I have a list of websites that I want to "categorize" in categories
such as:

Finance
Business
Entertainment
Art
Computers
etc. etc. etc.

I want a piece of software or even better, an open-source script or
prgram that will automatically categorize these sites.  This is
similar to a search engine and would involve some sort of contextual
or semantic work, but I want the website "categorized".  A very-low
price commercial service is also an option.

If you have any questions, please ask for clarification.  Thanks.
