Building Chatbot Using Amazon Lex and Integrating with A Chat Application

Abstract

Engaging in hotel room reservations has remained a hassle even though there are few applications which provide their own services. This study aims at building a voice chatbot device that can be used for hotel reservation using Amazon Lex Service with Facebook Messenger as the communication platform. The chatbot is built by leveraging on Amazon Web Services (AWS) in the form of a service called Amazon Lex for configuring the bot with utterances and responses and Lambda Functions to validate the responses while carrying out the operations by using Facebook Messenger service. The lambda function runs a script that collects input in the form of plain text or by using voice recognition using the microphone connected to it, which is sent to the Amazon Lex to be processed using various services provided by Amazon Web Services. Then the chatbot sends back a suitable response to the user through the speaker connected to the device or in the form of plain text. This bot is also integrated with a Facebook page and can be implemented in the real-world applications as well. The admin of the page has access to entire messages that are received through the chatbot and can do the appropriate arrangements as required.
