摘要
生物医学数据库到生物医学本体的语义映射是基于本体集成生物医学数据库系统的一个重要环节。而生物医学本体随着学科的发展不断演化,造成了集成系统不稳定。针对这个问题,本文在本体演化条件下,分析并发现了语义映射的变化规律,设计了对应的维护流程和维护方法,并通过计算维护收益率证明了该方法对映射的维护是有效性的,从而增强了集成系统在本体演化条件下的稳定性。
Semantic mapping from biomedical databases to biomedical ontology is a significant component of biomedical database integration system based on biomedical ontology.Biomedical ontology is evolving with development of the discipline,which is causing system instability.To address this issue,this paper analysed and found the changes of semantic mappings in the law under condi-tions in the biomedical ontology evolution,designed the maintenance process and the corresponding maintenance methods,and proved effectiveness of the method by calculating the benefit of the maintenance.
