SPARQL Query Result Explanation for Linked Data


In this paper, we present an approach to explain SPARQL query results for Linked Data using why-provenance. We present a non-annotation-based algorithm to generate why-provenance and show its feasibility for Linked Data. We present an explanation-aware federated query processor prototype and show the presentation of our explanations. We present a user study to evaluate the impacts of our explanations. Our study shows that our query result explanations are helpful for end users to understand the result derivations and make trust judgments on the results.
