[英]Access ontology through OWL API
我想使用Eclipse通过OWL API访问我的本体和SWRL规则。 任何人都可以提供可以告诉我该怎么做的确切程序的帮助吗?
我已经尝试了以下代码,但似乎没有任何反应。 请记住,我的Java技能很差。
我将需要一个确切的程序来解决该问题。
我已经拥有的代码是:
public static void main(String[] args) {
File file = new File("file:c:/Users/DTN/Desktop/Final SubmissionFilteringMechanism_Ontology.owl");
OWLOntologyManager m = OWLManager.createOWLOntologyManager();
OWLDataFactory f = OWLManager.getOWLDataFactory();
OWLOntology o = null;
public void testAddAxioms() {
try {
o = m.loadOntologyFromOntologyDocument(Ont_Base_IRI);
OWLClass clsA = f.getOWLClass(IRI.create(Ont_Base_IRI + "ClassA"));
OWLClass clsB = f.getOWLClass(IRI.create(Ont_Base_IRI + "ClassB"));
OWLAxiom ax1 = f.getOWLSubClassOfAxiom(clsA, clsB);
AddAxiom addAxiom1 = new AddAxiom(o, ax1);
m.applyChange(addAxiom1);
for (OWLClass cls : o.getClassesInSignature()) {
EditText edit = (EditText) findViewById(R.id.editText1);
edit.setText((CharSequence) cls);
}
m.removeOntology(o);
} catch (Exception e) {
EditText edit = (EditText) findViewById(R.id.editText1);
edit.setText("Not successfull");
}
}
}
装载和修改本体OWLAPI的例子是在这里你会发现两者的一般性介绍和一组具体的例子。 如果您需要某些特定代码的帮助,可以将其发布到OWLAPI邮件列表。
