生成 AI カスタマーサービスチャットボット

これは、Google Cloud の Vertex AI PaLM API を通じて Generative AI を使用したカスタマーサービスチャットボットのデモです。また、このアプリは MongoDB Atlas Search を利用して、MongoDB Atlas データベース内で関連する回答を探します。最後に、アプリは感情分析により不満を抱いている顧客を検出できます。

MongoDB Atlas のセットアップ

新しい MongoDB データベースクラスターを Atlas アカウントにデプロイします。このデモには無料の M0 層を使用できます。
XYZ-Corpデータベースを作成します。
XYZ-CorpデータベースにCustomerコレクションを作成し、次のドキュメントを挿入します。
```
{
  "customer_id" : " 111 " ,
  "conversation" :[],
  "Name" : " Venkatesh Shanbhag "
} 
```

XYZ-CorpデータベースにInsuranceコレクションを作成し、次のドキュメントを挿入します。

{
  "context" : " You are a Customer support agent with name Sara working for XYZ-corp. n It does provides property Insurance.

XYZ-CorpデータベースにClaimsコレクションを作成し、次のドキュメントを挿入します。

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

デフォルト設定を使用して、 Claimsコレクションにdefaultという名前の Atlas Search インデックスを作成します。 Atlas Search ドキュメントに従ってください: https://www.mongodb.com/docs/atlas/atlas-search/create-index/。

小規模な知識ベースがチャット検索コレクションで利用できます。以下のドキュメントをMongoDBに挿入します。実際のシーンでは、テキストの代わりにテキスト埋め込みのベクトルが保存され、ベクトルに基づいて検索が実行されます。

  { "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.
