Sentiment Analysis is a way for Artificial Intelligence (AI) to analyze and understand the underlying emotions and opinions of words and language. For example, if someone writes a review of a product and they say they love it, the AI can recognize that the person has a positive sentiment towards the product. On the other hand, if someone writes a review saying they hate the product, the AI can recognize that the person has a negative sentiment. This can be helpful for businesses to understand how people feel about their products or services and make improvements or changes based on customer feedback.
