摘　　要：本体匹配用于找到两个本体中元素间的映射关系,是数据库应用领域的一个重要问题.本文提出了一种基于描述逻辑的本体匹配方法,利用语义解释实现匹配.该方法首先利用多匹配器发现字面语义关系,并据此利用描述逻辑推理器推理元素相互间关系.借助概念包含推理设计了概念间关系的判定算法,可推理出各种对应关系,如等价、泛化、特化、相离、相交.该方法最终利用推理器RacerPro实现了本体匹配,最后通过实验证明了方法的有效性.Ontology matching produces correspondences between semanticaliy related entities of the ontologies and it plays a key role in many database application domains. Description Logics （DLs） is analyzed and a DLs-based ontology matching approach is proposed, and the approach achieves the matching by means of semantic interpretation. The muhi-matchers are used to produce the literal relations, according to which the semantic relations are reasoned by DLs reasoner. The algorithm of deciding ontology correspondence （such as equivalence, more general, less general, disjointness, overlapping） is presented, which is reasoned based on concept inclusion. The reasoner RacerPro is selected to deduce ontology mapping, and the experimental results demonstrate that the approach is feasible.
