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
{ "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 or proactive 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 The search history of the same session can impact the search result. You can use the conversation ID below for the 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
{ "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, } ] } } }

- 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
For the steps to send feedback, go to Send feedback to Agent Assist.
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 isstruct
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"
}
