Yes/No Intents (Beta)

Version badge

Note

The Yes/No Intents feature is in Beta. We encourage you to try this feature out and provide us with feedback.

The Yes/No Intents feature enables machine learning to determine yes and no confirmations similar to regular Intent matching. That allows a small set of example sentences to train a model capable of understanding various yes and no confirmation phrases, introducing a more fluent natural language experience.

In the previous Confirmation words feature, you have a limited range of yes, and no variations, and you have to customize this by manually adding a list of synonyms. With the Yes/No Intents feature, you have a preinstalled vocabulary with the opportunity to add new words, which helps a virtual agent recognize different variations of yes and no Intents.

Before using Yes/No Intents:

User: Hello! 
Virtual agent: Do you want to play the Star Wars quiz?
User: Certainly
Virtual agent: Not sure I understood this correctly. Try again.

After using Yes/No Intents:

User: Hello! 
Virtual agent: Do you want to play the Star Wars quiz?
User: Certainly
Virtual agent: Let's start!

Yes/No Intents feature is supported in the Question, Optional Question and Code Nodes.

To set up this feature, do the following:

  1. Select a proper locale or use a default one
  2. Choose whether you want to use local for specific or all Flows
  3. Test your Flow by using the Interaction Panel

Select a Locale

A separate Yes/No Intents model is trained for each locale configured for the project. Therefore, the Yes/No Intents training is configured separately for each locale. The Universal locale has preinstalled English example sentences.

To configure a locale, do the following:

  1. To see the project's configured locales, click Manage > Localization.
  2. Select a locale and click ellipsis, then Edit Yes/No Intents.
  3. In the Edit Yes/No Intents pane, you can configure Intents for the current locale:
    • Yes Intent — by default, the setting is toggled on. When the setting is toggled off, the Intent is excluded from the build.
    • No Intent — by default, the setting is toggled on. When the setting is toggled off, the Intent is excluded from the build.
    • Reject Intent — by default, the setting is toggled on. You need to add examples manually. When the setting is toggled off, the Intent is excluded from the build.
  4. Additionally, for Yes and No Intents, you can add rules.
  5. Click Save & Build to build a model. The Yes/No model is always built when you edit and save settings.

Use Yes/No Intents for Specific or All Flows

You can use the Yes/No Intents feature for:

Project-level settings

To use Yes/No Intents for all Flows, do the following:

  1. In the left-side menu, click Manage > Settings.
  2. On the Settings page, click NLU Settings.
  3. In the General Flow Logic section, select one of the following options from the Yes/No Logic list:
    • Confirmation Words — disables the Yes/No Intents feature. Confirmation words are used the same way as before the Yes/No Intents feature. The option is enabled by default.
    • Yes/No Intents with extended rules — evaluates the standard Confirmation words logic first. If the standard Confirmation Words logic fails to determine the input type, the Yes/No Intents model is evaluated.
    • Yes/No Intents — evaluates the Yes/No Intents logic for every user input. The standard Confirmation Words logic is only used as a fallback when no Yes, No, or Reject Intents from the Yes/No Intents model are triggered.
  4. If you selected Yes/No Intents – with extended rules or Yes/No Intents, configure Yes/No threshold. The confidence threshold slider sets the minimum score required for Yes/No Intents to trigger. A Yes, No, or Reject Intent will only be triggered if the Intent score is greater than or equal to this threshold. This value applies to Yes/No Intents models for all locales. You can change this value for a specific Flow.
  5. Click Save to apply settings and build a model. The Yes/No model is always built when you edit and save settings.

If you have set settings at the project level but want to change them for certain Flows, you should go to the Flow-level settings.

Flow-level settings

By default, all Flows inherit the Yes/No Logic and the Yes/No threshold settings from the project-level configuration. You can override these settings for a specific Flow.

