1. ELIZA is considered as first Chatbot developed in 1966(Weizenbaum, 1966)
2. Was able to fool user in believing them to have conversation with human
3. Works on a principle of recognizing the words from sentence and giving a pre programmed
or pre prepared output on the basis of recognized words
4. Alan Turing proposed a paper called “Turing Test” that is considered as a criteria of
Intelligence(Turing, 1950)
5. ELIZA was the first to pass this test

13. Evolution(Six Stages)
1. The Character Actor
• Look for key phrases in user’s text or speech and based on it give output of scripted
responses
2. The Assistant
• Narrow down the task and assigned to do that particular task only
• Each task represented with a form. Similar to stage 1 but rules has been split down
the middle into two set of rules. One set looks for key phrases and other set checks if
form is filled. If yes calls web services. Started from late 90s
• Used for ordering pizza, making reservation

14. … contd
3. The talking encyclopedia
• No longer require predefined form
• Build up a representation of what you mean by word by word(Semantic Parsing)
• Used for weather forecasting, finding chinese restaurant nearby
• Google’s Syntaxnet is one of the example
4. The Historian
• Above this stage bots are not good at understanding how the given sentences connects to one another
• Maintains discourse history
• Integrate gesture understanding with language understanding

15. … contd
5. The Collaborator
• In Earlier stage chatbot recognizes the task that needs to be performed but it really
cannot relate what user are actually trying to achieve
• This stage of chatbot will suggest and recommend the best possible option using AI
6. The Companion
• Similar to Human Counselor
• Inspired from movie “Her”
