【目的/意义】针对叙词表概念遴选与词间关系构建的现状,以交叉学科方法研究概念在不同时间节点的变化规律。【方法/过程】假设学科领域内概念的词频随时间变化规律遵循生态学中Logistic种群增长规律,对专业领域文献中概念出现的频次进行统计,依据单个概念的成熟周期给出选词判断标准与词间关系的强弱判断依据。【结果/结论】发现在跨学科视角下,可以通过词频关系为新文献环境词表词间关系的构建提出参考意见。
[Purpose / Significance] According to the current situation of the construction of the concept selection of the thesaurus and the relationship between the words, the interdisciplinary approach is used to study the changing rules of concepts at different time points. [Method / Procedure] Assuming that the word frequency of concepts in disciplines varies with time according to the law of Logistic population growth in the field of ecology, statistics are made on the frequency of appearance of concepts in the field of professional literature, and the criterion of word selection is given according to the mature period of a single concept. The relationship between the strength of judgments. 【Result】 The research found that under the perspective of interdisciplinary perspective, we can provide suggestions for the construction of the relationship between the new vocabulary and the environment through word frequency relationship.
