ELIZA was a text messaging-based agent, which worked on pattern matching and substitution methodology. He began working at MIT Artificial Intelligence Laboratory in 1964 and released the first known chatbot ELIZA in 1966. 1966įourteen years after the introduction of the Turing Test, Joseph Weizenbaum began working on a program that would pass the Turing Test. Even today, new systems still have to challenge the test. The Turing Test was a motivation for the following developments. Though Alan Turing did not invent the chatbot, his thoughts are still central to many discussions about artificial intelligence. If he fails to tell which of the two parties is a machine, the machine passes the Turing Test. He interacts with the two parties through textual messages, and his job is to identify the machine, using any variation of messages. But the subject knows that only one of the two parties is a machine. The test subject does not know upfront which a party is a machine and which one is a human. One is another human, and the other is a machine. The Turing Test consists of a human test subject, interacting with two parties via textual messages. The paper discussed some of the fundamental concepts in chatbots, including the Turing Test, a method to determine whether a machine possess human-like intelligence or not. 1950Īlan Turing’s 1950 paper “Computing Machinery and Intelligence” is considered the first milestone in the chatbot’s history. This post will present a brief history of chatbots from the 1950s until today. According to Google, chatbots will have a near human-level lingual ability by 2029. About 1.4 billion people in the world use messaging apps and are willing to talk to chatbots.Įstimates suggest that the use of chatbots will result in cost savings of more than $8 billion annually by 2022, up from $20 million in 2017. Nearly 45% of end-users today prefer chatbots as the main means of communication for customer service inquiries. Reports suggest that there are more than 300,000 different chatbots on Facebook alone.
