Processing SPARQL queries over large federations of endpoints is crucial for keeping the Semantic Web decentralized.Despite existence hundreds endpoints, current federation engines only scale to dozens.One major issue comes from definition source selection problem, i.e., finding minimal set contact per triple pattern.Even if such a minimal, few combinations sources may return results.Consequently, most query processing time wasted evaluating that no results.In this paper, we introduce...
Processing SPARQL queries over large federations of endpoints is essential for maintaining the Semantic Web decentralized. However, existing federation engines struggle to query more than a dozen endpoints. We recently proposed FedUP, new type engine based on unions-over-joins plans that outperforms state-of-the-art by orders magnitude federations. This demonstration paper introduces Fediscount, federated online shopping application FedShop benchmark, illustrating capabilities FedUP. The...
