摘要
【目标】提出面向KOS版本演化的整合概念更新方法,促进多源异构词表整合系统动态发展。【方法】聚焦术语、同义词集合和优选术语三类知识单元,通过字符串精确匹配识别来源术语和优选术语变更模式;通过概念向量空间识别来源概念同义词集合变更模式;融合规则和相似度更新整合概念同义词集合和优选术语;以STKOS超级科技词表的医学类整合概念集及其重要来源MeSH和HUGO进行实验与准确性评估。【结果】新增术语更新同义归并准确率达94.96%,变更整合概念优选术语推荐准确率达99.91%。【局限】概念变更模式识别未考虑术语歧义性;多表同时更新时,变更概念术语归并准确率受词表部数和更新顺序影响。【结论】本文提出的整合概念自动更新策略可用于来源KOS版本升级引发的同义互操作系统概念升级。
[Objective]This paper proposes a method updating integrated concept for the version evolution of source Knowledge Organization Systems(KOSs),aiming to promote the dynamic development of the heterogeneous terminology integration system.[Methods]Our model focuses on terms,synonym sets and preferred terms of concepts.Firstly,we identified terms changing types and preferred terms changing modes of concepts in source KOSs by exact string matching.Then,we recognized their synonym sets changing patterns through concept vector space.Finally,we updated synonym sets and preferred terms of integrated concepts fusion rule and similarity.We also assessed the results yielded by our method using medical integration concept set of STKOS and its important sources,MeSH and HUGO.[Results]The synonymous merging rate of new term from source KOSs reached 94.96%,and the update accuracy of preferred term of changed integrated concepts reached99.91%.[Limitations]We did not consider ambiguity of the terms and the results were affected by the number of vocabulary and update order.[Conclusions]The proposed method can be applied to update concepts of synonymous knowledge organization systems because of their source KOSs evolution.
