What is a chatbot?
A chatbot is an artificial intelligence (AI) program that can simulate a natural language conversation (or chat) with a user via messaging apps, blogs, mobile apps, or by phone.
One of the most advanced and promising expressions of interaction between humans and machines is also described as a chatbot. However, from a technical point of view, a chatbot reflects only the natural evolution of a Natural Language Processing (NLP) question answering device. One of the most popular examples of natural language processing used in the end-use applications of different businesses is to formulate answers to questions in natural language.
