OWL限制-定义仅包含具有特定属性值的属性的类 [英] OWL restrictions - defining classes that only contains properties with a specific property value

问题描述

我目前正在与OWL合作，尤其是在限制方面.我正在尝试创建一个执行以下操作的查询:

I'm currently playing a bit with the OWL and especially with restrictions. I'm trying to create a query that does the following:

假设我有一个具有属性电影"的电影院"类(其中包含电影"类型的对象). 电影"类包含一个名为流派"的属性.现在，我想创建一个仅包含类型为动作"的电影的ActionCinemas类.

Suppose that I have a class 'Cinema' that has a property 'movies' (that contains objects of type 'Movie'). The class 'Movie' contains a property named 'genre'. Now I want to create a class ActionCinemas that only has movies with the genre 'action'.

我真的不确定如何执行此操作.我当时正在考虑使用交叉点或基数来做某事，但我不确定.

I'm really not sure how to do this. I was thinking about doing something with intersections or the cardinality but I'm not sure of that.

有人可以帮我吗?

推荐答案

您需要组合allValuesFrom限制和hasValue限制，例如:

You need a combination of an allValuesFrom restriction and a hasValue restriction, e.g like this:

海龟语法:

 my:ActionCinema a owl:Class ;
      rdfs:subClassOf my:Cinema,
                      [ a owl:Restriction; 
                        owl:onProperty my:hasMovie ;
                        owl:allValuesFrom [ a owl:Restriction ; 
                                            owl:onProperty my:hasGenre ;
                                            owl:hasValue my:Action ]
                      ] .

曼彻斯特OWL语法:

Class: ActionCinema
   SubClassOf: Cinema that hasMovie only ( hasGenre value Action )
