Automatic Keyword Generator

Hi all,
Is there such a thing as an intelligent Automatic Keyword Generator, that can be used in Adobe Bridge.
I have recently obtained a vast number of images that I need to categorise.
My normal procedure would be to assign keywords when I import an image,. But on this occasion there are just 100's and I'm looking to see if there is a recognition programme that can automate the process.
I'm using Bridge & Photoshop CS6. I don't have Lightroom.
TIA
