AKA, an AI development company, announced the issuance of PCT Patent (PCT/KR2018/006493, REG 1019653720000) for “Method of Determining Emotion of Computer Dialogue Agents.”
The patented technology involves a method for determining the emotions of computer dialogue agents.
Developed and based on a psychoevolutionary theory – Plutchik’s Wheel of Emotions – which classifies emotions to eight basic categories, AKA’s new patented technology makes it possible to determine the emotion of a computer dialogue agent by using dimensionality reduction techniques to map sentences into a color-emotion space.
To determine the emotional content of a sentence, the method employs dimensionality reduction techniques to map emotions as points in three-dimensional space. It uses sentences’ pleasure, arousal and dominance values, produced by a regression algorithm trained on in-house data, to project a point into the 3D coordinate system. The point is then mapped into a color-emotion space, as specified by Plutchik’s Wheel of Emotions. The final value of the emotion is determined by the point’s position in the color-emotion space: the type of emotion, the intensity of emotion, as well as a color to represent it. This information is finally used to determine the facial expression of Musio, the color of its heart, and as a parameter in guiding the dialogue between the user and Musio.
“We believe this is a very important patent received,” said Raymond Jung, CEO of AKA. “It will further strengthen our AI Engine, MUSE, with more accurate emotional expressions in human-robot communications.”
