Extracción de frases clave

La extracción de palabras clave es el proceso automatizado de extracción de palabras con mayor relevancia y expresiones del texto introducido. Ayuda a resumir el contenido y reconoce los temas principales.

El modelo de extracción de frases clave utiliza NLP y AA para encontrar información relacionada con los puntos principales del texto. Comprende el texto introducido no estructurado y devuelve palabras clave y frases clave (KP).

Las KP están formadas por sujetos y objetos sobre los que se habla en el documento. Cualquier modificador, como adjetivos asociados a estos sujetos y objetos, también se incluyen en la salida. Se incluyen puntuaciones de confianza para cada frase clave que indican la confianza sobre el KP. Las puntuaciones de confianza son un valor que va de 0 a 1.
