Solve queries about owlapi HOT 6 CLOSED

The ability of the parser to understand "property some entity" depends on the ontology declaring the property and the class and its short form provider being able to map "property" and "entity" to their full IRI.

Without the ontology and the code, I cannot be more precise in what might be the reason behind your issue.
As an example you can check https://github.com/owlcs/owlapi/tree/master/contract/src/test/java/org/coode/owlapi/examples

from owlapi.

i tried to make similar queries to the koala but still not working.
how can i send you the ontology ?

from owlapi.

If the ontology is small you can paste it here.
I have the koala ontology so you don't need to send me that. Can you paste the code you're using instead?

The problem in your code is at line 146:

OWLReasonerFactory reasonerFactory = new StructuralReasonerFactory();

You need to replace the structural reasoner with a real reasoner.
I have pasted an example with HermiT at this URL:
