Generative knowledge assist

Generative knowledge assist provides answers to your agent's questions based on information in documents you provide. You can specify your domain name or upload documents for a data store agent to index. Generative knowledge assist synthesizes that information with the ongoing conversation and available customer metadata to give a more relevant and timely answer to your agent.

Proactive generative knowledge assist follows the ongoing conversation between your agent and the customer. It proactively provides search query suggestions based on the current conversation context and the answer.

Create a data store agent

Unless you're the project owner, you need these roles to create a data store agent:
- Dialogflow API Admin
- Discovery Engine Admin
Activate the Vertex AI Agent Builder API in the Vertex AI console.
To create the agent, follow the steps in Data store agents.

Answer questions from your human agents

The data store agent can answer the questions from your human agents based on the documents you provided.

Step 1: Create a conversation profile

Create a conversation profile using the Agent Assist console or the API.

Create from console

You must enable the generative knowledge assist suggestion type and link it to the data store agent from the previous step.
Optional: Use the Disable agent search query logging checkbox to indicate whether you would like Google to collect and store redacted search queries for potential quality improvement.
You can use the Enable conversation augmented query checkbox to indicate whether you would like to take the conversation context between the human agent and the user into consideration when generating the answer for the search query.

Create from API

The following steps illustrate how to create a ConversationProfile with a HumanAgentAssistantConfig object. You can also perform these actions using the Agent Assist console.

To create a conversation profile, call the create method on the ConversationProfile resource.

Before using any of the request data, make the following replacements:

PROJECT_ID: your project ID
LOCATION_ID: the ID for your location
AGENT_ID: your data store agent ID from the previous step

The following is a JSON example:

  {
    "displayName": "my-conversation-profile-display-name",
    "humanAgentAssistantConfig": {
      "humanAgentSuggestionConfig": {
        "featureConfigs": [
          {
            "suggestionFeature": {
              "type": "KNOWLEDGE_SEARCH"
            },
            "queryConfig": {
              "dialogflowQuerySource": {
                "humanAgentSideConfig": {
                  "agent": "projects/PROJECT_ID/locations/LOCATION_ID/agents/AGENT_ID"
                }
              }
            },
            "disableAgentQueryLogging": false,
            "enableConversationAugmentedQuery": false,
          }
        ]
      }
    }
  }

When you create a conversation profile in the Agent Assist console, Agent Assist automatically enables both generative knowledge assist and proactive generative knowledge assist. To disable proactive generative knowledge assist, you must create your conversation profile using the API.

Step 2: Use a data store agent

Optionally, use the SearchKnowledge API to get the answers from the data store agent. You can also use the following configurations as part of your SearchKnowledge request:

querySource: Set this field to indicate whether an agent typed the query orproactive generative knowledge assist automatically suggested it.
exactSearch: Set this field to indicate whether to search the exact input query without query rewrite.
endUserMetadata: Set this field to include additional information about the end user that improves the generated answer. For more details, see the Data Store agent performance personalization page.
searchConfig: Set this field for additional control to boost and filter knowledge documents. For more details, see the Data Store agent performance search configuration page.

Before using any of the request data, make the following replacements:

PROJECT_ID: your project ID
LOCATION_ID: the ID for your location
CONVERSATION_PROFILE_ID: your conversation profile ID from the previous step
SESSION_ID: your search session ID
CONVERSATION_ID: the conversation (between human agent and end user) where the search request is triggered
MESSAGE_ID: the latest conversation message when the search request is triggered

Here is an example JSON request:

{
  "parent": "projects/PROJECT_ID/locations/LOCATION_ID"
  "query": {
    "text": "What is the return policy?"
  }
  "conversationProfile": "projects/PROJECT_ID/locations/LOCATION_ID/conversationProfiles/CONVERSATION_PROFILE_ID"
  "sessionId": "SESSION_ID
  "conversation": "projects/PROJECT_ID/locations/LOCATION_ID/conversations/CONVERSATION_ID"
  "latestMessage": "projects/PROJECT_ID/locations/LOCATION_ID/conversations/CONVERSATION_ID/messages/MESSAGE_ID
  "querySource": AGENT_QUERY
  "exactSearch": false
  "searchConfig": {
    "filterSpecs": {
      "filter": "category: ANY(\"persona_B\")"
    }
  }
  "endUserMetadata": {
    "deviceOwned": "Google Pixel 7"
  }
}

Optionally, provide conversation and latest_message resource names if the agent's search happens during a conversation with a user. These two fields are required if you enable the enable_conversation_augmented_query option and prefer enhancing the query answer experience with the conversational context between your agent and the user.

Simulator

Test your data store agent in the Agent Assist simulator.

