What Is Sentiment Analysis?
Sentiment analysis is a feature that helps you quickly determine whether responses overall are generally positive or whether negative opinions are prevalent, without having to read through each open-ended text response. AI analyzes the expression and nuance of each response and automatically classifies it into one of three sentiments — positive, neutral, or negative — with results visualized in a gauge chart so you can see the overall tone at a glance.
