Character Recognition

a step up from character length recognition

[cmatcme]

In one of my previous posts I asked about Character Length Recognition [webmasterworld.com].

Now it wish to recognize individual characters.

ie

If toggle was typed in Then
it was recognize it there was 1t, 1o, 2g, 1l, 1e
End If

Like that.

look up information on the "charat" functions in javascript.

you could count the chars, then write a loop to increment through the word, storing the results n variables. it would be a pain of a script but it's possible.

[cmatcme]

Hmmm.

Very very hard.

Let's put it another way. If I were to type msuic into google it would come up with:

Did you mean music?

How does g do that. Would it be using charat?

[txbakers]

oh! that would be a MAJOR, MAJOR, MAJOR undertaking. There's a reason google has close to 600 employees.

[cmatcme]

Oh OK. I'll forget about it then.

[cmatcme]

How would you start about undergoing it? I presume you would store all words in a db.

[txbakers]

Yes, all words and all conceivable misspellings.

Sysiphus had an easier job.

then throw probability into the mix and you've got yourself a real barn burner of a problem
