"Text Mining Generate n-germs giving me bad results"
First time user of RapidMiner so be gentle.
I have a file of support call notes that I'm trying to text mine to get the most used 2-word phrases. I've watched a couple of videos and read a couple of posts on how to do this. So I think I have everything set correct (but maybe not since it's not working). Before using Generate n-germs, the process returns single words just fine. After I add Generate n-germs with max length of 2. The below screen caps give a peek into my set up and results.
Any help or direction would be greatly appreciated.
