TL;DR: In this article, a system for coordinating multiple chatbots in a group conversation using natural dialog systems is presented, including a creation unit that enables a user to create a group chat with chatbots, a response unit that allows the user to reply to any utterance extracted from a message received from a member of the group chat, a transmission unit that sends messages to every member of a group group chat; a development unit that develops chatbots that understand natural language and interact in a chat group chat using natural dialogue; a network connection; a first database that stores a knowledge base extracted
