I have sample ontology to find near by restaurants.
I have made this ontology using Protege 3x and applied the following rule
Place(?p) ∧ Category(Chinese_Restaurants) ∧ hasCategory(?p,
Chinese_Restaurants) ∧ Selected(?s) → hasSelected(?s, ?p)
And when I am trying the same in Protege 4 or (Pellet + OWL API), I am
getting the following error in the rule part.
In Protege 4x - IllegalStateException: Node is null. Attempting to get node
In Pellet & OWL API - Error: Node is null. Attempting to get node for
Here Chinese_Restaurants is individual of Category class.
Please help me in explain this difference.
Thank you in advance.
