In modern usage, a chatbot refers to a computer program designed to simulate conversation with human users using natural language processing.
The word "chatbot" is a portmanteau, combining the words "chat" and "robot".
The term "chat" originated from the word "chatter", which can be traced back to Old English and Middle English. It originally referred to casual and informal conversation.
"Robot" comes from the Czech word "robota", which means slave or forced labor. This term was introduced into English by playwright Karel Čapek in his play "R.U.R". (Rossum's Universal Robots) in 1920. It referred to humanoid machines programmed to perform various tasks.
The combination of "chat" and "robot" to form "chatbot" reflects an automated program designed to simulate conversation or chat with users. The word has since become widely used to describe various artificial intelligence programs that can engage in conversations with humans.
