Sentiment Analysis with Grammatical Tags
A sentiment analysis system can first use a linguistic tagger to mark parts of speech in a review, such as adjectives and nouns, and then pass that annotated text to a sentiment classifier. This extra structure helps the classifier focus on opinion-bearing words like "excellent" instead of treating every word as equally important.
