Based on video http://vancouverdata.blogspot.in/2011/10/rapidminer-text-mining-r-analytics.html , I have built below model

But it is not working. Can someone suggest?

Can you please be more specific on "it does not work"? Does the proces not run at all, or does it not deliver the expected results? Please read the post linked in my signature on how to ask good questions.

Best, Marius
