Dbpedia alternative names

I have been trying to get the names of singers along with their alternative names from dbpedia. Any idea what I am doing wrong? When I include alias I get no results

PREFIX dbo: <http://dbpedia.org/ontology/>
PREFIX dbr: <http://dbpedia.org/resource/>
PREFIX dbr: <http://dbpedia.org/property/>

SELECT ?singer ?alternativeName
WHERE { 
 ?x dbo:musicalArtist ?singer.
 ?x dbp:alias ?alternativeName.
}
Solution

  • There are no aliases. To verify run with OPTIONAL, i.e.

    PREFIX dbo: <http://dbpedia.org/ontology/>
PREFIX dbr: <http://dbpedia.org/resource/>
PREFIX dbp: <http://dbpedia.org/property/>

SELECT ?singer ?alternativeName
WHERE { 
   ?x dbo:musicalArtist ?singer.
   OPTIONAL{?x dbp:alias ?alternativeName.}
}
