Working with the Confirmation Nodes

Confirmation Node allows you to prompt the user for a yes or no answer. It helps in the verification or allowing users to accept or decline a choice.

For example, in the Books Flight Bot, you can use a confirmation node to prompt the user to respond if they would like to know the weather forecast of the destination.

Confirmation node’s conditional transitions go beyond the If-Else If-Else expressions. The transition depends on user reply: assertion (yes) or negation (no). The Else condition comes into play if their answer isn’t both.

Set up a Confirmation Node

Setting up a confirmation node in a dialog task involves the following steps.

Add a Confirmation Node to the Dialog Task

To add a confirmation node to the dialog task, follow the below steps:

  1. Open the Dialog Task in which you want to add the Confirmation node.
  2. Click the diydialogtaskplusicon icon next to the respective node.
  3. Select Confirmation > New confirmation node. You can also select an existing Confirmation node from the list.
  4. The Confirmation window is displayed with the Component Properties tab selected by default.

Configure the Component Properties

Note: The configurations you set up or edit in these sections reflect in all other dialog tasks that use this node.

To configure the component properties, follow the below steps:

  1. On the Component Properties tab, under the General Settings section, enter a Name and a Display Name.
  2. Under the User Prompts section, you can compose the confirmation request either as plain text or as a JavaScript message.
  3. Click Manage Prompt Messages.
  4. On the Prompt Messages page, you can perform any of the below actions:
    • To edit the default sample message by adding context object variables or javascript code, click the sample message.
    • To add a new prompt message, click Add Prompt Message.
      1. On the Message editor, in the Channel drop-down list, All Channels is the default value. To create a channel-specific message, select the channel from the list.
      2. On the Message editor, the Plain Text tab is the default selection. If you want to compose a Javascript message, click the JavaScript tab.
        Note: You can use any value that is currently stored in the context. For example, print('Hello'+ context.session.UserContext.firstName+ '. How can I help you')

      3. Compose the message and click Save.
      4. To add more bot responses, repeat the above steps.
  5. You can add context-specific Synonyms for Yes and No within the Confirmation node to suit the dialog’s context.
    Post v8.1, the platform can identify the emojis in user utterance and consider them for confirmation/rejection, for example, a thumbs-up emoji will be taken to mean confirmation from the user.
  6. In the Variable Namespaces section (v8.0), associate the variable namespaces to execute this node and its transitions. This option is visible only when the Variable Namespace is enabled for the bot. You can go with the task level settings or customize it for this node. For more information, refer to Managing Namespace.

Configure the Instance Properties

  1. On the Confirmation window, click the Instance Properties tab.
  2. Under the Interruptions Behavior section, you can configure the interruptions behavior for this node.
    Note: The settings in the Instance Properties tab are specific to the current task and do not reflect in other dialog tasks that use this entity node.

    • Use the task level ‘Interruptions Behavior’ setting: The bot refers to the Interruptions Behavior settings set at the dialog task level.
    • Customize for this node option: You can customize the Interruptions Behavior settings for this node by selecting this option and configuring the same. Refer to Interruption Handling and Context Switching article for more information.
  3. Under the Precedence section, when the user’s input for an entity consists of a valid value for the entity and another intent, you can control the experience by choosing between Intent over Entity or Entity over Intent options. For example, if a Flight Booking bot prompts for the destination and the user enters, Bangalore, how’s the weather there? you can define how the bot responds in such cases; pick the entity and add the intent to the follow-up intents stack or go ahead with the intent first based upon the Interruptions Behavior settings.
  4. Under the Custom Tags section, add tags to build custom profiles of your bot conversations. Click here for more.

Configure the Connections (or Transitions) Properties

Confirmation node’s conditional transitions go beyond the If-Else If-Else expressions used for the other nodes. You can define conditional expression based on a context object value, else a user assertion (yes), or else user negation (no). Beyond the three, you can define a fallback Else condition to trigger.

