Sentiment analysis is a natural language processing technique used to determine whether textual data expresses positive, negative, or neutral sentiment. It can analyze large amounts of data like reviews, social media posts, and surveys to gauge public opinion and sentiment. While humans are still better at recognizing feelings, sentiment analysis tools are increasingly used by corporations to analyze customer feedback and understand markets by processing large amounts of user-generated content and identifying trends. Sentiment analysis goes beyond simple classification to comprehend meanings and insights about consumers.
