In this work, we present UPSP, a new source selection approach for SPARQL query federation over multiple SPARQL endpoints. ...
Efficient source selection is one of the most important optimization steps in federated SPARQL query processing as it leads to more efficient query execution plan generation. ...
Introduction Federated SPARQL query engines mostly perform triple pattern-wise source selection (TPWSS) for SPARQL query federation over multiple SPARQL endpoints (data sources or only sources for short ...

Results: We compare TopFed with a well established federation engine FedX in terms of source selection and query execution time by using 10 different federated SPARQL queries with varying requirements. ...
Having the TCGA data distributed across multiple SPARQL endpoints, we enable biomedical scientists to query and retrieve information from these SPARQL endpoints by proposing a TCGA tailored federated SPARQL ...
Further, we are thankful to Alex Parker from Foundation Medicine for providing valuable feedback on the results of biological SPARQL query show in Figure 1 . ...
