Abstract
본 논문에서는 감성 점수가 명시적으로 부여되지 않은 온라인 영화평에 대해 자동으로 감성을 분류하는 방법을 제안한다. 긍정이나 부정과 같은 감성 극성 분류를 위해 문자열 커널의 확장 모델인 음절 커널에 기반한 지지벡터기계를 분류기로 사용한다. 실험을 통하여 띄어쓰기나 철자 오류 같은 문법적인 오류가 빈번한 온라인 영화평에 대한 감성 분류에서 제안한 음절 커널 방법이 효과적임을 보인다. In this paper, we present an automatic sentiment classification method for on-line movie reviews that do not contain explicit sentiment rating scores. For the sentiment polarity classification, positive or negative, we use a Support Vector Machine classifier based on syllable kernel that is an extended model of string kernel. We give some experimental results which show that proposed syllable kernel model can be effectively used in sentiment classification tasks for on-line movie reviews that usually contain a lot of grammatical errors such as spacing or spelling errors.
