NTIS 바로가기한국태양에너지학회 논문집 = Journal of the Korean Solar Energy Society, v.40 no.4, 2020년, pp.1 - 11
The Journal of the Korean Solar Energy Society is the first journal in South Korea that adopts wind energy as one of its subjects. Since 2000, more than 140 papers on wind energy have been published in the journal, which accounts for 8.5% of the total publication. However, in recent years, the numbe...

풍력발전소 건설이 본격화는 언제부터 시작되었는가? | 5%에 해당된다. 2002년 재생에너지 발전차액지원제도(FIT; Feed-In-Tariff)가 도입됨에 따라 풍력발전소 건설이 본격화 되었고(Fig. 1) 이에 따라 풍력에너지 분야의 논문도 동반 증가하였으며, 2010년대에 이르러서는 전체 논문의 20%를 차지하는 핵심 분야로 성장하였다1). | |
하나의 기술용어가 여러 가지의 국문용어로 사용되는 등 일관성과 관련된 문제가 발생할 수 있는 이유는? | kr/)로부터 논문 제목, 키워드, 초록, 저자, 저자의 소속기관 등의 문서정보를 수집하되 저자와 저자 소속기관을 제외한 항목은 모두 영문정보를 수집하여 데이터베이스를 구성하였다. 기술용어의 국문 번역이 표준화되어 있지 못한 이유로 하나의 기술용어가 여러 가지의 국문용어로 사용되는 등 일관성과 관련된 문제가 발생할 수 있으며, 텍스트마이닝을 위한 공개된 코드와 라이브러리가 대부분 영문에 맞추어져 있기 때문에 영문으로 작업하는 것이 보다 효율적이며 정확한 텍스트마이닝 결과를 기대할 수 있을 것이라고 판단하였다. | |
주제분류의 전처리 과정으로 텍스트마이닝(text mining) 기법을 이용하여 단어빈도(word count)를 어떻게 계산하는가? | 주제분류의 전처리 과정으로 텍스트마이닝(text mining) 기법을 이용하여 단어빈도(word count)를 계산하였다. 즉, 논문 제목, 키워드, 초록으로부터 불용어(stopword)를 제외한 후 표제어(lemmatization) 및 어간추출(stemming)을 하고, 이들의 출현빈도를 셈하였다. 이때 ‘wind’, ‘turbine’, ‘speed’, ‘resource’, ‘complex’, ‘terrain’ 등의 단어는 ‘wind turbine’, ‘wind speed’, ‘wind resource’, ‘complex terrain’과 같이 완성된 주제단어로 조합하였으며 ‘data’, ‘method’, ‘calculate’, ‘increase’, ‘show’ 등과 같이 주제 분야를 특정하기 보다 보편적인 기술용어 또는 연구활동을 표현하는 명사와 동사는 주제단어에서 제외하였다. |
