Estrazione frase chiave

L'estrazione delle parole chiave è il processo automatico di estrazione delle parole più rilevanti e delle espressioni dal testo di input. Aiuta a riassumere il contenuto e riconosce gli argomenti principali.

Il modello di estrazione delle frasi chiave utilizza NLP e ML per trovare approfondimenti relativi ai punti principali del testo. Comprende il testo di input non strutturato e restituisce parole chiave e frasi chiave (KP).

I KP sono costituiti da soggetti e oggetti di cui si parla nel documento. Nell'output vengono inclusi anche tutti i modificatori, ad esempio gli aggettivi associati a questi oggetti e argomenti. I punteggi di confidenza per ogni frase chiave che indicano la fiducia sul KP sono inclusi. I punteggi di affidabilità sono un valore compreso tra 0 e 1.
