rdf – 使用数值数据表达式定义Protege类

我正在建立一个智能家庭本体.我现在有一个类层次结构：

我想给’RoomStatus’的子类定义.例如,我想定义当室温在18-22摄氏度范围内且湿度在40-50％范围内时,则房间温和.我试图在Protege中使用类表达式编辑器,但它不起作用.

我怎样才能实现这个定义？
提前致谢！

解决方法

Hatim’s answer可能适合你,但我认为最好不要在你不需要的时候使用等同的类公理,并避免将温和状态与特定的温度和湿度联系起来.毕竟,对于一个拥有温和身份的房间来说,具有温和身份意味着什么是非常不同的.

我建议使用General Class Axiom来说：

If a Room has a temperature and a humidity within the specified ranges,then the Room has a mild status.

作为一个阶级公理,那是：

Room and (hastemperature some integer[≥18,≤22]) and (hasHumidity some integer[≥40,≤50]) subClassOf (hasstatus value Mild_Status)

这几乎就是你在Protege中写的：

这是使用该公理的本体(在RDF / XML和TTL中)：
