Chatter Bots are computer programs that talk via dialogue or text. They can simulate human conversation and pass the Turing test. Chatbots can be used for practical purposes, such as customer service or information acquisition. Some chatbots are equipped with natural language processing systems, but most are simple systems that only capture the keywords entered and then search the database for the most appropriate response sentence. Currently, chatbots are part of virtual assistants (such as Google Assistant) and can connect with many organizations' applications, websites, and instant messaging platforms (such as Facebook Messenger). Non-assistant apps include chat rooms for entertainment purposes, research and product-specific promotions, social robots.
