Abstract

L'invention concerne un procédé et un appareil permettant d'obtenir un identifiant, ainsi qu'un support de stockage et un dispositif électronique. Le procédé consiste à : obtenir des identifiants correspondant à une opération prédéterminée à partir de multiples sources de données ; obtenir des identifiants initiaux parmi les identifiants en fonction des informations caractéristiques des identifiants et des mots caractéristiques prédéfinis ; déterminer les paramètres caractéristiques des identifiants initiaux en fonction d'un poids prédéfini et des informations caractéristiques ; et obtenir un premier identifiant cible parmi les identifiants initiaux, le premier identifiant cible étant un ensemble d'identifiants dont les paramètres caractéristiques sont supérieurs à un paramètre prédéfini dans les identifiants initiaux. La solution technique résout le problème technique dans l'état de la technique lié à la faible précision d'obtention d'un identifiant pour l'apprentissage.
