Keywords for academic papers are terms selected and created by the authors, and are, in general, considered a core element that summarizes and represents the papers’ content. This research analysed the ways in which the author keywords for academic papers are used in multiple disciplines. The Brillouin index was used for an analysis of interdisciplinarity. As a result, 63.7 percent of the keywords were shown to appear in only one area of study. These cannot be considered keywords with interdisciplinarity, but rather with topic specificity. In addition, the interdisciplinarity degree of 80 percent of the keywords were low, between 0 and 0.499. This indicates that the majority of author keywords for academic papers do not show interdisciplinarity. Meanwhile, certain author keywords had a fairly high interdisciplinarity degree. In this case, they can be seen as topics that are researched in multiple disciplines. It was revealed that the interdisciplinarity degree of author keywords in art/physical education are lower than in the humanities or social sciences. This suggests that the interdisciplinarity of author keywords is lower in art/physical education than in the humanities or social sciences.

韩国期刊作者关键词的跨学科研究特征

学术论文的关键词是作者选择和创建的术语，通常被认为是总结和代表论文内容的核心要素。本研究分析了学术论文作者关键词在多个学科中的使用方式。布里渊指数用于跨学科分析。结果，63.7% 的关键字仅出现在一个研究领域。这些不能被视为具有跨学科性的关键词，而是具有主题特异性的关键词。此外，80%的关键词跨学科度较低，在0到0.499之间。这表明学术论文的大多数作者关键词没有表现出跨学科性。同时，部分作者关键词具有较高的跨学科度。在这种情况下，它们可以被看作是在多个学科中研究的主题。研究表明，作者关键词在艺术/体育学科的跨学科程度低于人文学科或社会科学学科。这表明作者关键词的跨学科性在艺术/体育教育中低于人文或社会科学。