In the preceding example, the data store agent answers the user query What is the refund processing time? with the following information:

Gen AI generated answer: When the package with your return arrives at the seller's return center, it may take up to 7 additional business days to process. Check the status of your refund with the return tracking number found on your orders page.
The title of the relevant knowledge document: Returns & refunds.

Proactively suggest Q & A for your agents

Proactive generative knowledge assist follows an ongoing conversation and proactively provides search query suggestions and answers.

Step 1: Create a conversation profile

Create a conversation profile using the Agent Assist console or the API. We recommend that you create a conversation profile using the Agent Assist console.

Create from console

Enable the Generative knowledge assist suggestion type and link it to the data store agent from the previous step. This enables the data store agent to proactively provide query and answer suggestions and answer manual search queries from your human agents.
Optional: Use the Show all suggested queries for conversation checkbox to have the data store agent show all these queries, even when there is not an answer found from your knowledge documents. This is intended for testing which queries can be pulled from the ongoing conversation.
Optional: Use the Load proactive answers asynchronously checkbox to only get query suggestions. You can manually submit the suggested query to the SearchKnowledge API and automatically submit in the Agent Assist console simulator and UI modules.

Create from API

The following steps create a ConversationProfile with a HumanAgentAssistantConfig object. You can also perform these actions using the Agent Assist console.

To create a conversation profile, call the create method on the ConversationProfile resource.

Before using any of the request data, make the following replacements:

PROJECT_ID: your project ID
LOCATION_ID: the ID for your location
AGENT_ID: your data store agent ID from the previous step

The following is a JSON example:

  {
    "displayName": "my-conversation-profile-display-name",
    "humanAgentAssistantConfig": {
      "humanAgentSuggestionConfig": {
        "featureConfigs": [
          {
            "suggestionFeature": {
              "type": "KNOWLEDGE_ASSIST"
            },
            "queryConfig": {
              "dialogflowQuerySource": {
                "agent": "projects/PROJECT_ID/locations/LOCATION_ID/agents/AGENT_ID"
              }
            },
            "enableQuerySuggestionWhenNoAnswer": false,
          }
        ]
      }
    }
  }

Step 2: Handle conversations at runtime

Proactive generative knowledge assist processes conversations at runtime to proactively provide search query suggestions based on the current conversation context and the answer.

Create a conversation

First, you must create a conversation:

REST

To create a conversation, call the create method on the Conversation resource.

Before using any of the request data, make the following replacements:

PROJECT_ID: your Cloud project ID
LOCATION_ID: your location ID
CONVERSATION_PROFILE_ID: the ID you received when creating the conversation profile

HTTP method and URL:

POST https://dialogflow.googleapis.com/v2/projects/PROJECT_ID/locations/LOCATION_ID/conversations

Request JSON body:

{
  "conversationProfile": "projects/PROJECT_ID/locations/LOCATION_ID/conversationProfiles/CONVERSATION_PROFILE_ID",
}

To send your request, expand one of these options:

curl (Linux, macOS, or Cloud Shell)

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login , or by using Cloud Shell, which automatically logs you into the gcloud CLI . You can check the currently active account by running gcloud auth list.

Save the request body in a file named request.json, and execute the following command:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "x-goog-user-project: PROJECT_ID" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://dialogflow.googleapis.com/v2/projects/PROJECT_ID/locations/LOCATION_ID/conversations"

PowerShell (Windows)

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login . You can check the currently active account by running gcloud auth list.

Save the request body in a file named request.json, and execute the following command:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred"; "x-goog-user-project" = "PROJECT_ID" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://dialogflow.googleapis.com/v2/projects/PROJECT_ID/locations/LOCATION_ID/conversations" | Select-Object -Expand Content

You should receive a JSON response similar to the following:

{
  "name": "projects/PROJECT_ID/locations/LOCATION_ID/conversations/CONVERSATION_ID",
  "lifecycleState": "IN_PROGRESS",
  "conversationProfile": "projects/PROJECT_ID/locations/LOCATION_ID/conversationProfiles/CONVERSATION_PROFILE_ID",

Complete the conversation

When the conversation ends, use the API to complete the conversation.

REST

To complete the conversation, call the complete method on the conversations resource.

