How to determine the subject and object of an object property assertion?
In OWLAPI, when you get the signature of an OWLAxiom of type AxiomType.OBJECT_PROPERTY_ASSERTION, how to know which of its entities is the subject and which is the object?
Don't try to do it from the signature. The signature is just a set, and doesn't have the information that you want. Instead, treat it as an OWLPropertyAssertionAxiom and use the getSubject() and getObject() methods.
