Abstract
Concernant le domaine de la technologie de recommandation des mégadonnées, la présente demande décrit une méthode du moteur de traitement de flux de Flink pour des recommandations en temps réel, ainsi quun dispositif et un matériel informatique connexes. La méthode comprend le fait deffectuer un calcul de caractéristique à court terme sur une connexion à une file de messages en fonction dun dossier de modèles de calcul et le stockage des caractéristiques à court terme obtenues par le calcul dans une couche de stockage distribué, dans lequel la couche de stockage distribué stocke les caractéristiques à long terme obtenues préalablement et une caractéristique à court terme dun utilisateur recommandé potentiel de la couche de stockage distribué. La méthode comprend également le fait deffectuer une prédiction en temps réel en fonction dun dossier de modèle de prédiction et des caractéristiques à long terme et à court terme de lutilisateur recommandé potentiel, dans le but dobtenir dun résultat de prédiction de préférence de lutilisateur recommandé potentiel, lors de la réception dun événement de la file de messages, ainsi que lécriture du résultat de prédiction de préférence de lutilisateur recommandé potentiel dans la couche de stockage distribué.
