Eliza Bot

(Copied from elisabot-js)

What is this?

• JavasScript bot based on Eliza - www.masswerk.at/elizabot and http://en.wikipedia.org/wiki/ELIZA

ELIZA is an early natural language processing computer program created from 1964 to 1966[1] at the MIT Artificial Intelligence Laboratory by Joseph Weizenbaum.[2] Created to demonstrate the superficiality of communication between man and machine, Eliza simulated conversation by using a 'pattern matching' and substitution methodology that gave users an illusion of understanding on the part of the program, but had no built in framework for contextualizing events.[3] Directives on how to interact were provided by 'scripts', written originally in MAD-Slip, which allowed ELIZA to process user inputs and engage in discourse following the rules and directions of the script. The most famous script, DOCTOR, simulated a Rogerian psychotherapist and used rules, dictated in the script, to respond with non-directional questions to user inputs. As such, ELIZA was one of the first chatterbots, but was also regarded as one of the first programs capable of passing the Turing Test.

Usage

var elizabot = require('./elizabot.js');
elizabot.start()          // initializes eliza and returns a greeting message
elizabot.reply(msgtext)   // returns a eliza-like reply based on the message text passed into it
elizabot.bye()            // returns a farewell message

Example output

node index.js

Hi
I see. Tell me more.
---
I am tired
Do you know anyone else who is tired ?
---
Yup
Do you feel strongly about discussing such things ?
---
Very likely
What does that suggest to you ?
---
no
You are being a bit negative.
---
Because it makes me feel better
Does that reason seem to explain anything else ?
---
not really
Please go on.
---
Maybe we could discuss this moreover in our next session ?   Goodbye.

Example output

node index.js

Hi
Now we are getting somewhere. Explain more.
---
I am tired
Do you believe it is normal to be tired ?
---
Yup
I'm not sure I understand you fully.
---
Very likely
I see. How does that make you feel ?
---
no
Are you saying no just to be negative?
---
Because it makes me feel better
Is that the real reason ?
---
not really
Does talking about this bother you ?
---
This was a good session, wasn't it -- but time is over now.   Goodbye.