To use Yes/No Intents for a specific Flow, do the following:

  1. Open the existing Flow.
  2. In the upper-right corner of the Flow Editor page, select Settings.
  3. On the Configuration tab, in General Flow Logic activate checkbox near the Yes/No Logic setting.
  4. From the Yes/No Logic list, select one of the following options:
    • Confirmation Words — disables the current Flow's Yes/No Intents feature. Confirmation words are used the same way as before the Yes/No Intents feature. The option is enabled by default.
    • Yes/No Intents with extended rules — evaluates the standard Confirmation Words logic first. If the standard Confirmation Words logic fails to determine the input type, the Yes/No Intents model is evaluated.
    • Yes/No Intents — evaluates the Yes/No Intents logic for every user input. The standard Confirmation Words logic is only used as a fallback when no Yes, No, or Reject Intents from the Yes/No Intents model are triggered.
  5. If you selected Yes/No Intents – with extended rules or Yes/No Intents, configure Yes/No threshold. The confidence threshold slider sets the minimum score required for Yes/No Intents to trigger. A Yes, No, or Reject Intent will only be triggered if the Intent score is greater than or equal to this threshold. This value applies to Yes/No Intents models for all locales in the current Flow.
  6. Click Save to apply settings and build a model. The Yes/No model is always built when you edit and save settings.

Test your Flow by using the Interaction Panel

Tip

Starting from Cognigy 4.47, Yes/No Intents are supported in Expert mode.

Check if the Yes/No Intent feature works as expected via the Interaction Panel:

  1. In the existing Flow, open the Interaction Panel by clicking interaction-panel Chat with your Agent in the upper-right corner of the page.
  2. Run a Flow.
  3. On the INFO tab, select Input to view JSON. In the yesNoIntentResults object, you will see the result of Yes/No Intents model evaluation. Below are examples of possible results:

Depending on the Yes/No Logic setting, the Yes/No Intents model may not be evaluated. In that case, the yesNoIntentResults has the default values:

"yesNoIntentResults": {
  "finalIntentName": null,
  "finalIntentScore": null,
  "scores": []
}
Yes/No Intents are evaluated independently of regular Intents and do not overwrite the existing fields for Intents in the input object. Evaluation of Yes/No Intents only affects the type and yesNoIntentResults.

FAQ

Q1: What happens if the Yes/No Logic is set to Yes/No Intents, but both the Yes and No Intents have been individually disabled in the locale settings?

A1: The standard Confirmation Words logic is used.

Q2: I don’t see Yes/No Intents in the Intent Trainer. Why?

A2: Yes/No Intents support has not been implemented in the Intent Trainer.

Q3: I don’t see the traffic lights and training feedback when I train Yes/No Intents. Why?

A3: The traffic light system has not yet been implemented for Yes/No Intents.

Q4: Are Yes/No Intents independent of standard intent scoring?

A4: Yes, the Yes/No Intents are completely independent of standard intent scoring (input.intentScore or input.nlu.intentMapperResults). They specifically find the types nAnswer and yAnswer within the Flow. These types are used for the Yes/No type in Question Nodes and for confirming intents, similar to confirmation words.

Q5: How are Yes/No Intents evaluated when the Execute Flow node is used with and without the Parse Intents toggled on?

A5: Yes/No Intent scoring behavior differs only if the Yes/No Intent settings are different in the two Flows.

For example:

Prerequisites:

  • Flow A has Yes/No Intents and only one node, which is an Execute Flow node that executes Flow B.
  • Flow B has Yes/No Intents - with extended rules and one Say node.

Scenario 1:

  1. The Parse Intents setting is disabled in the Execute Flow node of Flow A.
  2. When the user sends yes in Flow A, Yes Intent is triggered in Flow B.
  3. Flow B inherits the Yes/No Logic from Flow A.

Scenario 2:

  1. The Parse Intents setting is enabled in the Execute Flow node of Flow A.
  2. When the user sends yes in Flow A, Yes Intent is not triggered in Flow B.
  3. Flow B uses its own Yes/No Logic.
