Process Document from Data
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
