AI technique that determines the emotional tone of text.
What is Sentiment Analysis?
Sentiment analysis uses NLP to identify emotional tone in text—positive, negative, neutral, or more nuanced emotions. It's used to analyze customer feedback, social media, reviews, and any text where understanding opinion matters. Modern approaches use transformer models for nuanced understanding, capturing sarcasm, mixed sentiments, and aspect-based analysis (sentiment toward specific features). While imperfect, sentiment analysis at scale provides valuable insights for businesses, researchers, and content moderators.
