Hi,
I have been trying to run the following sparql query on
http://dbpedia.org/sparql but failed to get any result. Could someone tell
me why?
PREFIX dbo: <http://dbpedia.org/ontology/>
SELECT DISTINCT ?x, ?z, ?y WHERE {
?z a dbo:Organisation .
?y a dbo:RadioStation .
?0 rdfs:label ?label0 .
?label0 bif:contains '"Louisiana"' .
?x dbo:state ?0 .
?y dbo:city ?x .
?y dbo:owner ?z .
}
Instead, if I don't use the bif:contains function, the query works, as shown
below
PREFIX dbo: <http://dbpedia.org/ontology/>
PREFIX db: <http://dbpedia.org/resource/>
SELECT DISTINCT ?x, ?z, ?y WHERE {
?z a dbo:Organisation .
?y a dbo:RadioStation .
?x dbo:state db:Louisiana .
?y dbo:city ?x .
?y dbo:owner ?z .
}
However, it seems the bif:contains works for some other queries.
Many thanks,
Lushan Han
