Artificial intelligence won’t be truly convincing until it can understand emotions. What good is a robot that can’t understand the nuances of what you’re really saying? IBM thinks it can help, though. It just gave Watson an upgrade that includes a much-improved Tone Analyzer. The AI now detects a wide range of emotions in your writing, including joy or sadness. If you tell everyone that you’re fine when you’re really down in the dumps, Watson should pick up on that subtle melancholy. Watson is also better at spotting social tendencies like extroversion, and studies whole sentences (important for context) rather than looking at individual words.
