Question

让我们说我们有3个人

A = John (Father -> Man -> Thing) 
B = Bob (Child -> Thing)
C = Mary (Mother -> Woman -> Thing)

类

Child
Father -> Man
Mother -> Woman

对象属性

hasSpouse (symmetric)
isFatherOf (in range of child)

然后我只断言A

John hasSpouse Mary
John isFatherOf Bob

是否有可能推断玛丽是鲍勃的另一个？

下面的代码只能推断＆＃34;玛丽是母亲＆＃34;通过告诉＆＃34;母亲有一些父亲和＃34;

但是我怎么能在bob的Object属性断言中推断出断言呢？

通过添加新的对象属性，然后对它们应用一些条件？
