摘要
提出了一种重用现有领域知识库知识构造新领域本体的方法.该方法充分利用了领域知识模型以及领域本体相互之间存在的语义相关性,从语义匹配的角度探讨了构造新领域本体的可能性.首先给出了领域本体的一种结构化定义,然后讨论了领域模型之间、领域本体之间存在的语义相关性,并给出了领域本体语义相关度的概念.以此为基础,重点讨论了基于生物种群进化方法构造新领域本体的选择、克隆、变异、杂交、合成和转基因方法.最后详细介绍了一个虚拟领域本体构造系统,并给出了具体分析实例.
A methodology is presented to construct virtual domain ontologies reusing other domain knowledge already available. This methodology uses the semantic relevance of existing domain models and domain ontologies, and proposes the possibility of building ontologies following the view of semantic match. Firstly, a structural definition of relevance degree is given. Based on the evolution of population, the domain ontologies constructing technologies in the terminology from genetics such as selection, clone, mutation, crossover, synthesis and transgenic are discussed. Finally, a VDO (virtual domain ontologies) constructing system is introduced, and a case study in the field of some hotels and travel agencies is demonstrated.
