摘要
通过对领域本体参照下传统概念的3种语义相似度的计算模型研究,针对这3种计算模型的优缺点和领域本体所特有的性质,提出了一种改进的基于领域本体的概念语义相似度计算模型。实验结果表明,该计算模型通过定量的分析利用本体构词所描述的概念、特性之间的相似度,可以指导基于领域知识本体的语义查询中概念集扩充和查询结果排序,为概念之间的语义关系提供一种有效的量化。
Three kinds of traditional concept semantic similarity computation models based on the domain ontology is introduced. In allusion to the advantages and disadvantages of the three kinds of computation models, as well as the peculiar characteristic of domain ontology, an improved domain ontology-based concept semantic similarity computation model is put forward. It is proved that the computation model can be used to calculate the concepts and property similarity which is defined in ontology constructors, and help to extend the query concepts sets and rate query results in semantic retrieval system, and provide an effective quantification between concepts.
