AI chat program I am working on...

[Systemerror]

AI Chat:


This is something I started working on when I wanted a little break from coding my game, I decided to pracice some AI techniques, not like I do on games with pathfinding etc, but more with deterministic algorthims and FSM etc, this is basically a virtual chat program the works only on artificial intelligence to make a conversation with you, it's very early stages but it has some pretty slick programming in there (C++) so like most things I do it's open source - enjoy.

lol, quite interesting but if you keep going like this, all your code will get swamped with IF-ELSEs

Ideally, the AI would be able to pick out key "topic" words/terms and deduce the meaning of a sentence based around the words preceding/following it.
Neural-Nets could be a possibility to achieving it.

But easier said than done though (I'm sure you'd agree)
You've only just started so its always good to consider how you could develop it further.

Heres some neural net code I posted ages ago, can't say if it will be very useful though

[Slippy]

Code: Select all

    cout<<"Tell me a little about yourself "<<UserName<<":\n";
    cin>>GeneralStringInput;

May i suggest replacing "cin>>GeneralStringInput;" with something like getline(cin, GeneralStringInput);

Most people can't describe themselves well with one word

Bot: Tell me a little about yourself.
Me: Blunt.

You might want to check out Billy. It's an AI chat program. It's pretty fun. For older versions, the source code is available, if you want to take a peek how things are done.

Yeah this isn't really AI chat is it.. You certainly want the AI to be doing some thinking and trying to figure out what the person is saying rather than just hard coded if-else statements.

I remember Eliza from one of my AI courses at Uni... I seem to remember she was pretty primitive and doesn't make a huge amount of sense but i think there was something a bit more clever going on under the hood than yours, might be worth checking out!

check out this.

Well they got that Alan guy just about right for the internet... Started asking me about my childhood and stuff...

i suggest when doing some kind of ai program dont use a procedural language you should use more like logical language it will be easier to look posibilities results etc.
The thing is slower than procedurals language so you gotta be got at refining the code if you have question or are interested in logical languages you can ask me

[twilight17]

I could see a use of Boost::Regex here

Prolog FTW
