What is Sentiment Analysis?
Sentiment analysis (also known as opinion mining or emotion AI) uses natural language processing to determine the emotional tone behind a piece of text. It classifies text as positive, negative, or neutral, helping businesses understand customer opinions, monitor brand reputation, and improve products or services.
Our tool uses a lexicon-based approach, scoring words against a dictionary of positive and negative terms. While not as advanced as machine learning models, it's fast, transparent, and effective for basic sentiment detection.
