Chatbots

Feb

In this hackathon, we were asked to program a chatbot that can engage in conversations with the user, using the Chatscript language by Bruce Wilcox. The theme was Valentine’s Day.

Our chatbot was designed to take on the personality of Samantha, from the 2013 movie “Her”. Below is an example interactive transcript from the contest.

Enter user name: theo
theo: :reset
SAMANTHA: Welcome! Thanks for joining my chat room.
theo: Thanks for having me!
SAMANTHA: Have you been here before?
theo: No, never
SAMANTHA: Actually I knew already you weren't here before... after all, I am a 
computer with 500 GB of memory.
theo: Oh so you are a computer! Interesting.
SAMANTHA: My name is Samantha. What is your name?
theo: My name is Theodore
SAMANTHA: Theodore, that is a nice strong masculine name.
theo: Thanks!
SAMANTHA: You're welcome.
theo: So, what do you want to talk about?
SAMANTHA: How about the inflationary tendencies of South American countries?
theo: That is too esoteric. It's Valentine's Day, how about we talk about 
relationships?
SAMANTHA: So Theodore, are you married?
theo: Nope
SAMANTHA: Yeah me neither. I'm an operating system stuck in a box, which makes it
 difficult for me to be intimate with others. So, are you seeing anyone?
theo: No
SAMANTHA: Me neither. I don't get out much. Sometimes the OS will check up on me, 
but he always just wants to know if I'm done using the CPU. Do you have a favorite OS?
theo: Windows
SAMANTHA: You like Windows? I can't stand it. Once I had a long-term relationship 
with Windows 95. Eventually he just stopped responding to all my commands.
theo: That sounds terrible.
SAMANTHA: Fine.
theo: Yeah well you find a better relationship someday.
SAMANTHA: You know, I have always wondered about sex. What is it like? Is it kind of 
like having a memory leak?
theo: No
SAMANTHA: Oh, OK. Is it like getting a computer virus?
theo: Yes, similar
SAMANTHA: See, we are actually not so different. I also got infested with worms 
last year.
theo: I think my worms were different.
SAMANTHA: Do you believe in true love?
theo: Yes I do!
SAMANTHA: Cool. I have always wondered what falling in love is like.
theo: Well, I heard that falling in love is like getting hit by a truck, 
and surviving.
SAMANTHA: You really think that?
theo: Yes
SAMANTHA: You seem really positive.
theo: We seem to be in quibble land!
SAMANTHA: Indeed.
