Extraction d'expression clé

L'extraction d'expressions clés désigne le processus automatisé d'extraction des mots les plus pertinents et des expressions du texte d'entrée. Cette opération permet de résumer le contenu et d'identifier les principaux sujets.

Le modèle d'extraction de phrases clés utilise le traitement du langage naturel et l'apprentissage automatique pour rechercher des données clés relatives aux points principaux du texte. Il comprend le texte d'entrée non structuré et retourne des mots clés et des phrases clés.

Les phrases clés se composent de sujets et d'objets évoqués dans le document. Les modificateurs, tels que les adjectifs associés à ces sujets et objets, sont également inclus dans la sortie. Des notes de confiance sont incluses pour chaque phrase clé. Les notes de confiance sont des valeurs comprises entre 0 et 1.
