[SOLVED] How to prevent some words to be stemmed?
I am having some problems with the Stem operator. It looks like the operator is stemming some brand names which contain a dictionary word in it. The result of that is that my text classification model is not as accurate as I think it would be if the brand name is maintained as it is.
Is there any way I can apply the stemm operator to all words except from some?
Thanks a lot for any tip in the right direction, I am pretty new with RapidMiner so excuse me if this is some basic question.
