Как создать подклассы в OWL с использованием OWL 2

Question

Как создать подклассы с использованием owl api? С помощью протеже было создано следующее.

<owl:Class rdf:about="http://www.semanticweb.org/muz_a/ontologies/2016/diseasesymptomogy-9#dizziness"> 
     <rdfs:subClassOf rdf:resource="http://www.semanticweb.org/muz_a/ontologies/2016/diseasesymptomogy-9#symptom"/> 
     <rdfs:label>dizziness</rdfs:label> 
</owl:Class>` 
<owl:Class rdf:about="http://www.semanticweb.org/muz_a/ontologies/2016/diseasesymptomogy-9#dizziness"> 
     <rdfs:subClassOf rdf:resource="http://www.semanticweb.org/muz_a/ontologies/2016/diseasesymptomogy-9#symptom"/> 
     <rdfs:label>dizziness</rdfs:label> 
</owl:Class> 

Answer 1

документация доступны here есть примеры того, как добавлять, удалять и сохранять изменения в онтологию.

https://github.com/owlcs/owlapi/blob/version4/contract/src/test/java/org/semanticweb/owlapi/examples/Examples.java

@Test 
public void shouldAddAxiom() throws Exception { 
    OWLOntologyManager manager = OWLManager.createOWLOntologyManager(); 
    IRI ontologyIRI = IRI.create("http://www.co-ode.org/ontologies/testont.owl"); 
    IRI documentIRI = IRI.create("file:/tmp/MyOnt.owl"); 
    SimpleIRIMapper mapper = new SimpleIRIMapper(ontologyIRI, documentIRI); 
    manager.getIRIMappers().add(mapper); 
    OWLOntology ontology = manager.createOntology(ontologyIRI); 
    OWLDataFactory factory = manager.getOWLDataFactory(); 
    OWLClass clsA = factory.getOWLClass(IRI.create(ontologyIRI + "#A")); 
    OWLClass clsB = factory.getOWLClass(IRI.create(ontologyIRI + "#B")); 
    OWLAxiom axiom = factory.getOWLSubClassOfAxiom(clsA, clsB); 
    AddAxiom addAxiom = new AddAxiom(ontology, axiom); 
    manager.applyChange(addAxiom); 
    manager.saveOntology(ontology); 
} 

Answer 2

public void addSubClass() throws OWLOntologyCreationException, OWLOntologyStorageException { 
    OWLOntologyManager manager = OWLManager.createOWLOntologyManager(); 
    OWLOntology ontology = manager.loadOntologyFromOntologyDocument(new File("pathToFile"); 
    OWLDataFactory dataFactory = OWLManager.getOWLDataFactory(); 

    OWLClass parentC = dataFactory.getOWLClass(IRI.create(baseIRI, "parent"); 
    OWLClass childC = dataFactory.getOWLClass(IRI.create(baseIRI, "child"); 
    axiom = dataFactory.getOWLSubClassOfAxiom(childC, parentC); 

    Axiom addAxiom = new AddAxiom(ontology, axiom); 

    manager.applyChange(addAxiom); 
    manager.saveOntology(ontology); 
}
