Since the Virtuoso version is updated recently, when I try to use the query below on the public DBpedai SPARQL endpoint. The result is empty.
PREFIX rdf:<http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX dbo:<http://dbpedia.org/ontology/>
PREFIX vrank:<http://purl.org/voc/vrank#>
SELECT ?s ?v
FROM <http://dbpedia.org>
FROM <http://people.aifb.kit.edu/ath/#DBpedia_PageRank>
WHERE {
?s rdf:type dbo:University.
?s vrank:hasRank/vrank:rankValue ?v.
}
ORDER BY DESC(?v) LIMIT 50
Thank you!
