Sentiment Analysis
Sentiment Analysis is a way to understand how people feel about something by analyzing their written or spoken words. It's like having a tool that can read customer reviews, social media posts, or survey responses and tell whether people are happy, unhappy, or neutral about a product or service. Companies use this to understand their customers better, improve their products, and track their brand reputation. Think of it as automated emotional intelligence that helps businesses make better decisions based on how their customers really feel.
