In this paper, the authors present an approach for scalable processing of SPARQL queries to RDF (Resource Description Framework) views of numerical data stored in Relational DataBases (RDBs). Such queries include numerical expressions, inequalities, comparisons, etc. inside filters. They call such FILTERs numerical expressions and the queries - numerical SPARQL queries. For scalable execution of numerical SPARQL queries over RDBs, numerical operators should be pushed into SQL rather than executing the filters as post-processing outside the RDB; otherwise the query execution is slowed down, since a lot of data is transported from the RDB server and furthermore indexes on the server are not utilized.
