Anyone know any good resources/books on AI? More specifically AI with PHP?
Something I would like to study to some depth.... my friend was telling me about an AI project he did that invloved scanning pages of text and determining nouns, adjectives, verbs etc tec... and the engine has to be clever enought o work out the context of the sentence.
i.e.
The girl looked at the moon with the telescope
Did the moon have the telescope or did the girl?
Sounds like a fun challenge

Technically there would be a comma to indicate who owns the telescope
The girl looked at the moon, with the telescope.
Indicates the girl owns the telescope.
The girl looked at the moon with the telescope.
Indicates the moon owns the telescope.
But to be ultra pedantic, the correct sentance would be:
The girl looked at the moon, through the telescope.
And as with all pedant posts, I await eagerly to be corrected

Yeah OK poor example but you know what I mean

i dont know if its available but is there any documentation on how ALICE was programmed, or better yet the source code? I would imagine that would be the best place to start as you would see how they interpreted the input.

I don't think you need the comma if you use the word 'through'.

ALICE uses a lot of predefined stuff. I remember one called LEO that learned by "chatting with you", it started out knowing nothing and learned things through context, so you could technically teach it any language, or just make up a language altogether. After a while though it knew the context for too many things and just spat our run on sentences.

I've seen a couple of nice demo's on AI. A robot that could only make a couple of basic movements get "cookies" when he moves in the right direction (particular sequence of movements).. At first he only crawls... but after a while he really runs
Will dig in my archive to find the slides etc...

That sounds awesome

Cookies?
Screw cookies.
ASIMO owns you.

George is a nice chatbot that learns from user input. That's the excuse for his sometimes bad temper and rude answers. He even swears!
The clou is that it doesn't have a word/phrase database but learns purely by analising user input through its killer sentence analysing "skills". I've managed to have a more or less coherent conversation in English, Polish (lots of swearing), French (lots of swearing too), and German (a bit of swearing and name-calling). The best conversation was in English, of course, since the proportion of non-swearing people is lowest - ie. more "normal" English-speaking people use it than from any other language background.

Thats scary

Where will we be at in 20 years time?
Gonna have a play with this george thing... looks interesting...

Btw, that honda stuff was in those slides too... But for some reason the server seems to be unreachable at this moment (probably because this night we're experimenting with openmosix running a clusterfarm of 400+ nodes

)

Would have posted yesterday but I had to go home and check the full title of the book!
I read a lot of Artificial Intelligence: A New Synthesis (by Nils J Nilsson) a few years back. It gives you a good grounding on the priniciples and theory of AI and it's various applications. As far as I remember it doesn't teach you how to apply it to your own code, but it does cover well known AI projects like ALICE. It was published in 1998 so it's probably a little dated, but its a good place to start if as you say, you want to go into the subject in some depth.
I can't remember a lot of it now, but I do remember getting a great mark for the end of term exam so I must have understood quite a bit!
