Static Analysis of Semantic Web Queries with ShEx Schema Constraints. (Analyse Statique de Requêtes du Web Sémantique avec Contraintes de Schéma ShEx).

, 2017
Data structured in the Resource Description Framework (RDF) are increasingly available in large volumes. This leads to a major need and research interest in novel methods for query analysis and compilation for making the most of RDF data extraction. SPARQL is the widely used and well supported standard query language for RDF data.
