What is Sentiment Analysis?

Sentiment analysis represents the computational study of an individual's opinions, attitudes or emotions in relation to a given subject. This subject can represent an individual or group of individuals, an event or a topic. There are 3 types of sentiment analysis levels:

• document level - assumes the existence of a general opinion, usually positive or negative and expressed by the author of the document, on a specific subject.
• sentence level - used to determine the polarity of a sentence, usually subjective. Very similar to the document level implementations.
• aspect level - has the objective of recognizing all sentiments contained in an opinion and all the aspects to which they refer.
