Extraction de clé-valeur (ID conducteur)

L'extraction des valeurs de clé peut être utilisée pour identifier les valeurs des clés prédéfinies dans la documentation d'un pilote pour les États-Unis ou le Royaume-Uni. Par exemple, si un ID inducteur inclut une date de sortie, une région et une date d'expiration, Document Understanding peut identifier ces valeurs et les retourner en tant que paire clé-valeur.

Les fonctionnalités prises en charge sont les suivantes :

  • Extraire les valeurs des paires clé-valeur prédéfinies
  • Polygones de liaison
  • Note de fiabilité
Les champs pris en charge sont les suivants :
