- SPLENDID: SPARQL Endpoint Federation Exploiting VOID Descriptions + (AliBaba and DARQ fail to return results fo … AliBaba and DARQ fail to return results for six out of the 14 queries for different reasons. AliBaba generates malformed sub queries for CD3, CD5, LS6, and LS7. DARQ can not handle the unbound predicate in CD1 and LS2. For CD3 and CD5 DARQ opens too many connections to GeoNames. All other unsuccessful queries take longer than the time limit of five minutes. Overall, FedX has the best query evaluation performance. The reason is its novel and efficient query execution based on block transmission of result tuples and parallelization of joins. However, there is only a significant difference between FedX and SPLENDID for CD6, CD7, LS3, LS5-7. For the other queries SPLENDID is close to FedX and for CD3 and CD4 even slightly faster, which indicates that SPLENDID, indeed, generates better query execution plans.d, generates better query execution plans.)
