Hello,


Result to my dbpedia query :
SELECT ?president ?party WHERE {
?president <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://dbpedia.org/ontology/President> . ?president <http://dbpedia.org/ontology/nationality> <http://dbpedia.org/resource/United_States> .
?president <http://dbpedia.org/ontology/party> ?party . }

doesn't contain <http://dbpedia.org/resource/Dwight_D._Eisenhower <http://dbpedia.org/page/Dwight_D._Eisenhower>> resource. Because this resource has not anymore <http://dbpedia.org/resource/United_States <http://dbpedia.org/page/United_States>> property. This query is part of FedBench query <http://iwb.fluidops.com:7879/resource/fbench:q/cross-domain_3> for evaluation. Could you add this property again to this resource plesase ?

If you check the infobox of president "Dwight D. Eisenhower" on Wikipedia, it does not contain property nationality. So it's not right to add it manually to DBpedia. But you can still get the required information from DBpedia via the following query:

   SELECT ?president ?party WHERE {
   ?president <http://www.w3.org/1999/02/22-rdf-syntax-ns#type>
   <http://dbpedia.org/class/yago/PresidentsOfTheUnitedStates> .
   ?president <http://dbpedia.org/ontology/party> ?party . }
