Extraction d'expressions clés

L'extraction de mots-clés est le processus automatisé d'extraction des mots les plus pertinents et des expressions du texte saisi. Ce processus permet de récapituler le contenu et de reconnaître les principaux sujets.

Le modèle d'extraction d'expressions clés utilise le traitement du langage naturel et l'apprentissage automatique pour rechercher des informations relatives aux principaux points du texte. Il comprend le texte saisi non structuré, et renvoie les mots-clés et les expressions clés.

Les expressions clés se composent de sujets et d'objets qui sont abordés dans le document. Tous les modificateurs, tels que les adjectifs associés à ces sujets et objets, sont également inclus dans le résultat. Les scores de confiance sont inclus pour chaque expression clé qui indique la confiance à l'égard de l'expression clé. Les scores de confiance sont une valeur comprise entre 0 et 1.
