摘要
由于时间、地点、目的、知识以及构造者的不同,导致即使对同一问题,本体的构造也会有很大的差异,这样就造成本体间很难共享和重用。而本体映射是解决本体异构、在不同本体间建立语义关联的一种有效的方法。针对目前本体映射方法中概念相似度计算所存在的问题,本文提出一种综合映射方法,即先通过分类将大本体划分为若干小型的本体树,再对小本体树分别从概念名称、实例及结构分别计算概念相似度并综合,这样大大简化了相似度计算的复杂度,也提高了准确性、全面性。最后以国防工业本体和中文飞机本体为例做了实验并对算法做了分析。
Due to the difference in time,locations,purposes,knowledge and constructers,the construction of ontology will also be very different even for the same issue.So it will be very difficult for inter-ontology sharing and reuse.Ontology mapping is an effective method of solving the heterogeneity of ontology and setting up semantic relevance.Aiming at the current problems in the computing similarity of concepts,this paper proposes a comprehensive method of ontology mapping：firstly,it divides large ontology into a number of small ontology trees through the classification;then it computes concept name,instance,and structure of the small ontology trees separately and integrates the results;lastly,it takes the national defense industry ontology and the Chinese plane ontology as an example to do an experiment and analyses the algorithm.
