從java中的owl獲取所有classess，sub classess

Question

我有本體文件。 貓頭鷹，我需要從貓頭鷹獲得所有類，子類

File file = new File("myontology.owl");

OWLOntology myontology = manager.loadOntologyFromOntologyDocument(file);
System.out.println("Loaded ontology: " + myontology);

// We can always obtain the location where an ontology was loaded from
IRI documentIRI = manager.getOntologyDocumentIRI(myontology);

OWLDataFactory factory = manager.getOWLDataFactory();
OWLClass clsOwl = factory.getOWLClass(documentIRI);

那我該怎么寫？ 我檢查了OWLAPI，但我對語義非常新。 為了得到 ，

像下面的例子，使用owl2api我需要一個代碼，

String uri = "http://protege.cim3.net/file/pub/ontologies/travel/travel.owl";

OWLModel owlModel = ProtegeOWL.createJenaOWLModelFromURI(uri);

Collection classes = owlModel.getUserDefinedOWLNamedClasses();
for (Iterator it = classes.iterator(); it.hasNext();) {

    OWLNamedClass cls = (OWLNamedClass) it.next();
    Collection instances = cls.getInstances(false);
    System.out.println("Class " + cls.getBrowserText() + " (" + instances.size() + ")");

    for (Iterator jt = instances.iterator(); jt.hasNext();) {
        OWLIndividual individual = (OWLIndividual) jt.next();
        System.out.println(" - " + individual.getBrowserText());
    }
}

謝謝

不確定這是否是你需要的，但是

OwlOntology.getClassesInSignature() 

返回用於在當前本體中構建公理的所有類的集合。

一旦你擁有了OwlClass，你就可以使用它來獲得它的子類

 OwlClass.getSubClasses(OWLOntology)
