Optimisation Techniques for Flexible SPARQL Queries [PDF]

open access: yesACM Transactions on the Web, 2022
Resource Description Framework datasets can be queried using the SPARQL language but are often irregularly structured and incomplete, which may make precise query formulation hard for users. The SPARQLARlanguage extends SPARQL 1.1 with two operators—APPROX and RELAX—to allow flexible querying over property paths.
