He only means that you will need to look for the value of the shared
property of common, not of tom...
suppose:
common, C
Tom, T
Jane, J
a sentence -> subject, predicate, object
Then you can have a model like
T, sex, male
J, sex, female
C, age, 22
But if you ask for,
T,age,?
You will have no answer, there isn't any sentence with T as subject and
age as predicate, you will need to look for...
T,type,x
x,age,?
Then you will get 22
Good luck,
Marc
