摘要 SHOIQ(D)是一种表述能力较强的本体知识表示语言。一致性检测是本体推理的核心任务之一,其它推理任务都可以等效地转换为一致性检测问题。本文在对Tableau演算研究的基础上,通过引入回跳和布尔约束传播优化技术,提高算法推理效率,并以此算法为核心,给出基于SHOIQ(D)语言的本体一致性检测推理机的总体设计方案及实现。 SHOIQ(D) is a language of knowledge presentation with powertul expressive capabilities to describe Ontology. Consistency checking is a key inference problem of Ontology reasoning, in which other inferences can also be reduced. Tableau calculus and its optimization technologies are studied in this paper. Rebound and the Boolean constraint propagation optimation are brought into SHOIQ(D) to increase the reasoning efficiency. Finally, the reasoner of consistency checking is implemented by using the algorithm of SHOIQ(D) -based ontology.
