Emotion-based planning evaluation method

It has been suggested by a number of researchers that emotional systems in agents might have great practical value. We propose a system that makes a decision about a plan, basing its judgment on emotion (i.e. pleasure/displeasure) extracted from knowledge, in an attempt to build a human-like computer agent, better able to communicate with users. We present an emotion-based plan evaluation method, and then provide the result simulated on naturally occurring short-story scenarios and show that plan evaluation based on artificial emotion generated by our method successfully matches the one based on human emotion.
