When the intent 'who are you' is recognised, the bot will introduce himself and ask if the user would like to order a ticket.

​

In a totally different part of the conversation, at the end of the Book train ticket conversation flow, the chatbot asks for a booking confirmation.

Both bot questions expect a user intent answer of yes or no. To support correct reuse of intents, we can define a bot dialog intent linked to a certain context. The user will only be redirected to the linked bot dialog if the intent is recognized and the user is in a specific context.

• Add the yes and no intents and train them with expressions

• In the bot dialog Confirm booking go to the NLP tab

• Add an output context confirm_booking. Press enter to create the output context

• When a user reaches this bot dialog the output context is added to the user session context

• Add the Confirmed Booking bot dialog with required context confirm_booking and intent yes in the NLP tab. When the yes intent is returned by the NLP model and the user has the context confirm_booking, he will be redirected to this bot dialog.

• Add the Cancel booking bot dialog with the required context confirm_booking and intent no

• Add output context who_are_you in the bot dialog Who are you

• Add the Yes book ticket bot dialog with required context who_are_you and intent yes

• Add the No book ticket bot dialog with required context who_are_you and intent no

Testing the flow in the emulator

• Click on the Emulator tab to test your dialog flow. Ask your bot who they are:

• Go to the debug mode and select the first message in the messages list who are you to view the received information after sending this user message.

• The context who_are_you has been added to the user session with an initial lifespan value of 1 as you can see in the context section

• The user is redirected to the bot dialog

• The NLP result section shows that the 'who are you' intent has been recognised as top scoring intent

• In the Message Data section, we see the message being sent by the bot as answer

• In the User Session section, we see the context list of the user with name and lifespan

The next tutorial will show you how to redirect the user to a specific bot dialog, depending on the conditions of the values in session variables.
