This study presents a recently obtained social media data set based upon the case study of Electric Vehicles (EV) and looks to implement a sentiment analysis (SA) in order to gain insights. This study uses two methods in order to fully analyze the public’s sentiment on EVs. First, we implement a SA tool in which we used to extract the sentiment of comments. Next we labeled the data with these sentiments obtained and classified them. While performing classification we found the problem of dimensionality and also explored the use of feature selection (FS) models in order to reduce the data set’s dimensionality. We found that the use of three FS models (Chi Squared, Information Gain and ReliefF) showed the most promising results when used alongside a logistic and support vector machines classification algorithm. the contributions of this paper are in providing an real-world example of social media text analytics which can be adopted in many other areas of research and business. Moving forward researchers can use the methodological approach in this paper to further refine and improve their own case uses in text analytics.

본 연구는 전기자동차(EV)에 대한 소셜미디어 데이터를 기반으로 감성분석 (SA)과 속성선택 (FS)방법을 적용하 여 전기자동차에 대한 일반 사람들의 의견을 보다 효과적이고 정확히 예측할 수 있는 새로운 방법론을 제안한다. 구체 적인 방법은 다음과 같다. 첫째, 유튜브에 있는 전기자동차에 대한 일반 사람들의 의견을 추출하였다. 둘째, 분석의 효과성을 증대하기 위하여 카이 스퀘어, 정보획득량, 릴리프에프 등 세가지 속성선택 방법을 적용하였다. 그 결과 로지 스틱 회귀분석 및 서포트 벡터 머신 분류 기법에서 가장 의미있는 결과를 얻을 수 있다는 것이 확인되었다.
