The more operators one includes in a logic and the more complicated the T-box having cycles, allowing non-atomic concepts to include each otherusually the higher the computational complexity is for each of these concrpt see Description Logic Complexity Navigator for examples.

A predicate nominative follows a linking verb and tells us what the subject is: The slow moving glacier wiped out an entire forest. It gave the villagers a lot of problems. This approach featured DL with limited expressiveness but relatively efficient polynomial time reasoning.
