    Abstract: In one embodiment, prior to similarity measure computation, concept expansion is applied to an original ontology to generate an expanded ontology having the original concepts plus one or more pseudo-concepts, wherein at least one original concept is defined using a hierarchy of (possibly transitive) properties. As a result, the similarity measure computation can produce results that are better than those produced using conventional techniques. In one implementation, the similarity measure computation involves combining two similarity results: a first similarity result corresponding to common semantics found in the two concepts and a second similarity result corresponding to dissimilar semantics found in the two concepts.

    Abstract translation: 在一个实施例中，在相似性测量计算之前，将概念扩展应用于原始本体以生成具有原始概念加上一个或多个伪概念的扩展本体，其中至少一个原始概念使用（可能是传递性的） ）属性。 因此，相似性测量计算可以产生比使用常规技术产生的结果更好的结果。 在一个实现中，相似性度量计算涉及组合两个相似性结果：对应于两个概念中发现的公共语义的第一相似度结果和对应于两个概念中发现的不相似语义的第二相似度结果。

    Abstract: In one embodiment, prior to similarity measure computation, concept expansion based on disjunctive normal form (DNF) decomposition and non-conventional reasoning is applied to an original ontology to generate an expanded ontology having the original concepts plus one or more pseudo concepts. As a result, the similarity measure computation can produce results that more accurately reflect a human point of view than convention techniques.

    Abstract translation: 在一个实施例中，在相似度测量计算之前，基于分离法则（DNF）分解和非常规推理的概念扩展被应用于原始本体以产生具有原始概念加一个或多个伪概念的扩展本体。 因此，相似性度量计算可以产生比常规技术更准确地反映人类观点的结果。
