Artificial Intelligence (AI) increasingly integrates human daily lives with the creation and analysis of intelligent software and hardware, called intelligent agents.

A chatbot is a typical example of an AI system and one of the most elementary and widespread examples of intelligent Human-Computer Interaction. Developments in AI enhance the abilities of chatbots to mimic human agents in conversation.

A chatbot is an artificial intelligence program and a Human– computer Interaction (HCI) model. It responds like a smart entity when conversed with through text or voice and understands one or more human languages by Natural Language Processing (NLP).

This technology started in the 1960’s; the aim was to see if chatbot systems could fool users that they were real humans.

The purpose of a chatbot system is to simulate a human conversation; the chatbot architecture integrates a language model and computational algorithms to emulate informal chat communication between a human user and a computer using natural language.

Chatbots can mimic human conversation and entertain users but they are not built only for this. They are useful in applications such as education, information retrieval, business, and e-commerce. They became so popular because there are many advantages of chatbots for users and developers too.

In business, chatbots have become so common because they reduce service costs and can handle many customers simultaneously. Chatbots are more friendly and attractive to users than, for example, the static content search in frequently asked questions (FAQs) lists.

Chatbots may serve a number of purposes, such as customer service, social and emotional support, information, entertainment, and tiesthe user to other people or machines.
