Sentiment analysis, also known as opinion mining, is a natural language processing technique that determines and classifies the sentiment expressed in textual data, such as social media posts, reviews, or comments. It assigns sentiments like positive, negative, or neutral to analyze public opinions and reactions.
Businesses use sentiment analysis to gauge customer satisfaction, brand reputation, and market trends. For example, a company may use sentiment analysis to monitor social media for customer feedback and track how people feel about their products and services.
