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.new
initial = eliza.initial_phrase
reply = 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_phraseYou 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-rbdocker run -it eliza-rb
ELIZA works by matching keywords and using those keywords to form replies with a bunch of rules:
Let's say forget 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 forget about the kettle?
Applying the rules would create this reply:
Can you think of why you might forget about the kettle?
