Useful SPARQL queries

This page collects SPARQL queries for the DBpedia Live Extraction. Most of them give examples of how to query specific T-Box parts with the help of annotations. The queries can be executed here: http://dbpedia-live.openlinksw.com/sparql default-graph: http://dbpedia.org/meta

Retrieve the DBpedia Ontology

PREFIX meta: <http://dbpedia.org/meta/>
CONSTRUCT {?s ?p ?o} WHERE
{
?b meta:origin meta:TBoxExtractor .
?b owl:annotatedSource ?s .
?b owl:annotatedProperty ?p .
?b owl:annotatedTarget ?o .
FILTER(!(?p IN (
   meta:editlink, 
   meta:editLink, 
   meta:revisionlink,
   meta:revisionLink,
   meta:oaiidentifier,
   meta:oaiidentifier,
   <http://http://purl.org/dc/terms/modified>
))).

Retrieve the DBpedia Ontology without disjointWith and equivalentClass Axioms

Note: these axioms have the potential to render the ontology inconsistent

PREFIX meta: <http://dbpedia.org/meta/>
PREFIX owl: <http://www.w3.org/2002/07/owl#>

CONSTRUCT {?s ?p ?o} WHERE
{
?b meta:origin meta:TBoxExtractor .
?b meta:aspect ?aspect .
?b owl:annotatedSource ?s .
?b owl:annotatedProperty ?p .
?b owl:annotatedTarget ?o .
FILTER(!(?p IN (
   meta:editlink, 
   meta:editLink, 
   meta:revisionlink,
   meta:revisionLink,
   meta:oaiidentifier,
   meta:oaiidentifier,
   <http://http://purl.org/dc/terms/modified>
))).
FILTER (!(?aspect IN(
   owl:equivalentClass,
   owl:disjointWith
))).
