One of IBM Watson's many talents is analyzing personality traits by looking at written text.

The supercomputer assesses traits based on the popular Big Five test, which rates subjects for extroversion, agreeableness, conscientiousness, neuroticism, and openness to experience. It can also identify different tones such as fear, joy, confidence, and openness. These skills have been used to do everything from assist customer service agents in analyzing how their phone calls went to providing dating tips.
