One of the key problems to determining which emotion is expressed during a conversation is the subjectiveness of how people read emotions. We overcome this by using a simple Positive Activation – Negative Activation (PANA) model that focuses on actionable metrics such as energy (strong or weak) and how the emotional expression feels (positive or negative).
