Protege数据类型限制 [英] Protege datatype restriction

问题描述

我在本体中填充了定义Hour的数据.现在，我想对定义为int且值为0-23的特定数据类型(小时)进行限制.可以在白天和夜晚的小时划分上设置限制，例如，将天(小时最小6整数)和(小时最大17整数)划分为一天，并将其定义为对象Property isDay，但是问题是推论没有发生. 先感谢您， 艾略特

I have populated my ontology with data defining among others Hour. Now, I want to make a restriction on that specific datatype (hour) which is defined as int and has values from 0-23. The restriction would be set on the division of the hour according to day and night for example (hour min 6 int) and (hour max 17 int) for the day and that defined as object Property isDay, but the problem is the inferences does not happen. Thank you in advance, Eliot

推荐答案

您可以创建:DayEvent类作为:Event的子类，然后对要指定为以下范围的范围的dataType属性:hour声明限制.时段，例如6< = DayEvent hour< = 17，这种方式:

You can create a :DayEvent class as subclass of :Event and then declare restriction on the dataType property :hour for the range you want to specify as day slot, say 6 <= DayEvent hour <=17, this way:

:DayEvent rdf:type owl:Class ;

      owl:equivalentClass [
                     rdf:type owl:Restriction ;
                     owl:onProperty :hour ;
                     owl:someValuesFrom [ rdf:type rdfs:Datatype ;
                                     owl:onDatatype xsd:integer ;
                                     owl:withRestrictions ( 
                                                 [ xsd:minInclusive 6]
                                                 [ xsd:maxInclusive 17]
                                                )
                                         ]
                          ] ;

      rdfs:subClassOf :Event .

然后，所有具有dataType属性:hour且值在指定范围内的个人都将被推断为:DayEvent的成员.

Then all individuals with dataType property :hour having values within the specified range will be inferred as members of :DayEvent.

这至少可以与Protégé4.3和5，推理机HermiT，FaCT ++和Pallet一起使用.

This would work at least with Protégé 4.3 and 5, with reasoners HermiT, FaCT++ and Pallet.

等效的类定义将以Protégé语法显示，如下所示:hour some xsd:integer[>= 6 , <= 17].

The equivalent class definition will look in Protégé syntax like this: hour some xsd:integer[>= 6 , <= 17] .
