摘要

文本挖掘技术可为各领域的研究信息提供有价值的见解。在本研究中，我们利用文本挖掘技术来确定 2012 年至 2022 年木材科学的研究趋势，重点关注在韩国和日本出版的代表性期刊。研究人员对从 SCOPUS 数据库中获取的《韩国木材科学与技术期刊》（JKWST，785 篇）和《木材科学杂志》（JWS，812 篇）的摘要进行了词频分析（具体而言，词频-反文档频率）和共现网络分析。结果表明，这两种期刊中与木材的物理和机械特性相关的词出现率都很高。此外，两国期刊中还经常出现与各国本土木材品种及其各自木材工业相关的词汇。CLT 是韩国和日本工程木质材料中的常见关键词。此外，关键词 "中密度纤维板"、"MUF "和 "GFRP "在韩国排名前 50 位。由此推断，日本的木材解剖学研究比韩国更为活跃。共现网络分析显示，与木材的物理和结构特征相关的词汇与木质材料有机地联系在一起。

Text Mining of Wood Science Research Published in Korean and Japanese Journals

Text mining techniques provide valuable insights into research information across various fields. In this study, text mining was used to identify research trends in wood science from 2012 to 2022, with a focus on representative journals published in Korea and Japan. Abstracts from Journal of the Korean Wood Science and Technology (JKWST, 785 articles) and Journal of Wood Science (JWS, 812 articles) obtained from the SCOPUS database were analyzed in terms of the word frequency (specifically, term frequency-inverse document frequency) and co-occurrence network analysis. Both journals showed a significant occurrence of words related to the physical and mechanical properties of wood. Furthermore, words related to wood species native to each country and their respective timber industries frequently appeared in both journals. CLT was a common keyword in engineering wood materials in Korea and Japan. In addition, the keywords “MDF,” “MUF,” and “GFRP” were ranked in the top 50 in Korea. Research on wood anatomy was inferred to be more active in Japan than in Korea. Co-occurrence network analysis showed that words related to the physical and structural characteristics of wood were organically related to wood materials.

期刊介绍： The Journal of the Korean Wood Science and Technology (JKWST) launched in 1973 as an official publication of the Korean Society of Wood Science and Technology has been served as a core of knowledges on wood science and technology. The Journal acts as a medium for the exchange of research in the area of science and technology related to wood, and publishes results on the biology, chemistry, physics and technology of wood and wood-based products. Research results about applied sciences of wood-based materials are also welcome. The Journal is published bimonthly, and printing six issues per year. Supplemental or special issues are published occasionally. The abbreviated and official title of the journal is ''J. Korean Wood Sci. Technol.''. All submitted manuscripts written in Korean or English are peer-reviewed by more than two reviewers. The title, abstract, acknowledgement, references, and captions of figures and tables should be provided in English for all submitted manuscripts.
