生成式人工智慧客戶服務聊天機器人

這是透過 Google Cloud 的 Vertex AI PaLM API 使用生成式 AI 的客戶服務聊天機器人演示。該應用程式還利用 MongoDB Atlas Search 在 MongoDB Atlas 資料庫中尋找相關答案。最後，該應用程式可以透過情緒分析來檢測不滿意的客戶。

MongoDB Atlas 設定

在您的 Atlas 帳戶中部署新的 MongoDB 資料庫叢集。您可以使用免費的 M0 層來進行此演示。
建立XYZ-Corp資料庫。

在XYZ-Corp資料庫中建立Customer集合並插入以下文件。

{
  "customer_id" : " 111 " ,
  "conversation" :[],
  "Name" : " Venkatesh Shanbhag "
}

在XYZ-Corp資料庫中建立Insurance集並插入以下文件。

{
  "context" : " You are a Customer support agent with name Sara working for XYZ-corp. n It does provides property Insurance. Sara will not reply for any queries regarding other types of insurance. n The company covers insurance of properties like - Hospitals, offices, shops, apartments. n Max insurance covered will decline over period of time. n XYZ-Corp only covers Fire and Earthquake hazard insurance. n You are allowed to provide only the details regarding the company itself. n Do not repond with sentiment in any of the responses. " ,
  "type" : " Intro "
}

在XYZ-Corp資料庫中建立Claims集合並插入以下文件。

{
  "claim_number" : " 12345 " ,
  "Name" : " Venkatesh Shanbhag " ,
  "Claim_amount" :{ "$numberLong" : " 10000 " },
  "Currency" : " USD " ,
  "Claim_status" : " In progress " , "customer_id" : " 111 "
}

使用預設設定在Claims集合上建立名稱為default Atlas Search 索引。請遵循 Atlas 搜尋文件：https://www.mongodb.com/docs/atlas/atlas-search/create-index/。

聊天搜尋集合中有一個小型知識庫。將以下文件插入 MongoDB。在現實生活場景中，儲存文字嵌入的不是文字向量，而是基於向量執行搜尋。

  { "question" : " claim " , "Answer" : " Please provide 5 digit claim number " }
  { "question" : " Not resolved " , "Answer" : " Do you want to connect to an Agent for further assistence " }

  { "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. But proposals do come to the insurer when the n known source of income of the proposer is much less compared n to the amount of insurance desired. A service holder normally n does not face this problem as his sources of income are n verifiable. n In case of business people, the assessed income is at times n much less compared to what is a desirable income for the n amount of insurance desired. In such cases the insurer at n times calls for assessed income tax returns, or Chartered n Accountant’s certificate etc. Such precautions are necessary n to eliminate the possibility of moral hazard.
