Abstract

Recently, big data analysis has drawn attention in various fields as it can generate value from large amounts of data and is also used to run political campaigns or predict results. However, existing research had limitations in compiling information about candidates at a high-level by analyzing only specific SNS data. Therefore, this study analyses news trends, topics extraction, sentiment analysis, keyword analysis, comment analysis for the 2017 presidential election of South Korea. The results show that various topics had been generated, and online opinions are extracted for trending keywords of respective candidates. This study also shows that portal news and comments can serve as useful tools for predicting the public's opinion on social issues. This study will This paper advances a building strategic course of action by providing a method of analyzing public opinion across various fields.

최근 빅데이터 분석은 대량의 데이터로부터 미래를 예측하여 가치를 창출할 수 있어 다양한 분야에서 주목받고 있으며, 정치 캠페인 운영이나 결과 예측에도 활용되고 있다. 하지만 기존의 연구는 특정 SNS 데이터만을 분석하여 후보자들에 대한 정보를 취합하는데 한계가 있었다. 이에 본 연구는 2017년 한국 대선 후보별 뉴스와 댓글을 수집하여 뉴스 생성 추이, 토픽 추출, 감성 분석, 키워드 분석, 키워드 감성 분석을 하였다. 분석 결과, 대선 후보 간 다양한 토픽들이 생성되는 것을 확인하였으며, 후보별 이슈가 되는 중점 키워드와 이에 대한 유권자들의 호응도가 추출되었다. 본 연구는 포털 뉴스에서 생성되는 대선 캠페인에 대한 동향을 마이닝 할 수 있게 했다는 점과 감성 분석을 통해 대권주자들에 대한 유권자들의 관심과 의견들을 정량화하여 수치화한 것에 의의가 있다. 본 연구가 여론 수렴의 도구적 방법을 제시함으로써 이를 바탕으로 전략적인 행동 방안을 도출할 수 있을 것을 기대한다.
