Extração de Frase-chave

A extração de palavras-chave é o processo automatizado de extração das palavras com mais relevância e expressões do texto de entrada. Ela ajuda a resumir o conteúdo e reconhece os principais tópicos.

O modelo de extração de frases-chave usa o NLP e o ML para encontrar insights relacionados aos pontos principais do texto. Ele entende o texto de entrada não estruturado e retorna palavras-chave e frases-chave (KPs).

As KPs consistem em assuntos e objetos que estão sendo falados no documento. Quaisquer modificadores, como adjetivos associados a esses sujeitos e objetos, também são incluídos na saída. Pontuações de confiança para cada frase-chave que significam a confiança sobre o KP são incluídas. As pontuações de confiança são um valor de 0 a 1.
