Before revision:  We present an empirical evaluation for the validity of our approach by formalizing the graph pattern matching construct of Gremlin and illustrate its mapping to corresponding SPARQL queries. Moreover, we also present a proof-of-concept implementation of our approach, demonstrate its validity and applicability by executing SPARQL queries on top of leading Graph stores ( Neo4J, Sparksee, and Apache TinkerGraph ) and compare their performances with RDF stores (Openlink Virtuoso, 4Store , and JenaTDB).
After revision:  We present a comprehensive empirical evaluation of Gremlinator and demonstrate its validity and applicability by executing SPARQL queries on top of leading Graph stores ( Neo4J, Sparksee, and Apache TinkerGraph ) and compare their performances with RDF stores (Openlink Virtuoso, 4Store , and JenaTDB).
