"getting started with text-mining"

Hi,

I want to take a look at the text-mining part of the rapid miner. I am evaluating some products as part of a case study about text-mining.

So what I want to do is:

• to get data input from file/web (I did this with the input and the crawler)
• to get the feature extraction running -> I can excract here some entities, right?
• to get the english stop word filter running

I don´t know why but the feature extraction  doesn´t work with the text I´m using for my input. Can you give me or show me a quick tutorial how to use these things?

Thanks a lot!

Benjamin
