RDFMutate: Mutation-Based Generation of Knowledge Graphs

Abstract

This paper introduces RDFMutate, the first mutation-based tool to generate RDF knowledge graphs. RDFMutate enables developers to analyze the robustness of applications that operate on RDF, by gen- erating variants of seed knowledge graphs, which are mutated according to a set of mutation operations and SHACL constraints. In contrast to existing tools to generate synthetic RDF graphs, RDFMutate provides a mutation-based approach that is accessible for both researchers and ap- plication developers, by providing a framework to define mutation rules and flexible selection of generated graphs.
