使用OWL API保存小球推理

Question

我正在使用带有OWL API的最新版本的颗粒推理器:

 OWLOntologyManager manager=OWLManager.createOWLOntologyManager();
 OWLOntology fist_ontology=manager.loadOntologyFromOntologyDocument.........
 ................
 OWLOntology last_ontology=manager.loadOntologyFromOntologyDocument..........
 reasoner=PelletReasonerFactory.getInstance().createReasoner(last_ontology);
 manager.addOntologyChangeListener(reasoner);

管理器装载了几个本体。现在我需要在一个文件中保存Pellet对加载了管理器的所有本体所做的所有推断，但是我找不到任何示例。有人能帮我吗?

我已经解决了:

List<InferredAxiomGenerator<? extends OWLAxiom>> gens = new ArrayList<>();
         gens.add(new InferredSubClassAxiomGenerator());  
         gens.add(new InferredClassAssertionAxiomGenerator());
         gens.add( new InferredDisjointClassesAxiomGenerator());
         gens.add( new InferredEquivalentClassAxiomGenerator());
         gens.add( new InferredEquivalentDataPropertiesAxiomGenerator());
         gens.add( new InferredEquivalentObjectPropertyAxiomGenerator());
         gens.add( new InferredInverseObjectPropertiesAxiomGenerator());
         gens.add( new InferredObjectPropertyCharacteristicAxiomGenerator());
         gens.add( new InferredPropertyAssertionGenerator());
         gens.add( new InferredSubDataPropertyAxiomGenerator());
         gens.add( new InferredSubObjectPropertyAxiomGenerator());
         InferredOntologyGenerator iog = new InferredOntologyGenerator(reasoner, gens);
         OWLOntology infOnt = manager.createOntology();
         iog.fillOntology(datafactory, infOnt);
         manager.saveOntology(infOnt,new RDFXMLDocumentFormat(),IRI.create(new File("D://file.owl"))); 

Answer 2

public void flushToFile() {
        reasoner.flush();
        //System.out.println(reasoner.isEntailed(ax5));
        InferredOntologyGenerator gen = new InferredOntologyGenerator(reasoner);
        gen.fillOntology(factory, newOntology);
        try {
            manager.saveOntology(newOntology, new FileOutputStream(new File("D:\XYZ\OutputNew.owl")));
        } catch (OWLOntologyStorageException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

你可以使用这个api来保存本体到一个文件。此外，您可以通过以下链接了解有关工作的详细信息:-告诉关于颗粒推理器的工作和swrl规则
