Overture Data mining

How to collect

[notbob]

I have read that Overture uses sites such as Dogpile to create their database of seach terms.

Do they have some kind of agreement with them to use their site or is there a way that we as webmasters could also use Dogpile or some other resource to create our own database of terms.

I know bandwidth and hardware requirements would probably be large, but assuming it is not an issue, is there a way we can do the same thing overture does?

Thank you
