Hunter's comment
Chatterbot is a computer program which is designed to simulates intellectual conversation with one human or more both audio or text. In the beginning, computer program (bots) this is tested through Turing Test, namely to conceal his identity as the engine so it can deceive people who talked with him. If the user is not able to identify bots as a computer program, then chatterbot is categorized as artificial intelligence.
Although many bots that seem to be able to interpret and respond to human input, actually the bots only scan for key words in the input and with key words that most suitable, Or the pattern of the words that most similar from textual data base.
