Sentiment Analysis
Sentiment Analysis is a technology that helps computers understand and measure the emotions and opinions in text, like customer reviews, social media posts, or survey responses. Think of it as an automated way to figure out if people are saying positive, negative, or neutral things about a product, service, or topic. Companies use this to understand how customers feel about their products, track brand reputation, and make business decisions. It's part of the broader field of Natural Language Processing (NLP), which helps computers understand human language. When you see this on a resume, it usually means the person has experience with tools and programs that can automatically process large amounts of text to understand public opinion or customer feedback.
