متن کاملThe HermiT OWL Reasoner
HermiT is the only reasoner we know of that fully supports the OWL 2 standard, and that correctly reasons about properties as well as classes. It is based on a novel “hypertableau” calculus that addresses performance problems due to nondeterminism and model size—the primary sources of complexity in state-of-the-art OWL reasoners.

Secondly, for those psychologists whose main focus is the cognitive mechanisms by which humans develop their particular suite of abilities, it is ...
