help regarding AI used in natural language understanding

Postposted on Sun Apr 04, 2004 12:24 am

I have gone to
http://www.bitesizeinc.net/index.php/ouija.html
Can any body tell me that what kind of neural networks are being used in this/such program and about any other techniques used in such programs?
How is it possible to understand natural languages?
Does the computational linguists follow the same pattern, like a child learns to speak and understand it mother tongue?
Can u ppl direct me to the source which explain all this stuff starting from the very basics of neural networks and then how they works, specially in this context of natural language understanding and forming new sentences?
Ur help will be greatly appreciated bcz I know the forum is full of computer geniuses.
thanks

Same way that horiscopes are done, and ad-libs. You come up with canned vague responses, leave a few words blank that get filled in from weighting by previous responses/questions. The individual response is triggered by key words, as well as previous responses.

I think...

It's just doing canned reply's for the first word you give it.

Actually I know that the responsive sentences are hard coded.
They say that AI has been used in this soft ware but I think that it is an expert system, which selects a suitable sentence as a response of your input on the basis of some key words.
This can be done, by using some kind of decision trees.
Any how
I am not sure about the job being done behind the screen, that’s why I asked about the type of "neural nets"/"any other technique" used in this or such programs.

Rests of my questions are independent of this site.
1. How is it possible to understand natural languages?
2. Does the computational linguists follow the same pattern, which a child adopts to learn, speak and to understand it mother tongue?
3. Can u ppl direct me to the source which explain all this stuff starting from the very basics of neural networks and then how they works, specially in this context of "natural language understanding" and forming new sentences

2nd and 3rd questions can also be summarized as:
Is it possible to use adaptive neural nets to learn and speak natural languages?
Thanks for your interest.

Its possible, but no one has done a convincing enough simulation. Simply because of the vast amount of combinations of a word that can used, punctuation, word context, spelling errors, grammer style.

The thing about languages is that its a learning process that takes even humans around 2-3 years. Right now, the fastest computers the size of a city will be required to equal a human brain in computational power. Hence, complex language is not something that can be taught to a computer overnight. The advantage that computer has is that if 1 computer learns it, all other computers can learn it also.

Even a minute work is also important for me. So kindly tell me every thing that u know about the research in this field.
Consider the situation that of a boy who loses all of his senses except speech and hearing.
Now he is left with memory and brain only.
How is he going to learn language?
Psychology and linguistics may answer this question.

I agree, rather I must say, even having such computer there is no surety that weather it will meet human brain or not.
Nothing can compete human brain bcz human have feelings, will power and most importantly the wisdom.

This would be a good place to start.

Thanks for this great favor.
I believe the site will really be very helpful for me.
It would be my pleasure to have more recommendations (books/sites).

That site has 10s of links which in turn link to 100s of other other websites. Took me 3 weeks to cover all the material in the Speech Recognition section. Good luck.
