生成式人工智能客户服务聊天机器人

这是通过 Google Cloud 的 Vertex AI PaLM API 使用生成式 AI 的客户服务聊天机器人演示。该应用程序还利用 MongoDB Atlas Search 在 MongoDB Atlas 数据库中查找相关答案。最后，该应用程序可以通过情绪分析来检测不满意的客户。

快速入门

MongoDB Atlas 设置

在您的 Atlas 帐户中部署新的 MongoDB 数据库集群。您可以使用免费的 M0 层来进行此演示。
创建XYZ-Corp数据库。

在XYZ-Corp数据库中创建Customer集合并插入以下文档。

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

在XYZ-Corp数据库中创建Insurance集合并插入以下文档。

{
  "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数据库中创建Claims集合并插入以下文档。

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

使用默认设置在Claims集合上创建名称为default Atlas Search 索引。请遵循 Atlas 搜索文档：https://www.mongodb.com/docs/atlas/atlas-search/create-index/。

聊天搜索集合中有一个小型知识库。将以下文档插入 MongoDB。在现实生活场景中，存储文本嵌入的不是文本向量，而是基于向量执行搜索。

  { "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.
