nluIntentConfidenceThreshold

var nluIntentConfidenceThreshold: Double?

Determines the threshold where Amazon Lex will insert the AMAZON.FallbackIntent, AMAZON.KendraSearchIntent, or both when returning alternative intents in a PostContent or PostText response. AMAZON.FallbackIntent and AMAZON.KendraSearchIntent are only inserted if they are configured for the bot.

You must set the enableModelImprovements parameter to true to use confidence scores in the following regions.

  • US East (N. Virginia) (us-east-1)

  • US West (Oregon) (us-west-2)

  • Asia Pacific (Sydney) (ap-southeast-2)

  • EU (Ireland) (eu-west-1)

In other Regions, the enableModelImprovements parameter is set to true by default.

For example, suppose a bot is configured with the confidence threshold of 0.80 and the AMAZON.FallbackIntent. Amazon Lex returns three alternative intents with the following confidence scores: IntentA (0.70), IntentB (0.60), IntentC (0.50). The response from the PostText operation would be:

  • AMAZON.FallbackIntent

  • IntentA

  • IntentB

  • IntentC
