ABSTRACT

This study aimed to identify emerging industrial root technologies from the unstructured text of journal papers, in order to establish a research and development (R&D) strategy. Hence, a structural topic model and topic matrix analysis were employed to evaluate the promising topics in Korean and international root technology papers, published from 2011 to 2019, from a domestic perspective. Subsequently, 75 topics in the main research domains of root technology were identified. Of these identified topics, five requiring leading R&D and five requiring follow-up R&D were selected based on priority: ‘Corrosion’, ‘device current–voltage characteristics’, ‘electrode’, ‘carbide alloy’, and ‘titanium alloy’ were determined to be the leading R&D topics, whereas ‘material applications’, ‘photocatalytic activity’, ‘additive manufacturing’, ‘ductility’, and ‘high-entropy alloy’ were determined to be the follow-up R&D topics. These results are significant because journal articles were used to determine emerging technologies according to the differences between the research published in Korean and international journals.

摘要

本研究旨在从期刊论文的非结构化文本中识别新兴的工业根技术，以建立研发 (R&D) 战略。因此，采用结构主题模型和主题矩阵分析，从国内角度评估 2011 年至 2019 年发表的韩国和国际根技术论文中的有前景的主题。随后，确定了根技术主要研究领域的75个主题。在这些确定的主题中，根据优先级选择了需要领先研发的五个和需要后续研发的五个：确定了“腐蚀”、“器件电流-电压特性”、“电极”、“碳化物合金”和“钛合金”成为领先的研发主题，而“材料应用”、“光催化活性”、“增材制造”、“延展性”和“高熵合金”被确定为后续研发课题。这些结果很重要，因为期刊文章被用来根据韩国和国际期刊上发表的研究之间的差异来确定新兴技术。
