A Model of Trust, Moods, and Emotions in Multiagent Systems and its Empirical Evaluation

A Model of Trust, Moods, and Emotions in Multiagent Systems and its Empirical Evaluation Report Title We study the interplay of moods, emotions, and trust in decisionmaking contexts characterized by commitments among agents. We develop a general approach representing the relationships among these concepts via a Bayesian network model. Our approach incorporates insights from the literature and provides a computational methodology for identifying improved Bayesian models. Based on observations from an empirical study, we motivate a re ned Bayesian model involving the above-mentioned concepts that goes beyond the relationships known in the literature. Our ndings include (1) the violation of a commitment a ects trust more than its satisfaction; (2) goal satisfaction a ects mood and emotion more than commitment satisfaction, but the outcome of a commitment a ects trust more than the outcome of a goal; and (3) an agent's prior mood and trust a ect whether it satis es its commitments.
