使用OWLAPI删除本体注释

Question

    OWLOntologyManager m = OWLManager.createOWLOntologyManager();
    OWLOntology ontology = null;
    File ontologyFile = new File(ontologyFileName);
    try {
        ontology = m.loadOntologyFromOntologyDocument(ontologyFile);
    } catch (OWLOntologyCreationException e) {
        e.printStackTrace();
    }
    for (OWLClass cls : ontology.getClassesInSignature()) {
        for (OWLAnnotation annotation : EntitySearcher.getAnnotations(cls.getIRI(), ontology)) {
            if (annotation.getValue() instanceof OWLLiteral) {
                RemoveOntologyAnnotation rm = new RemoveOntologyAnnotation(ontology, annotation);
                System.out.println(m.applyChange(rm));
            }
        }
    }

applyChange（）方法总是返回“unsuccessful”，我找不到任何关于注释删除不起作用的文档。

注：在http://sourceforge.net/p/owlapi/mailman/message/28203984/here似乎起作用

正如您的问题中链接的邮件列表线程中所指出的，关于本体的注释和关于本体元素的注释是两回事。

removeOntologyanNotation仅删除本体本身上的注释。

元素上的注释使用公理表示，特别是OWLANNotationAssertionAXIOM，因此，必须使用OWLontologyManager.RemoveAXIOM()或类似方法删除它们：

for (OWLClass cls : ontology.getClassesInSignature()) {
    for (OWLAnnotationAssertionAxiom annAx : EntitySearcher.getAnnotationAssertionAxioms(cls.getIRI(), ontology)) {
        if (annAx.getValue().getValue() instanceof OWLLiteral) {
            m.removeAxiom(annAx);
        }
    }
}
