SparqlFilterFlow: SPARQL Query Composition for Everyone

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 8798)

Abstract

SparqlFilterFlow provides a visual interface for the composition of SPARQL queries, in particular SELECT and ASK queries. It is based on the intuitive and empirically well-founded filter/flow model that has been extended to address the unique specifics of SPARQL and RDF. In contrast to related work, no structured text input is required but the queries can be created entirely with graphical elements. This allows even users without expertise in Semantic Web technologies to create complex SPARQL queries with only little training. SparqlFilterFlow is implemented in C#, supports a large number of SPARQL constructs and can be applied to any SPARQL endpoint.
