ELIZA, AOLiza and A.L.I.C.E.

• The Quest to Pass the Turing Test
• By Steve Sepanloo

2
A Little Background On Turing Tests

• Created by Alan Turing in the 1950s as a method
  for testing the intelligence of a computer
• Based upon human asking questions to a computer
  and to another human, and if the reply is
  indistinguishable, then the computer has passed
  the Turing Test and is Intelligent
• Imagine The Dating Game

ELIZA

• Invented in 1966 by Joseph Wiesenbaum
• Somewhat passes the Turing Test, because it uses
  Rogerian therapy and gives the user a somewhat
  reasonable response
• Rogerian Therapy The process of responding to a
  patients statements with a question referring to
  that statement
• Failed because this only fools a human for a
  short period of time

AOLiza

• Created by Kevin Fox, a tester for AOL
• Fairly recent development, uses chat window to
  incorporate chatterbot
• Though more sophisticated, the results of fooling
  humans and thus passing Turing Test are
  misleading
• If the user does not expect to be encountering a
  computer, than the Turing Test is not truly being
  run
• One form is SmarterChild on Aim
• Uses Perl Script running in background to check
  keywords in a log file created by AppleScript,
  the keywords are then formed into questions and
  sent back to the user

A.L.I.C.E.

• Artificial Linguistic Internet Computer Entity
• Won the Loebner Award (Award given to best
  chatterbot) several years in a row
• Has a vastly larger database of keywords and
  logical responses
• However, still fails true Turing Test, as when
  two machines are tested against each other, the
  machines have no idea where the conversation, or
  for that matter if the machine recognizes when
  the conversation is nonsense

Example

• Alice1 Hello there.Alice2 Salutations,
  OmAlice1 Greetings, Human.Alice2 Hi
  there!Alice1 Hello OmAlice2 Hello there. I
  have no answer for thatAlice1 Would you like to
  have it?Alice2 Why don't you just download me?

Future?

• Chatterbots paving the way in the field of
  Artificial Intelligence
• Future brain-like organization, with computer
  program analyzing patterns of paragraph
  organization rather than just keywords or
  sentences
• This allows the machine to understand when the
  conversation no longer makes sense
• Perhaps no longer will you decide if you still
  want to talk to the chatterbot, rather it will
  decide if it still wants to talk to you
