Abstract

As the dependence of technology on the economic structure increases, the importance of National Core Technology is increasing. However, due to the nature of the technology itself, it is difficult to determine the scope of the technology to be protected because the scope of the relation is abstract and information disclosure is limited due to the nature of the National Core Technology. To solve this problem, we propose the most appropriate literature type and method of analysis to distinguish important technologies related to National Core Technology. We conducted a pilot test to apply TF-IDF, and LDA topic modeling, two techniques of text mining analysis for big data analysis, to four types of literature (news, papers, reports, patents) collected with National Core Technology keywords in the field of Display industry. As a result, applying LDA theme modeling to patent data are highly relevant to National Core Technology. Important technologies related to the front and rear industries of displays, including OLEDs and microLEDs, were identified, and the results were visualized as networks to clarify the scope of important technologies associated with National Core Technology. Throughout this study, we have clarified the ambiguity of the scope of association of technologies and overcome the limited information disclosure characteristics of national core technologies.

경제 구조의 기술 의존성이 강해져 국가핵심기술의 중요성은 더욱 대두되고 있다. 하지만 기술 자체적 특성으로 인해 연관 범위가 추상적이고 국가핵심기술 고유의 특성상 정보공개가 제한적이기 때문에 보호대상이 될 기술의 범위를 정하는 것에 어려움이 있다. 이를 해결하기 위해 국가핵심기술과 연관성이 높은 중요 기술을 판별하는 데에 최적화 된 문헌 종류와 분석 기법을 제안하였다. 디스플레이 분야 국가핵심기술 키워드로 수집한 네 개 문헌종류(뉴스, 논문, 보고서, 특허) 데이터에 빅데이터 분석의 텍스트 마이닝 분석기법인 TF-IDF와 LDA 토픽 모델링을 적용하는 파일럿 테스트를 진행하였다. 그 결과로 특허 데이터에 LDA 토픽 모델링을 적용한 결과가 국가핵심기술과 연관성이 높은 중요기술을 추출하였다. OLED, 마이크로LED를 포함하여 디스플레이 전후방산업에 관련된 중요 기술을 판별 할 수 있었으며 이 결과를 관계망으로 시각화하여 국가핵심기술과 연관된 중요 기술의 범위를 명확히 하였다. 본 연구를 통해 기술이 가지는 연관범위의 모호성을 보다 명확히 하였으며, 국가핵심기술이 가지는 제한적인 정보공개 특성을 극복할 수 있다.
