I am trying to use SPARQL to query data on Manchester United FC wikipedia page using dbpedia (which can be found here [http://dbpedia.org/page/Manchester_United_F.C.]).
I have successfully accessed dbo and dbp properties but I can't seem to access properties like "is dbp:winners of". Querying this property always results in an empty set. What am I doing wrong? Here's my query:
PREFIX db: <http://dbpedia.org/ontology/>
PREFIX dbpedia2: <http://dbpedia.org/property/>
SELECT ?club ?loc ?league ?trophy WHERE {
?club a db:SoccerClub.
?club dbpedia2:location ?loc.
?club db:league ?league.
?club dbpedia2:winners ?trophy
FILTER regex(str(?club), "Manchester")
}
