Question

Answer 1

You create an OWLObjectProperty using the aptly named OWLDataFactory.getOWLObjectProperty(IRI iri) , and IRI has a constructor IRI(String) . Eg, from the examples in the documentation:

OWLObjectProperty prop
  = factory.getOWLObjectProperty(IRI.create(ontologyIRI + "#propA"));

Answer 2

如果您使用的是OWLAPI，则可以重复使用此处的代码来解析DL查询： https ： //github.com/owlcs/owlapi/wiki/DL-Queries-with-a-real-reasoner
