We show that even changes in the polarity of a small number of words affect the overall accuracy by a few percent. Next, we propose a sentence-based analysis of the review sentiment, using the updated polarity lexicon for feature extraction.

The use of sentence-based analysis is aimed to bridge this gap. The remainder of this chapter is organized as follows.
