I am new in SQWRL and I have to add a new rule. I know how to execute a query.

My query to add a new rule is :

"pizza:Pizza(?p) ^ pizza:hasDiameter(?p, ?d) ^ swrlb:greaterThan(?d, 30) -> pizza:BigPizza(?p)"

But I have an error: Invalid SWRL atom predicate 'pizza:BigPizza'. And I don't know how to fix it because BigPizza is the new rule.

Is `pizza:BigPizza` a concept in your ontology already? – Henriette Harmse Jan 31 '18 at 11:51
