OWL本体(具有属性限制) [英] OWL Ontology (giving property restrictions)

问题描述

我目前正在研究OWL本体，我对财产有疑问.

I am currently working on the OWL Ontology I have a question in regard to property.

坦率地说，我并不真正了解对类进行财产限制的重要性.

To be frankly saying, I don't really see the importance of giving a property restriction to class.

例如，

产品(类)有制造商(属性)一些制造商.

Product (class) has manufacturer (property) some Manufacturer.

在这种情况下，这意味着一种产品至少具有一个制造商.

In this case this means that one product has at least one manufacturer.

但是，为什么不这样做呢?

However, then why not just do object property assertions by

塑料模型(产品的个体)具有制造商(对象属性)DOCOMO(制造商的实例)吗?

a plastic model (an individual of the product) has manufacturer (object property) DOCOMO (an instance of the manufacturer) ?

我必须同时做这两个吗?如果我不做第一件事，我的理由就是没有问题.为什么我必须同时做这两项?

Do I have to do both? enve if I don't do the first thing, the reasoner says there is no problem. Why Do i have to do both?

推荐答案

财产限制断言了一组个人的某些东西，而不仅仅是一个个人.考虑属性限制:

Property restriction asserts something about a set of individuals, not just a single individual. Consider the property restriction:

Every man likes a woman. (i.e. "man subClassOf like some woman")

vs属性声明:

John likes Mary. (i.e. "{John} subClassOf like some {Mary}")

其中{John}和{Mary}是具有单个个体的类，而man和woman是具有0个或更多个体的类.

where {John} and {Mary} are classes with a single individual, but man and woman are classes with 0 or more individuals.
