Hello, Everyone!
I am very beginner in rapid miner and doing a sentiment analysis on tweets. I have a problem at a basic level. I am using a tool process document data to generate tf-idf vector and word counts after cleaning the tweets. I have opened an excel file which containing 2000 tweets with reading excel operator and passes these data to nominal to text operator and select the text attribute for generating the matrix. when I am running my process the process document data not showing the result which I am expected a term frequency matrix instead it showing simple data as I loaded in excel sheet.
I am using rapid miner 8.1.001 version

@waqaskhan343 I see you have toggled on 'select attributes and weights' on the Process Doc operator and not entered anything. That's probably your problem. Toggle that off and run again.

@waqaskhan343 you should post your XML of the process to help us. Did you put a Tokenize operator inside the Process Documents operator?
thank you in advance

@waqaskhan343 please edit your previous post and use the </> code format button. This ensures proper rendering of your XML code.
Also, it's RapidMiner, not Rapid minor.
@Thomas_Ott ROFL =D as I mention I'm new in rapidminer
I have uploaded the code.
@Thomas_Ott oh yes its working now so the problem is that check on attributee
thank you so much you save my life. thank you again and again, sir @Thomas_Ott
wow - well done @waqaskhan343 for learning how to post XML and getting your question answered by resident unicorn @Thomas_Ott!
I almost want to send you some RapidMiner swag gifts for this...
