What is sentiment analysis?
Sentiment analysis or ‘opinion mining’ is the ability to determine the general feeling being conveyed by a communication. It is used to help assess whether the author may be conveying a positive, negative or neutral viewpoint. The technique uses natural language processing (NLP) to score words according to their meaning.
