Excuse me for being stupid, but where is your website?
Gravi.tation.tk

The files are chat.php and chat.dat.

Is it just me, or do the tabs on the left do nothing?

transparent · 2012-10-14 13:29:22

I still can't connect to it. I've had trouble connecting with some .tk domains.

It could be a anti-virus thing hmm

They do nothing, I'm not done with the website yet; I have nothing to put on there.

This is still my favourite chatbot:
Code:

messages = []
while 1:
    messages.append(raw_input("? "))
    print random.choice(messages)
I knew you would post here, since you're a Python programmer.

I found the thread eventually... tongue

I did make a learning chatbot once that automatically built a dictionary of inputs versus lists of possible responses as you talked to it. It would add your replies as possible responses to the last thing it said, if that makes sense. I wrote an interface for an anonymous chatroom and got it to learn from random strangers... It generated some very amusing chat logs big_smile

The trick was to use fuzzy string comparison (called Levenshtein distance, if you're interested) when comparing the current input against the dictionary. It compared sentences, and then words, and then letters (exactly the same was 1.0, upper/lowercase of the same letter were set as 0.8 similar, for example, and so on).

It picks a random response from the input with the best match. Below a certain threshold (about 0.4, iirc) it just gives a random response.

So as a result, if it says "How are you?", and you say "Fine, thanks!" in reply, it will then respond to "how're you today" (or similar) with "Fine, thanks!".

So, there are my thoughts tongue I could post code if you're interested (:

Very interesting stuff! Can I see the code?

Hmm, fuzzy comparison. I need to know how to do that.

I just found a Levenshtein distance algorithm on the internet... tongue

Sure, I'll clean it up a bit and post it here.

In the meantime, here's a sample conversation, starting from a blank memory:

Code:

YOU: Hi!
BOT: Hi!
YOU: How are you?
BOT: How are you?
YOU: I'm alright, thanks. How are you?
BOT: I'm alright, thanks.
YOU: Good! Let's have a party.
BOT: Good!
YOU: Yes.
BOT: How are you?
YOU: Good, thanks!
BOT: Let's have a party.
YOU: Yes, let's!
BOT: Yes, let's!

tongue

(It gets better, honestly...)

It's some of the messiest code I've ever written, by virtue of being the product of my procrastination for exams the summer before last... tongue

Hrm. It immediately closes after it opens. Something about JSON. hmm

Which Python are you using? Did you run it from terminal? You need to pass an argument telling it where to save its memory, like

Code:

python chatbot.py memory.json

Thanks.

But seriously, I'm new to programming (not Scratch, though); I have no idea how most of the stuff works. tongue
