I can see the situation.

General speaking,  there doesn't exist any neat solution to this fuzzy issue.

Thinking:

What is the sufficient condition to make the assertion P2(R1, R2) true? even if under some precondition such as P1(R1, R2), subPropertyOf(P2, P1), R1 and R2 satifying the domain and range constraints of P2. 


Probability-based reasoning can be used to partially solve this problem, Or

Machine learning, Bayesian network, Neural Network, Or

Soft Computing Technique
