A set of personal characteristics that account for individual differences


The experience of emotion


Brief, intense affective state, usually triggered by a stimulus


Affective state that is non-intense, usually positive or negative


Situation-related factors that influence the decision


Recommender systems are algorithms that support human decision making by reducing the amount of available options to choose from. Understanding the factors that influence decision making is important for designing better recommender systems. Emotions and personality traits are psychological constructs that are linked to decision making and are used to improve recommendations. Emotions are psychological states that influence decisions. Personality is a human characteristic that accounts for individual differences.
