摘要: OWL DL, a new W3C ontology language recommendation, is based on the expressive description logic $\mathcal{SHOIN}$ . Although consistency problem for known to be decidable, up now there has been no "practical" decision procedure, that is, goal-directed procedure likely perform well with realistic derived problems. We present such $\mathcal{SHOIQ}$ , slightly more than extending well-known algorithm $\mathcal{SHIQ}$ which basis several highly successful implementations.
