Hi,
I've got an OntModel with OnModelSpec.OWL_MEM_RULE_INF set that
contains about 25.000 statements and only 1(!) transitive property.
Now I'm trying to list all Statements with a special subject
(http://myResource) by calling
StmtIterator iter =
model.listStatements(model.createResource("http://myResource";), null,
(RDFNode) null);
Although execution of this method does not take a long time (some
seconds) I run in serious trouble/performance issue when calling
iter.hasNext();
This call does not terminate within 5 minutes and I'm asking myself if
what's wrong. Therefore I'm looking for better solution and your
suggestions... ;-)
Best,
Thorben
Some problem with:
String query = "SELECT ?s ?p ?o WHERE {?s ?p ?o. FILTER(?s
=<METEX://knowledge/infection> ).}";
QueryExecution qexec= QueryExecutionFactory.create(query,
tmpModel);
ResultSet rs = qexec.execSelect();
Is there a way or need to explicitly define a customized index?
Thorben
