Abstract
본 연구는 과학계량학(scientometrics)을 활용하여 LED 및 광분야의 유망기술을 탐색하였다. 우선 Web of Science의 SCIE 논문 및 미국특허청(USTPO) 특허를 수집하여 키워드를 추출하였다. 추출된 키워드를 클렌징 과정을 통해 표준화하고, 동시단어 분석을 사용하여 LED 및 광분야의 논문과 특허 서지사항에 나타나는 정보간의 연합강도(association strength)를 측정함으로써 기술의 패턴 및 경향을 밝혀내었다. 그리고 LED 및 광분야의 역동적인 변화를 추적하기 위하여 전략적 다이어그램을 도출하였다. 이를 통해 LED 및 광분야의 미래 유망연구영역 및 기술도출의 객관적인 방법으로서 과학계량학의 가능성을 보여준다. The aim of this research is to map the intellectual structure of the field of LED and optics during the period of 2000-2009. We utilize the scientometric tool of co-word analysis to reveal patterns and trends in the LED and optics field by measuring the association strengths of keywords (or IPCs). Data were collected from Science Citation Index Expanded (SCIE) and United Stated Patent and Trademark Office (USTPO) for the period of 2000-2009. Keywords were extracted from abstracts and further standardized using thesaurus. In order to trace the dynamic changes of the LED and optics field, the whole 10-year period was separated into two consecutive periods: 2000-2004 and 2005-2009. The results show that the LED and optics field has some established research themes and it also changes to embrace new themes.
