getting somewhere....

I found some stuff on Daniel Shiffman's site about Bayesian Filtering, whilst i don't understand it completely i think it's what i've been looking for. Using Hashmaps you can search a document for words, and have the program state that it's found or how many times it's appeared etc. It's the system used to detect spam coming into your inbox.

I've found a relatively simple example in java, and a bit more complex version in Processing. i'm hoping to mush the two together to get a bit of code that works.
