Eliza

• Eliza was built in the 60s. Have you tried it?
• The chatbot acts as a therapist.
• It drives the conversation by asking the user questions.
• The underlying algorithm is pretty simple.
• It pulls certain phrases out of the user's input.
• For instance, it looks for family members.
• It then asks questions about those certain phrases.
• For instance, if the user has said "My mother is bothering me.", Eliza will respond "tell me more about your mother".
• It will say the same thing in response to "It's a real mother for ya, yeah."
• Yorick Wilks has a paper on how it's important for a system to control the conversation to make it easier to be seen as human.