Before using any of the request data, make the following replacements:

PROJECT_ID: your GCP project ID
CONVERSATION_ID: the ID you received when creating the conversation

HTTP method and URL:

POST https://dialogflow.googleapis.com/v2/projects/PROJECT_ID/conversations/CONVERSATION_ID:complete

To send your request, expand one of these options:

curl (Linux, macOS, or Cloud Shell)

Execute the following command:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "x-goog-user-project: PROJECT_ID" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d "" \
     "https://dialogflow.googleapis.com/v2/projects/PROJECT_ID/conversations/CONVERSATION_ID:complete"

PowerShell (Windows)

Execute the following command:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred"; "x-goog-user-project" = "PROJECT_ID" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -Uri "https://dialogflow.googleapis.com/v2/projects/PROJECT_ID/conversations/CONVERSATION_ID:complete" | Select-Object -Expand Content

You should receive a JSON response similar to the following:

{
  "name": "projects/PROJECT_ID/conversations/CONVERSATION_ID",
  "lifecycleState": "COMPLETED",
  "conversationProfile": "projects/PROJECT_ID/conversationProfiles/CONVERSATION_PROFILE_ID",
  "startTime": "2018-11-05T21:05:45.622Z",
  "endTime": "2018-11-06T03:50:26.930Z"
}

def complete_conversation(project_id, conversation_id):
    """Completes the specified conversation. Finished conversations are purged from the database after 30 days.

    Args:
        project_id: The GCP project linked with the conversation.
        conversation_id: Id of the conversation."""

    client = dialogflow.ConversationsClient()
    conversation_path = client.conversation_path(project_id, conversation_id)
    conversation = client.complete_conversation(name=conversation_path)
    print("Completed Conversation.")
    print("Life Cycle State: {}".format(conversation.lifecycle_state))
    print("Conversation Profile Name: {}".format(conversation.conversation_profile))
    print("Name: {}".format(conversation.name))
    return conversation

Simulator

You can test your data store agent in the Agent Assist simulator.

In the preceding example, the data store agent provides the following suggestions:

Suggested query: Refund processing time.
Gen AI generated answer: After your return is processed, you receive your refund in 7 days. The refund amount should be for the full value of the items returned, but doesn't include shipping & service fees.
The title of the relevant knowledge document: Returns & refunds - Help.

Step 3: Pub/Sub suggestion notifications

You can set the notificationConfig field when creating a conversation profile to receive notifications for suggestions. This option uses Pub/Sub to send suggestion notifications to your application as the conversation proceeds and new suggestions become available.

If you're integrating through the AnalyzeContent API, you have the option to enable the disable_high_latency_features_sync_delivery config in ConversationProfile to ensure that the AnalyzeContent API will respond, without waiting for the proactive generative knowledge assist suggestions, and deliver the suggestions through Pub/Sub.

You can also enable this configuration from the Agent Assist console.

Send feedback

Use the answer record to call the UpdateAnswerRecord method to send AnswerFeedback to indicate possible feedback events:

displayed: Whether the suggestion is displayed to the human agent.
clicked: Whether the suggestion is clicked by the human agent.
correctness_level: Whether the suggestion is correct or not. A typical use case is to provide thumbs up and thumbs down buttons for the human agent to provide feedback.
answer_copied: Whether the answer is copied by the human agent.
clicked_uris: The URIs clicked by the human agent.

For more details, go to Send feedback to Agent Assist.

Generative knowledge assist can either answer agent questions or proactively suggest question and answer pairs. These two features require different JSON requests for sending feedback.

Answer agent questions

The following is an example JSON request for sending feedback about answering agent questions.

{
  "name": "projects/PROJECT_ID/locations/LOCATION_ID/answerRecords/ANSWER_RECORD_ID",
  "answerFeedback": {
    "displayed": true
    "clicked": true
    "correctnessLevel": "FULLY_CORRECT"
    "agentAssistantDetailFeedback": {
      "knowledgeSearchFeedback": {
        "answerCopied": true
        "clickedUris": [
          "url_1",
          "url_2",
          "url_3",
        ]
      }
    }
  }
}

Proactively suggest Q&A

The following is an example JSON request for sending feedback about proactive suggestions.

{
  "name": "projects/PROJECT_ID/locations/LOCATION_ID/answerRecords/ANSWER_RECORD_ID",
  "answerFeedback": {
    "displayed": true
    "clicked": true
    "correctnessLevel": "FULLY_CORRECT"
    "agentAssistantDetailFeedback": {
      "knowledgeAssistFeedback": {
        "answerCopied": true
        "clickedUris": [
          "url_1",
          "url_2",
          "url_3",
        ]
      }
    }
  }
}

Metadata

If you configure metadata for a knowledge document, both generative knowledge assist and proactive generative knowledge assist will return the document's metadata along with the response.

For example, you can use metadata to mark whether the knowledge document is your internal private article or an external public article. Within both the Agent Assist simulator and UI modules, both generative knowledge assist and proactive generative knowledge assist automatically display a document metadata value for certain keys.

gka_source_label: Value is displayed in the suggestion card directly.
gka_source_tooltip: When the value is struct type, holding your cursor over the source link expands and displays the value in a tooltip.

If you have the following metadata for a knowledge document, then the suggestion card lists the source as External Doc and the tooltip adds doc_visibility: public doc.

Metadata: None { "title": "Public Sample Doc", "gka_source_label": "External Doc", "gka_source_tooltip": { "doc_visibility": "public doc" } }
