在 Protege 中处理负载本体中未声明的属性

编程问答 2022-05-03

问题描述

如何在java中使用owlapi重现Protege加载本体的方式？ 就像我使用时一样：

ontologyBase = ontologyManager.loadOntologyFromOntologyDocument(inFile);

结果：

[main] WARN org.semanticweb.owlapi.rdf.rdfxml.parser.Translators - Property http://www.example.com/individual/prp#keyPA is undeclared at this point in parsing: typing as OWLDataProperty
[main] WARN org.semanticweb.owlapi.rdf.rdfxml.parser.Translators - Property http://www.example.com/individual/prp#keyPB is undeclared at this point in parsing: typing as OWLDataProperty

未声明的属性被声明为 OWLDataProperty，但 Protege 加载本体导致将其声明为 OWLAnnotationProperty。

编辑： 本体：

<http://www.example.com/individual/prp#keyC> <http://www.w3.org/2002/07/owl#hasKey> <http://www.example.com/individual/prp#keyU> .
<http://www.example.com/individual/prp#keyU> <http://www.w3.org/1999/02/22-rdf-Syntax-ns#first> <http://www.example.com/individual/prp#keyPA> .

解决方法

从您的示例本体中解析出的公理如下：

HasKey(<http://www.example.com/individual/prp#keyC> () (<http://www.example.com/individual/prp#keyPA> <http://www.example.com/individual/prp#keyPB> ))
ClassAssertion(<http://www.example.com/individual/prp#keyC> <http://www.example.com/individual/prp#keyX>)
ClassAssertion(<http://www.example.com/individual/prp#keyC> <http://www.example.com/individual/prp#keyY>)
AnnotationAssertion(<http://www.example.com/individual/prp#keyPA> <http://www.example.com/individual/prp#keyY> <http://www.example.com/individual/prp#keyZA>)
AnnotationAssertion(<http://www.example.com/individual/prp#keyPA> <http://www.example.com/individual/prp#keyX> <http://www.example.com/individual/prp#keyZA>)
AnnotationAssertion(<http://www.example.com/individual/prp#keyPB> <http://www.example.com/individual/prp#keyY> <http://www.example.com/individual/prp#keyZB>)
AnnotationAssertion(<http://www.example.com/individual/prp#keyPB> <http://www.example.com/individual/prp#keyX> <http://www.example.com/individual/prp#keyZB>)

警告是关于临时输入为数据属性的未声明属性。解析器进行猜测，如果没有找到反驳类型猜测的公理，则类型将被保留。但在这种情况下，这不会发生（使用个人作为财产的对象），所以猜测被丢弃。

换句话说，您的代码与 Protege 完全一样解析本体。
