Social media sentiment analysis is a powerful tool for understanding people’s opinions online. Businesses, governments, and organizations use it to track what people are saying. It helps brands manage their reputation, improves customer service, and identifies trends.
With millions of posts daily, analyzing social media manually is impossible. That is where artificial intelligence (AI) and natural language processing (NLP) come in. These technologies process large amounts of data to determine if social media conversations are positive, negative, or neutral.
In this guide, we will explore how sentiment analysis works, its benefits, challenges, and future trends.
