AMAZON.QnAIntent
Note
Before you can take advantage of the generative AI features, you must fulfill the following prerequisites
-
Navigate to the Amazon Bedrock console
and sign up for access to the Anthropic Claude model you intend to use (for more information, see Model access). For information about pricing for using Amazon Bedrock, see Amazon Bedrock pricing . -
Turn on the generative AI capabilities for your bot locale. To do so, follow the steps at Optimize Lex V2 bot creation and performance by using generative AI.
You can take advantage of Amazon Bedrock FMs to help answer customer questions in a bot conversation. Amazon Lex V2 offers a built-in AMAZON.QnAIntent that you can add to your bot. This intent harnesses generative AI capabilities from Amazon Bedrock by recognizing customer questions and searching for an answer from the following knowledge stores (for example, Can you provide me details on the baggage limits for my international flight?). This feature reduces the need to configure questions and answers using task-oriented dialogue within Amazon Lex V2 intents. This intent also recognizes follow-up questions (for example, What about domestic flight?) based on the conversation history and provides the answer accordingly.
Ensure that your IAM role has the proper permissions to access the AMAZON.QnAIntent by following the steps at Permissions for the AMAZON.QnAIntent.
To take advantage of the AMAZON.QnAIntent you must have set up one of the following knowledge stores.
-
Amazon OpenSearch Service database – For more information, see Creating and managing Amazon OpenSearch Service domains.
