owl protege我如何描述一个只有一些属性的类? [英] owl protege how can I describe a class that has just some properties?
问题描述
是否有可能在protege中(因此在owl中)根据类是否具有某些属性来描述它?
Is it possible in protege (Thus in owl) to describe a class depending if it has some properties?
例如
我有一个类Home
,我想说每个具有property1
和property2
和property2
的实例都被视为该类的实例吗?
I have a class Home
, and I want to say that every instance that has property1
and property2
and property2
is considered an instance of that class?
推荐答案
假设您有一个 Duck 类,并且您想说的是,如果某人走路像鸭子,说话像鸭子,那么它是鸭子.您可以使用类公理来做到这一点:
Suppose you have a class Duck and you want to say that if something walks like a Duck, and talks like a Duck, then it is a Duck. You can do that with a class axiom:
((walksLike some Duck) and (talks like some 鸭)) SubClassOf 鸭
((walksLike some Duck) and (talksLike some Duck)) SubClassOf Duck
像这样的子类公理,其中左侧不仅是类名,而且是一个复杂的类表达式,被称为通用类公理.您可以在Protégé的 Active Ontology 标签下输入以下内容:
A subclass axiom like this, where the left hand side is not just a class name, but is a complex class expression, is called a General Class Axiom. You can enter these in Protégé, under the Active Ontology tab:
有关通用类公理的更多信息,您可能会发现 在左侧比较复杂:常规概念包含 有用.
For more about general class axioms, you may find Being complex on the left-hand-side: General Concept Inclusions useful.
