在解析一組本體時，一些文件給了我以下錯誤，而其他文件運行良好（請注意，我使用的是 OWL API 5.1.6）：uk.ac.manchester.cs.owl.owlapi.OWLOntologyManagerImpl.loadOntology(OWLOntologyManagerImpl.java:1033)    uk.ac.manchester.cs.owl.owlapi.OWLOntologyManagerImpl.loadOntology(OWLOntologyManagerImpl.java:933)    uk.ac.manchester.cs.owl.owlapi.OWLOntologyManagerImpl.loadImports(OWLOntologyManagerImpl.java:1630)....Could not parse JSONLD        org.eclipse.rdf4j.rio.jsonld.JSONLDParser.parse(JSONLDParser.java:110)    org.semanticweb.owlapi.rio.RioParserImpl.parseDocumentSource(RioParserImpl.java:172)    org.semanticweb.owlapi.rio.RioParserImpl.parse(RioParserImpl.java:125)....Stack trace:org.eclipse.rdf4j.rio.RDFParseException: unqualified attribute 'class' not allowed [line 3, column 65]        org.semanticweb.owlapi.rio.RioParserImpl.parse(RioParserImpl.java:138)    uk.ac.manchester.cs.owl.owlapi.OWLOntologyFactoryImpl.loadOWLOntology(OWLOntologyFactoryImpl.java:193)    uk.ac.manchester.cs.owl.owlapi.OWLOntologyManagerImpl.load(OWLOntologyManagerImpl.java:1071)    uk.ac.manchester.cs.owl.owlapi.OWLOntologyManagerImpl.loadOntology(OWLOntologyManagerImpl.java:1033)    uk.ac.manchester.cs.owl.owlapi.OWLOntologyManagerImpl.loadOntology(OWLOntologyManagerImpl.java:933)    uk.ac.manchester.cs.owl.owlapi.OWLOntologyManagerImpl.loadImports(OWLOntologyManagerImpl.java:1630)....以及許多類似的錯誤。知道如何解決這個問題嗎？更新：加載本體的片段是：File file = new File("C:\\vocabs\\" + Ontofile.getName());OWLOntologyManager m = OWLManager.createOWLOntologyManager();OWLOntology o;o = m.loadOntologyFromOntologyDocument(file);OWLDocumentFormat format = m.getOntologyFormat(o);OWLOntologyXMLNamespaceManager nsManager = new OWLOntologyXMLNamespaceManager(o, format);
