TL;DR
A new approach to phrase-level sentiment analysis is presented that first determines whether an expression is neutral or polar and then disambiguates the polarity of the polar expressions.
Abstract
This paper presents a new approach to phrase-level sentiment analysis that first determines whether an expression is neutral or polar and then disambiguates the polarity of the polar expressions. With this approach, the system is able to automatically identify the contextual polarity for a large subset of sentiment expressions, achieving results that are significantly better than baseline.

Predicting the semantic orientation of adjectives

This paper illustrates a sentiment analysis approach to extract sentiments associated with polarities of positive or negative for specific subjects from a document, instead of classifying the whole document intopositive or negative.

518 Citations2006Livia Polanyi, Annie Zaenen
It is argued that the current work in this area that concentrates mainly on the negative or positive attitude communicated by individual terms is incomplete and often gives the wrong results when implemented directly and proposes a simple, “proof of concept” implementation for some contextual shifters.

The data presented here show that cells with increased levels of the P-glycoprotein release ATP to the medium in proportion to the concentration of the protein in their plasma membrane, and measurements of whole-cell and single-channel currents with patch-clamp electrodes indicate that this protein serves as an ATP-conducting channel in the plasma membrane.

This work extends an existing procedure by re-interpreting it as a Naive Bayes model for document sentiment by incorporating additional derived features into the model and, where possible, using labeled data to estimate their relative influence.
