=Version 6: Adding ''Memory'' to Eliza=
 +
<br />
 +
* To add memory to Eliza, we use the reflection, where the program recognizes answers of the form "I xxxx you" (where ''xxxx'' is some verb), and responds with "you xxxx me?", and takes this last sentence and adds it to the '''prompts''' list.  This way, every so often, out of the blue, when the program does not recognize a family matter, or a reflection, or a negative comment, it will respond with "You xxxx me?"

==Mac Version==
 +
<br />
 +
On a Mac, you can open a Terminal window and type commands of the form: ''say Hello there!'', and the Mac will "say" the sentence.  In Python, on a Mac, you can run these commands using a simple statement, as illustrated in the code below:
 +
<br />
 +
<source lang="python">
 +
import os
 +
import time
 +
 +
os.system( "say hello there!" )
 +
time.sleep( 0.5 )             
 +
 +
os.system( "say how are you today?" )
 +
time.sleep( 0.5 )
 +
 +
print( "done" )
 +
             
 +
</source>
 +
 +
<br />
 +
Below is the version of Eliza where we modified the contents of the '''myprint()''' function so that it says the answers back.

Introduction to the Turing Test


The Imitation game



Video Introduction



Introduction given by Prof. Suilin Lavelle, in Week 3 of the University of Edinburgh's "Introduction to Philosophy" (INTROPHIL) open online course.
Below are two short scenes from the movie Bladerunner, mentioned in Prof. Lavelle's video.



Eliza Program


Version 1: Let's start with something very basic


# Eliza1.py
# D. Thiebaut
# A very short beginning program for Eliza



# --------------------------------------------------------------------------
# just print the string to the console
# will be transformed to something better later...
def myprint( string ):
    print( string )
    
# sayGoodBye
# say goodbye to the user.
def sayGoodBye( name ):
    myprint( "Good bye " + name )

# isGoodBye
# checks to see if what the user said is one of the keywords for
# ending the conversation.
def isGoodBye( userAnswer ):
    if userAnswer.lower().strip() in [ "bye", "goodbye", "ciao" ]:
        return True
    else:
        return False

def greetings():
    myprint( "Hello there!" )
    myprint( "What is your name?" )
    name = input( "> " )
    myprint( "Welcome " + name )
    return name

# --------------------------------------------------------------------------
# main function
# --------------------------------------------------------------------------                   
def main():

     # greet user and get her name
     userName = greetings()
     
     # conversation: get user input, and respond
     for i in range( 1000 ):

         # get user's statement
         userAnswer = input( "> " )

         # if it is a goodbye statement, exit the loop
         if isGoodBye( userAnswer ) == True:
             break

         # tell the user to continue speaking
         myprint( "Please tell me more..." )


     # if we're here, it's because the loop stopped.
     # say goodbye to the user
     sayGoodBye( userName )
            
         
main()


Version 2: Let's randomize the program's prompts


The new code is highlighted. 

# Eliza2.py
# D. Thiebaut
# A very short beginning program for Eliza
# with random prompts from the program.
import random


# --------------------------------------------------------------------------
# just print the string to the console
# will be transformed to something better later...
def myprint( string ):
    print( string )
    
# sayGoodBye
# say goodbye to the user.
def sayGoodBye( name ):
    myprint( "Good bye " + name )

# isGoodBye
# checks to see if what the user said is one of the keywords for
# ending the conversation.
def isGoodBye( userAnswer ):
    if userAnswer.lower().strip() in [ "bye", "goodbye", "ciao" ]:
        return True
    else:
        return False

def greetings():
    myprint( "Hello there!" )
    myprint( "What is your name?" )
    name = input( "> " )
    myprint( "Welcome " + name )
    return name

# --------------------------------------------------------------------------
# main function
# --------------------------------------------------------------------------                   
def main():
     prompts = ["Please go on...", "Please tell me more...",
                "Interesting... Go on, please!", "Yes?  Really? Go on",
                "Weird... I'm not sure what to think of that..." ]
     
     # greet user and get her name
     userName = greetings()
     
     # conversation: get user input, and respond
     for i in range( 1000 ):

         # get user's statement
         userAnswer = input( "> " )

         # if it is a goodbye statement, exit the loop
         if isGoodBye( userAnswer ) == True:
             break

         # tell the user to continue speaking
         myprint( random.choice( prompts ) )

     # if we're here, it's because the loop stopped.
     # say goodbye to the user
     sayGoodBye( userName )
            
main()


Version 3: React to Negative User Answers


In this version the program will pick up on the user responding "No", or "Never", and respond differently if this is the case. The highlighted lines show the addition of new code. 

# Eliza3.py
# D. Thiebaut
# A very short beginning program for Eliza
# with random prompts from the program.
import random


# --------------------------------------------------------------------------
# just print the string to the console
# will be transformed to something better later...
def myprint( string ):
    print( string )
    
# sayGoodBye
# say goodbye to the user.
def sayGoodBye( name ):
    myprint( "Good bye " + name )

# isGoodBye
# checks to see if what the user said is one of the keywords for
# ending the conversation.
def isGoodBye( userAnswer ):
    if userAnswer.lower().strip() in [ "bye", "goodbye", "ciao" ]:
        return True
    else:
        return False

# isNegativeAnswer
# returns True if user says a single word such as "no", or "never"
def isNegative( userAnswer ):
    if userAnswer.lower().strip() in [ "no", "never" ]:
        return True
    else:
        return False


def greetings():
    myprint( "Hello there!" )
    myprint( "What is your name?" )
    name = input( "> " )
    myprint( "Welcome " + name )
    return name.capitalize()

# --------------------------------------------------------------------------
# main function
# --------------------------------------------------------------------------                   
def main():
     prompts = ["Please go on...", "Please tell me more...",
                "Interesting... Go on, please!", "Yes? Really? Go on",
                "Weird... I'm not sure what to think of that..." ]

     promptsNegative = [ "Such strong words!", "Really?", "Why?",
                         "My, we are so negative today!", 
                         "You really think so?", "Why not?" ]
     
     # greet user and get her name
     userName = greetings()
     
     # conversation: get user input, and respond
     for i in range( 1000 ):

         # get user's statement
         userAnswer = input( "> " )

         # if it is a goodbye statement, exit the loop
         if isGoodBye( userAnswer ) == True:
             break

         # tell the user to continue speaking
         if isNegative( userAnswer ) == True:
             myprint( random.choice( promptsNegative ) )
         else:           
             myprint( random.choice( prompts ) )


     # if we're here, it's because the loop stopped.
     # say goodbye to the user
     sayGoodBye( userName )
            
         
main()

Version 6: Adding Memory to Eliza


  • To add memory to Eliza, we use the reflection, where the program recognizes answers of the form "I xxxx you" (where xxxx is some verb), and responds with "you xxxx me?", and takes this last sentence and adds it to the prompts list. This way, every so often, out of the blue, when the program does not recognize a family matter, or a reflection, or a negative comment, it will respond with "You xxxx me?"

Version 7: Make Eliza Talk!


Mac Version


On a Mac, you can open a Terminal window and type commands of the form: say Hello there!, and the Mac will "say" the sentence. In Python, on a Mac, you can run these commands using a simple statement, as illustrated in the code below: 

import os
import time

os.system( "say hello there!" )
time.sleep( 0.5 )              

os.system( "say how are you today?" )
time.sleep( 0.5 )

print( "done" )


Below is the version of Eliza where we modified the contents of the myprint() function so that it says the answers back.

    # wait 0.5 seconds to give the program time to say the
    # sentence
    time.sleep( 0.5 )
    
# sayGoodBye
# say goodbye to the user.
