Java 使用OWLAPI获取本体中两个对象的属性值交集

我对OWLAPI还不熟悉，并尝试尝试使用它。我在protege中创建了一个简单的本体，在eclipse中使用OWLAPI创建了一个交互应用程序。本体结构如下：-

----------------------------------------------------------------------------------------  
 Class                Object       (Data Property)StringValue  ObjectProperty relatedTo    
----------------------------------------------------------------------------------------  
 WordString             WS1                    "One"                   DS1
                        WS2                    "Two"                   DS2
                        WS3                    "Three"                 DS3

 DigiString             DS1                    "1"  
                        DS2                    "2"  
                        DS3                    "3"  
----------------------------------------------------------------------------

我想为DS1检索对象WS1，为DS2检索对象WS2，即在提供字符串“1”、“2”等时，我的代码应该分别检索“1”、“2”。我还没有在网上遇到过这种类型的相关代码。如有任何帮助，将不胜感激。提前感谢。

以下示例（OWLAPI 4）应该会有所帮助：

    OWLOntology o = ... your ontology here
    String ns = "http://localhost:3030/DigiWord.owl#";
    OWLDataFactory df = o.getOWLOntologyManager().getOWLDataFactory();
    OWLObjectProperty relatedto = df.getOWLObjectProperty(IRI.create(ns + "relatedTo"));
    OWLDataProperty stringValue = df.getOWLDataProperty(IRI.create(ns + "stringValue"));
    SimpleRenderer renderer = new SimpleRenderer();
    for (OWLNamedIndividual i : o.getIndividualsInSignature()) {
        for (OWLLiteral lit : EntitySearcher.getDataPropertyValues(i, stringValue, o)) {
            System.out.println(i + " has values " + renderer.render(lit));
        }
        for (OWLIndividual related : EntitySearcher.getObjectPropertyValues(i, relatedto, o)) {
            for (OWLLiteral lit : EntitySearcher.getDataPropertyValues(related, stringValue, o)) {
                System.out.println(i + " related to " + related + " which has values " + renderer.render(lit));
            }
        }
    }

编辑：要查找查询的匹配项，请执行以下操作：

    for (OWLNamedIndividual i : o.getIndividualsInSignature()) {
        for (OWLIndividual related : EntitySearcher.getObjectPropertyValues(i, relatedto, o)) {
            for (OWLLiteral lit : EntitySearcher.getDataPropertyValues(related, stringValue, o)) {
                if(lit.getLexicalForm().equals("1")){
                    for (OWLLiteral lit : EntitySearcher.getDataPropertyValues(i, stringValue, o)) {
                        System.out.println(i + " has values " + renderer.render(lit));
                    }
                }
            }
        }
    }

你的本体是什么样子还不是很清楚。你能在曼彻斯特或函数语法中添加公理吗？@mikrohelen先生，我已经放置了完整的本体论。谢谢，每样东西都印出来了。我的问题是访问单个类。例如，如果我从控制台输入“1”。应用程序应打印“一”。这意味着首先访问DS1，因为其字符串值为1，然后检索WS1，因为DS1与WS1相关，最后将打印“一”。请帮助这一点，因为没有与文档和谷歌运气。非常感谢。您需要的是将文字的值与个人匹配。我的意思是，在我的示例中，您需要找到

I

，其中lit的词法形式为“1”，并获取该个体的其他stringValue值
