counting complexity for this fragment. (summarized by gpt-5-mini on Feb 09 2026)
