Explanation

In Amazon Lex, an Intent is the component that identifies what the user wants to do or accomplish. It represents the purpose or goal behind a user's input.

Key points about Intents:

• Intents define the action the user wants to perform (e.g., 'book an appointment', 'check order status', 'make a reservation')

• Each intent contains:

  • Utterances: Sample phrases users might say to invoke the intent

  • Slots: Required information to fulfill the intent (e.g., date, time, location)

  • Fulfillment: The action taken when the intent is complete

Other components explained:

• Slots: These are the specific pieces of information needed to fulfill an intent (like parameters)

• Utterances: These are sample phrases or expressions users might say to trigger an intent

• Fulfillment: This is the action taken when all required information (slots) is collected

Example:

For a 'BookAppointment' intent:

• Intent: Book an appointment

• Utterances: 'I want to book an appointment', 'Schedule a meeting', 'Make an appointment'

• Slots: Date, Time, ServiceType, DoctorName

• Fulfillment: Call Lambda function to create appointment in database

Therefore, the component that identifies what the user wants to do is the Intent.
