단어 리스트란 무엇을 의미하는가? | 다음 과정은 사전과 어휘 리스트 구축이다. 이 과정에서 구축되는 사전은 말뭉치(bag of words)와 같이 단어가 단순히 나열된 것이고, 단어 리스트는 단어의 출현 횟수를 기반으로 내림차순으로 정렬되어있는 것을 의미한다. 전처리를 통해 품사 태깅을 거친 텍스트는 긍정 형용사(positive adj. | |
영화 리뷰가 의견 분석이 가능한 데이터인 이유는 무엇인가? | 영화 리뷰는 감성분석 연구에서 자주 활용되는, 특정 대상(각 영화)에 대한 의견 분석이 가능한 데이터이다. 왜냐하면 리뷰는 영화를 먼저 본 사람들의 평가로써 아직 영화를 보지 않은 사람들에게 큰 영향을 미칠 수 있기 때문이다(Neelamegham and Chintagunta, 1999). 또한 영화 리뷰 데이터는 이용자가 직접 리뷰와 함께 평점(star rating)을 남길 수 있다는 특징이 있다. | |
오피니언 마이닝 혹은 감성분석은 무엇을 위해 사용되는가? | 누구나 제품 및 서비스를 이용하고 그 평가를 인터넷에 자유롭게 남길 수 있으며, 회사 및 조직은 이러한 고객의 리뷰, 즉 피드백을 이용하여 이익을 창출하기 위해 리뷰 데이터를 다방면으로 분석하는 시대이다. 오피니언 마이닝 혹은 감성분석은 텍스트 마이닝 기법중 하나로, 어떠한 사용자가 생성한 온라인 텍스트 속에 담긴 감성(sentiment), 정서(affect), 주관(subjectivity), 또는 감정(emotion)을 식별하기 위해 사용된다(Chen and Zimbra, 2010). 즉, 감성분석을 통해 이용자가 제품 또는 서비스로부터 어떠한 느낌을 받았는지 파악하기 위한 것이다. |
