Abstract
빅 데이터 분석기법 중 비정형데이터 분석기법인 텍스트 마이닝 기법을 이용하여 기후변화 관련식품분야 논문 초록에서 용어들의 출현빈도를 분석하였다. 이를 위하여 용어-문헌 행렬을 만들고, 용어들간의 비유사성 측도를 바탕으로 계층적 군집분석기법을 적용하여 문서들을 군집화하였다. 군집화된 문서들간의 상호 연관성과 군집별로 특정용어의 빈도를 파악하여 문서군집을 특정주제별로 분류하였다. 이러한 연구를 통하여 식품분야의 기후변화 관련 논문들의 추세와 관심주제어를 파악할 수있었으며, 향후 기후변화 적응 및 대응 체계 로드맵 작성 시 연구 개발 기초 자료로 활용할 수 있을 것이다.

Research articles in food related to climate change were analyzed by implementing a text-mining algorithm, which is one of nonstructural data analysis tools in big data analysis with a focus on frequencies of terms appearing in the abstracts. As a first step, a term-document matrix was established, followed by implementing a hierarchical clustering algorithm based on dissimilarities among the selected terms and expertise in the field to classify the documents under consideration into a few labeled groups. Through this research, we were able to find out important topics appearing in the field of food related to climate change and their trends over past years. It is expected that the results of the article can be utilized for future research to make systematic responses and adaptation to climate change.
