一种基于参考本体的多本体映射方法

中文摘要: 随着领域内本体数量的不断增多，很多本体映射方法已经不适用于多本体映射任务。为此，提出一种基于参考本体的多本体映射方法 (multiple ontology mapping based on reference ontology，MOM RO)。在多本体映射过程中，方法MOM RO从源本体集合中提取共享概念集合并建立参考本体；然后利用参考本体来构建一个统一的向量空间模型；然后，将源本体中的概念表示成该模型中的向量，从而使用向量之间的欧氏距离来计算概念之间的相似度；最后，建立源本体之间的映射关系。实验结果表明，方法MOM RO可以有效地完成多本体映射的任务。
Abstract:A method of multiple ontology mapping based on reference ontology,called MOM RO,was put forward.In the process of mapping multiple ontologies,MOM RO extracted the shared concept set from sets of source ontologies,and created a reference ontology.Then,the reference ontology was used to create a uniform vector space model (VSM).Then concepts in source ontologies were represented as vectors in the VSM.In this way,the similarity of concepts was calculated by the Euclidean distance of the corresponding vectors.Finally,the mappings among source ontologies were created.Experimental results indicated that MOM RO performs encouragingly well when creating mappings among multiple ontologies.
