2014年Chatbot编程比赛

Chatbot编程比赛

 

这次编程比赛要求参与者编写能与用户对话的聊天机器人。我们的聊天机器人以Samantha的个性为蓝本(2013年电影《她》里的角色)。下面是一个对话的例子:

Enter user name: theo
SAMANTHA: Welcome back
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.
