使用OWL API从本体文档加载本体

Question

我下载了OWL API maven项目并打开OWL API默认实现。我只想加载一个本体，但它给了我一个错误。

public static final IRI example_iri2 = IRI.create("http://mged.sourceforge.net/ontologies/MGEDOntology.owl");

public static void main(String[] arg) throws OWLOntologyCreationException {
    OWLDataFactoryImpl factoryImpl = new OWLDataFactoryImpl();
    ReadWriteLock readWriteLock = new NoOpReadWriteLock();
    OWLOntologyManagerImpl managerImpl = new OWLOntologyManagerImpl(factoryImpl, readWriteLock);
    OWLOntology ontology = managerImpl.loadOntology(example_iri2);
}

输出为：

        SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
    SLF4J: Defaulting to no-operation (NOP) logger implementation
    SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
    Exception in thread "main" org.semanticweb.owlapi.model.OWLOntologyFactoryNotFoundException: Could not find an appropriate factory to load ontology from ontology document: <http://mged.sourceforge.net/ontologies/MGEDOntology.owl>

我该如何解决这个问题呢？我试过了，但不起作用。

File file = new File("pizza3.owl");
OWLOntology ontology = managerImpl.loadOntologyFromOntologyDocument(file);

Answer 1

您创建的管理器需要设置。

推荐的方式是通过apibinding模块中的OWLManager。

推荐使用的依赖项是发行版或osgidistribution模块。
