Chatbot de atendimento ao cliente com IA generativa

Esta é uma demonstração de um chatbot de atendimento ao cliente usando IA generativa por meio das APIs Vertex AI PaLM do Google Cloud. O aplicativo também aproveita o MongoDB Atlas Search para procurar respostas relevantes em um banco de dados MongoDB Atlas. Finalmente, o aplicativo pode detectar clientes insatisfeitos com análise de sentimento.

  { "question" : " Proof of income " , "Answer" : " This document may become necessary whenever the sum n proposed is very high. Normally a sum proposed which is seven n to eight times of the declared income is acceptable for n insurance.
