This paper presents a new approach to phrase-level sentiment analysis that first determines whether an expression is neu- tral or polar and then disambiguates the polarity of the polar expressions. With this approach, the system is able to automat- ically identify the contextual polarity for a large subset of sentiment expressions, achieving results that are significantly bet- ter than baseline.
