A Ruby implementation Joseph Weizenbaum's ELIZA, your friendly neighborhood robo Rogerian psychotherapist.

This is a work in progress. The rules needs a bit more work before it's ready for 1.0. In the meantime have fun and let me know how it goes.

This is what it looks like chatting with her,

ELIZA: Please tell me what's been bothering you.I have problems sleeping every night. ELIZA: That's quite interesting.It's not really interesting. More bothersome than anything. ELIZA: What does that suggest to you?I think it means that I've been having bad dreams. ELIZA: You say you think it means that you've been having bad dreams?Yes, exactly. ELIZA: I understand.But how can you? You're a computer!ELIZA: What about machines worries you?

TBD

eliza=Eliza::Bot.newinitial=eliza.initial_phrasereply=eliza.transform(input_string)# `#transform` returns a final phrase in case of a quit phrase# but you can also get a final phrase with:final=eliza.final_phrase

You can chat with ELIZA on the CLI by running:

./bin/eliza-rb

If you already have Docker installed, here's how you can get started:

• docker build -t eliza-rb github.com/tansengming/eliza-rb
• docker run -it eliza-rb

ELIZA works by matching keywords and using those keywords to form replies witha bunch of rules:

Let's sayforget is a keyword with decomposition and reassembly rules that look like this:

{decomposition_pattern:"* i forget *"reassembly_pattern:Can you think of why you might forget \2?}

If we start off with a sentence like:

What if I forgetabout the kettle?

Applying the rules would create this reply:

Can you think of why you might forgetabout the kettle?
