Aug 30, 2023 · I am looking for ontology based data access (OBDA) system capable of SPARQL to SQL query rewriting to convert the following SPARQL query.

A further SPARQL-to-SQL tool is Ultrawrap [11], which integrates closely with the database and utilizes views for answering SPARQL queries over relational data.

Query rewriting is done by adding positive and negative filters (corresponding respectively to permissions and prohibitions) to the initial query. Download to ...

We therefore propose a novel method, SPARQLprov, based on query rewriting, to compute how-provenance polynomials for SPARQL queries over knowledge graphs.

We therefore propose a novel method, SPARQLprov, based on query rewriting, to compute how-provenance polyno- mials for SPARQL queries over knowledge graphs.

In our query rewrit- ing solution, we combine the semantics and expressiveness of. SPARQL with notions of logic programming and adopt a rule- based formalism ...
