基于生态学视角的叙词表概念稳定性研究

Research on Concept Stability of the Thesaurus Based on Ecology

[目的/意义]在叙词表的新建与更新维护过程中,提前确定概念数量和概念间关系的大致情况,是词表构建的重要工作。[方法/过程]借鉴生态学原理,从生态位、食物网和冗余机制三个方面说明叙词表概念稳定性的形成原因,并选取MeSH医学主题词表和《核科学技术叙词表》,分别统计概念的数量变化和概念间关系的变化情况进行实证。[结果/结论]从生态学角度对叙词表概念的稳定性进行了解释,同时证明叙词表概念存在数量稳定性和关系稳定性,并依据此对叙词表的更新维护提出一定建议。

[Purpose/Significance] In the process of construction and update of the thesaurus,it is possible to determine the approximate extent of the number of concepts and the relationship between concepts in advance,which is an important part of the construction of the thesaurus.[Method/Process] Based on the ecology principles,this paper explains the reasons for the stability of the thesaurus concept from three aspects: niche,food network and redundancy mechanism. The MeSH medical thesaurus and the Nuclear Science and Technology Thesaurus are selected to demonstrate the change of the number of concepts and the relationship between concepts.[Result/Conclusion] The stability of the thesaurus concept is explained from the view of ecology. At the same time,it is proved that the thesaurus concept has the stability of quantity and relationship,and some suggestions on the maintenance of the thesaurus are given accordingly.