To setup component transitions, follow the below steps:

  1. On the Confirmation window, click the Connections tab.
  2. On the Connections tab, under the Connection Rules section, Context is selected by default.
  3. Under If, you can enter the following:
    • If condition: Enter a context object to compare.
    • Operator: In the drop-down list, select one of these operators: Exists, equals to, greater than equals to, less than equals to, not equal to, greater than, and less than.
    • Value: Enter the value with which to compare the context object. For example,  Context.entity.PassengerCount (Context object) greater than (operator) 5 (specified value).
    • In the Then go to drop-down list, select the node to execute if this condition succeeds.
  4. Under Else IF user response is affirmative (For example, Yes) section, in the Then go to drop-down list and select the node to execute next if the user’s response is affirmative.
  5. Under Else IF user response is negative (For example, No) section, in the Then go to drop-down list and select the node to execute next if the user’s response is affirmative.
Note: If you do not want to write an IF Context, hover over the section and click the icon on the top-right.
Note: When you set up an IF Context conditional expression as explained in step 3, the conditions in steps 4 and 5 come into play only if the IF Context expression does not hold true. If you want to add other conditions, click Add Else If to write them.

Platform detection of Yes/No is based on the below keywords.

Improvements made to the NL engine in v8.0 of the platform ensures that the yes/no synonyms, including the internal ones, are processed at the same time and the earliest choice is taken. This means that something like of course not is considered as NO, earlier it was mapping to YES because of of course being part of the YES synonym.
Also, the yes/no synonyms are concepts and patterns as well.

For yes:
'kay, <I agree, <I am>, <I am certain>, <I am listening>, <I am pleased to>, <I am sure>, <I can believe it>, <I can believe that>, <I can see that>, <I can try>, <I consent, <I could not agree with you more, <I did>, <I do>, <I give consent, <I give my consent, <I guess so, <I have no objection, <I think so, <I totally agree, <I understand>, <I will drink to that, <O.K., <OK, <a'ight, <a'right, <absolutely, <accept>, <accepted>, <ack, <affirmative>, <agreed, <ah yes, <all right, <alright, <always>, <apparently>, <approved, <ay, <aye, <be my guest, <beyond a doubt>, <bring it on>, <but of course, <by all means, <can not argue with that, <certainly>, <completely, <confirmed, <constantly>, <continue, <correct>, <could be>, <could not have said it better, <da, <damn good, <damn straight, <definitely, <delighted, <do it>, <especially, <evidently>, <exactly, <extremely>, <fantastic>, <fine>, <for sure, <fortune smiles on that, <fully, <generally, <go ahead>, <go ahead with, <he does>, <he is>, <hell yeah, <highly likely>, <how true>, <i guess>, <in this case>, <indeed, <indefinitely, <indubitably>, <it does>, <it is>, <it is highly likely>, <it will be a pleasure to, <it will be my pleasure to, <it would be a pleasure, <let us try>, <make it so>, <makes sense, <most assuredly, <most certainly, <mostly>, <my pleasure>, <naturally>, <no doubt, <no objections>, <no problem>, <nod, <nods, <o.k., <of course, <oh alright, <oh okay, <oh sure, <ok, <okey dokey, <one hundred percent, <only just>, <perfect>, <please do>, <positively, <precisely, <probably>, <right>, <right ,, <right brah, <right on, <righto, <righty-ho, <she does>, <she is>, <shure, <si, <so will you, <sounds wonderful, <supposedly, <sure, <sure thing, <surely, <that is alright, <that is correct, <that is good, <that is right, <thats great , yes, <thats great yes, <they are>, <they do>, <thumbs up, <totally, <true>, <two thumbs up, <uh-huh, <undoubtedly, <unquestionably, <very well, <very well indeed, <we can try>, <we did>, <we do>, <we should try>, <well maybe you are right, <well perhaps you are right, <whatever>, <will do>, <with pleasure, <without a doubt, <wonderful>, <yah, <yay, <yea, <yeah, <yeah definitely, <yeah sure, <yeh, <yep, <yeppers, <yes, <yes please, <yes really, <yip, <you are right, <you bet>, <you could say that>, <you may, <you may be right, <you may have a point, <yup, <yuppers, I would say so, Y, d'accord, it_is_ok, its_ok, okay, okey, positive, right-o, touche, why_not, will_be_nice, ya, yes, yo, you_bet_you, ys

In both cases, <means the start of the sentence and> means the end of the sentence. So, many of these words are only treated as a yes or no if they appear at the start of an utterance, not in the middle.
