InternalReasonerException ( "Adding a subproperty chain that has a single element!" )

[Guilherme Melo e Maranhão]

Hello guys,

These are the lines to prepare my ontology to be infered by Pellet reasoner.

OWLReasonerFactory reasonerFactory = com.clarkparsia.pellet.owlapiv3.PelletReasonerFactory.getInstance();
OWLReasoner reasoner = reasonerFactory.createReasoner(ontology);

After the second one, an InternalReasonerExcpetion is thrown: "Adding a subproperty chain that has a single element!"

What exactly does it mean? I didn't find anything wrong with my ontology.

Thanks,

Guilherme

Hello, 

you probably have some statement like

SubObjectPropertyOf(ObjectPropertyChain(:property1) :property2)

in your model. If you are using protege as an editor, you could look for entries in "Superproperty Of (Chain)" in the Object Properties tab.

Greetings

Hello,

I have the same error in my programm. You are right. I'm using the editor Protege und have inserted valus into the option "Superproperty Of (Chain)". But the problem is, how did you fix this error in your codes?

Thank

Vincent
