OWL API V5从本地文件读取本体

Question

在链接：https://github.com/owlcs/owlapi/blob/version5/contract/src/test/java/org/semanticweb/owlapi/examples/examples.java的当前文档示例中，没有关于如何从本地文件加载本体的示例。只有从字符串加载它的方法。

在过去，当我使用OWL-APIVersion3时，以下代码工作得很好：

    OWLOntologyManager manager =OWLManager.createOWLOntologyManager();
    File file = new File (path);
    OWLOntology ont = manager.loadOntologyFromOntologyDocument(IRI.create(file));

但是，在这个版本中，前面代码的最后一行：

manager.loadOntologyFromOntologyDocument(IRI.create(file));

返回以下错误：

    Exception in thread "main" java.lang.NoSuchMethodError:

您离解决方案很近了：

final OWLOntologyManager manager = OWLManager.createOWLOntologyManager();
final OWLOntology ontology = manager.loadOntologyFromOntologyDocument(new File("/home/galigator/myLocalDir/aura.owl"));

只需使用new File而不是IRI.CREATE
