    Amazon Lex: Chatbot Building Service

    • Amazon Lex is a service for quickly building chatbots using voice or text input.
    • Chatbots can be used like hotel booking, ordering pizza, or for customer support.
    • Amazon Lex creates conversational AI that supports multiple languages.
    • Lex integrates with AWS Lambda, Amazon Connect, Amazon Comprehend, or Amazon Kendra.
    • It works by understanding user intent and invoking the correct Lambda function.
    • For example, if a user requests a hotel booking, Lex will recognize the intent to book a hotel.
    • When all necessary information is collected, the associated Lambda function is executed for the booking.
    • After successful booking, Lex responds to the user ("Thank you, your reservation went through successfully").
    • Users can interact with backend systems via text or voice.
    • If specific input parameters (like city, check-in date) are needed, the chatbot will dynamically gather input data called "Slots" from the user.
    • The chatbot dynamically gathers required information, thus invoking the correct Lambda function for fulfilling the user's intent.
    • Amazon Lex is a powerful chatbot creation service.
