在解析一组本体时,某些文件会给我以下错误,而其他文件则运行良好(请注意,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)

还有很多错误。知道如何解决这个问题吗?
更新:
加载本体的代码片段是:
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);
此错误表示您正在解析的其中一个本体不是有效的JSON / LD格式。
要解决这个问题,你必须做两件事:
如果使用的格式不是应该的格式,则需要在代码中指定格式 - 为此,您必须添加用于解析文件的代码片段。
