猫头鹰用OneOf封闭世界 [英] owl closing the world with OneOf

问题描述

在下面的本体中，我试图通过使用OneOf使Boy成为Girl的补充，但是使用Fact ++或Hermit我无法通过查询Boy(Protege 5.2 DL查询)获得任何实例，有什么建议吗?

In the following Ontology I'm trying to make Boy the complement of Girl by using OneOf however using Fact++ or Hermit I'm unable to get any instances by querying for Boy (Protege 5.2 DL query), any suggestions?

:Bob rdf:type owl:NamedIndividual ,
              :Person .


:Mike rdf:type owl:NamedIndividual ,
               owl:Thing .


:Sarah rdf:type owl:NamedIndividual ,
                :Girl.

:Person rdf:type owl:Class ;
        owl:equivalentClass [ rdf:type owl:Class ;
                              owl:oneOf ( :Bob
                                          :Mike
                                          :Sarah
                                        )
                            ] .

:Girl rdf:type owl:Class ;
      owl:equivalentClass [ rdf:type owl:Class ;
                            owl:oneOf ( :Sarah
                                      )
                          ] ;
      rdfs:subClassOf :Person .

:Boy rdf:type owl:Class ;
     owl:equivalentClass [ owl:intersectionOf ( :Person
                                                [ rdf:type owl:Class ;
                                                  owl:complementOf :Girl
                                                ]
                                              ) ;
                           rdf:type owl:Class
                         ] ;
     rdfs:subClassOf :Person ;
     owl:disjointWith :Girl .

推荐答案

添加公理以使所有个体都不同可以解决斯坦尼斯拉夫提出的问题:

Adding an axiom to make all individuals as different solves the problem as suggested by Stanislav:

[ rdf:type owl:AllDifferent ;
  owl:distinctMembers ( :Bob
                        :Mike
                        :Sarah
                      )
] .
