摘　　要：针对领域本体维护的重要性与合并本体存在的异构本体及不一致性错误等问题,提出了一种基于本体合并的领域本体自动维护方法,对相关实现过程作了详细介绍,重点给出了概念的相似性匹配算法。该算法通过计算概念的定义、实例、属性、关系及推理的相似度,得到了本体中概念之间的相似度。本文还探讨了本体不一致性的错误,分析了概念间的上下位关系、非通用关系及相关特性的不一致,并给出了解决方案。实验结果表明,该方法具有一定的实用性和可靠性,能够得到较正确的领域本体的维护结果,并能够解决相关不一致的错误。Aiming at the problems of domain ontology after construction,the importance of maintenance of domain ontology is pointed out.A method of automatic maintenance of domain ontology based on ontology merging is given.And the similarity matching algorithm of concept is presented.In the algorithm,the similarity of concepts between ontologies can be obtained through the similarity computation of concept definition,examples,attributes,relationships and reasonings.Additionly,ontological inconsistency error and its solution are deduced.And the experimental results show that the method has a certain practicability and reliability,and can obtain the correct domain ontology to maintain the results and to correct errors related to inconsistency.
