"Sentiment analysis" assesses the emotional tone behind a series of words, often used in data from social media, reviews, or customer feedback. This analysis employs natural language processing (NLP) and machine learning techniques to determine whether sentiments expressed are positive, negative, or neutral. Businesses use sentiment analysis to gauge consumer opinions about products or services, enabling them to adapt strategies accordingly. By understanding public sentiment, organizations can enhance customer engagement and improve their offerings, creating a more customer-centric approach to their business operations.
