Leveraging the Dynamics of Leadership in Group Recommendation Systems (2503.12877v1)

Abstract: In the field of group recommendation systems (GRS), effectively addressing the diverse preferences of group members poses a significant challenge. Traditional GRS approaches often aggregate individual preferences into a collective group preference to generate recommendations, which may overlook the intricate interactions between group members. We introduce a novel approach to group recommendation, with a specific focus on small groups sharing common interests. In particular, we present a web-based restaurant recommendation system that enhances user satisfaction by modeling mutual interactions among group members. Drawing inspiration from group decision-making literature and leveraging graph theory, we propose a recommendation algorithm that emphasizes the dynamics of relationships and trust within the group. By representing group members as nodes and their interactions as directed edges, the algorithm captures pairwise relationships to foster consensus and improve the alignment of recommendations with group preferences. This interaction-focused framework ultimately seeks to enhance overall group satisfaction with the recommended choices.
