Keywords are not manually assigned, and we do not specifically search for certain words in reviews. Instead, we rely on Google’s Machine Learning (ML) to analyze the entire review. The algorithm identifies key topics within the review and assigns a sentiment score based on its understanding.
It's important to note that this process is powered by an ML algorithm, which means it is never expected to be 100% perfect. The system continuously learns and improves, but occasional inaccuracies may occur.
