How to map a keyword to a category?

Question

I have a bunch of general categories, such as: Games, Modeling, Business, Finance, etc.

My question is, how can I take a keyword such as "Xbox 360" and automatically map it to a category such as "Games"? This is an easy example, and I did figure out ways to do this, but if I take a harder example such as "Tyra Banks", I am unable to map it to a category of mine such as "Modeling" or "Tv Shows".

I have been thinking of this for a very long time, and I can't come up with a concrete solution. I have also searched the web and found nothing that would provide this service.

Any ideas?
