Abstract[English]
An electronic device for generation of recommendations using trust-based embeddings is provided. The electronic device determines first correlation information of a first set of users associated with a first domain. The electronic device generates, based on the first correlation information, a first vector indicating a trust embedding of a first user with respect to the first set of users, in the first domain. The electronic device receives second correlation information associated with a second set of users associated with a second domain. The electronic device utilizes a Graph Attention Network model for the second correlation information to generate a second vector indicative of a trust embedding of the first user, with respect to the second set of users, in the second domain. The electronic device applies a recommendation model on the first vector and the second vector to recommend one or more items to the first user.[French]
L'invention concerne un dispositif électronique servant à générer des recommandations au moyen d'incorporations basées sur la confiance. Le dispositif électronique détermine des premières informations de corrélation d'un premier ensemble d'utilisateurs associés à un premier domaine. Le dispositif électronique génère, sur la base des premières informations de corrélation, un premier vecteur indiquant une incorporation de confiance d'un premier utilisateur par rapport au premier ensemble d'utilisateurs, dans le premier domaine. Le dispositif électronique reçoit des secondes informations de corrélation associées à un second ensemble d'utilisateurs et à un second domaine. Le dispositif électronique utilise un modèle de réseau d'attention graphique afin que les secondes informations de corrélation génèrent un second vecteur indiquant une incorporation de confiance du premier utilisateur par rapport au second ensemble d'utilisateurs, dans le second domaine. Le dispositif électronique applique un modèle de recommandation sur le premier vecteur et le second vecteur pour recommander un ou plusieurs articles au premier utilisateur.
