Hello,
Very surprising results. The difference is so big that if you choose a random
resource from the large result set, then it will probably not exist in the
small result set. Have you tried?
By the way, how do the live endpoints (http://live.dbpedia.org/sparql,
http://dbpedia-live.openlinksw.com/sparql) compare to the standard endpoit
(http://dbpedia.org/sparql) in terms of:
- Amount of data
- Response time
- Availability
Anybody knows about that?
Regards,
Juan Lucas

Asunto: [Dbpedia-discussion] DBpedia Live End points return different datafor
same query
Hi,
I ran the following query against the two DBPedia live endpoints mentioned on
the DBpedia Live website (http://live.dbpedia.org/) and I get very different
results. Does anyone know why this could be happening? Do the graphs
"<http://dbpedia.org>" on these end points not contain the same data set?
Query:
PREFIX dbo: <http://dbpedia.org/ontology/>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX dbpprop: <http://dbpedia.org/property/>
SELECT count(*)
FROM <http://dbpedia.org>
WHERE
{ ?person rdf:type dbo:Person .
?person dbpprop:name ?name .
?person dbo:birthDate ?birthDate .
?person dbo:abstract ?abstract .
?person dbo:wikiPageID ?wikiPageID .
?person dbo:wikiPageRevisionID ?wikiPageRevisionID
OPTIONAL
{ ?person dbo:wikiPageModified ?wikiPageModified }
OPTIONAL
{ ?person dbo:wikiPageExtracted ?wikiPageExtracted }
FILTER langMatches(lang(?abstract), "en")
}
Result when run on end point http://live.dbpedia.org/sparql: 3792391
Result when run on end point http://dbpedia-live.openlinksw.com/sparql: 63450663
Thanks,
Shruti
