Abstract

Despite of correlation between climate changes and food-related information, it is still not easy for many users to get access to the information with interest. This study investigated how much climate change and food-related information are correlated with each other and how often they are exposed through frequency and correlation analysis on news articles on the internet portals. Through analysis on the frequency of climate change and food-related news articles, this study was able to figure out how often they are exposed at the same time by the internet news portals. In addition, a total of 59 correlation rules regarding the climate change and food-related vocabularies were derived from these news articles using the climate change and food-related glossaries. Then, a correlation between certain climate change-related and food-related words was analyzed in order to package the related words.

기후변화와 식품 관련 정보가 유기적인 관련이 있음에도 불구하고, 사실상 현실에서는 사용자들이 직접 그 관련성에 대한 관심을 가지고, 해당 정보에 대한 접근이 용이하다고 말하기는 어렵다.본 연구는 실제 사용자들이 직접적으로 노출되는 인터넷 포털 사이트의 뉴스 기사에 대한 빈도분석 및 연관관계 분석을 통해 기후변화 및 식품 관련 정보가 어느 정도의 연관성을 가지고 얼마나 자주 나타나고 있는지에 대해 파악하였다. 또한 추출된 기후변화 및 식품 관련 뉴스를 대상으로 기후변화 용어 사전과 식품 관련 용어 사전을 활용하여 기후변화 관련 용어와 식품 관련 용어의 총 59개의 연관관계 규칙을 도출함으로써, 특정 기후변화 관련 용어가 어떠한 식품 관련 용어와 연관관계를 갖는지 파악하여, 추후 두 용어를 패키징해 제공할 수 있는 발판을 마련하였다.
