面向叙词表编制的生物、医学、农业间学科交叉现象研究

目的：通过研究叙词表覆盖学科的学科交叉现象及交叉程度，优化叙词表专业概念的收录比例，促进叙词表概念关系的构建。方法：基于传统的分类法体系——分类号，统计生物、医学、农业三大学科的文献产出数量及其拥有的多个分类号的文献数量，分析3个学科间的交叉现象及程度。结果：医学领域文献产出数最多，生物与农业两学科的交叉现象最明显。结论：研究与分析文献分类信息、学科交叉现象可以促进叙词表交叉概念的遴选。

Interdisciplinary phenomena in compilation of biological, medical and agricultural thesauruses

Objective To optimize the inclusion ratio of thesaurus concepts and promote the construction of relationships between thesaurus concepts by studying the interdisciplinary phenomena and extent in different disciplinary thesauruses. Methods The papers on biological, medical and agricultural sciences with several classification numbers were calculated according to the traditional classification system-classification number, the interdisciplinary phenomena and extent in biological, medical and agricultural sciences were analyzed. Results The largest number of papers was published in medical field and the interdisciplinary phenomena were most significant in biological and agricultural sciences. Conclusion Study and analysis of literature classification data and interdisciplinary phenomena can promote the selection of thesaurus concepts.
