Visual Diagrammatic Queries in ViziQuer: Overview and Implementation

no code implementations27 Apr 2023 Jūlija Ovčiņņikiva, Agris Šostaks, Kārlis Čerāns

In this paper we review the visual ViziQuer notation from the end-user point of view and describe the conceptual and technical solutions (including abstract syntax model, followed by a generation model for textual queries) that allow mapping of the visual diagrammatic query notation into the textual SPARQL language, thus enabling the execution of rich visual queries over the actual knowledge graphs.
