Question about Text Mining Processes
i would be very thankful for some kind of help! I am new at RM. So i want to do a kind of Sentiment Analysis in Social Media. I have a word list with words ranked negativ and positiv (rows in excel sheet: id, text, sentiment) . And now want to do a model where i can input a new excel sheet (rows : id,text). So in this document are e.g. comments from Facebook.
I did the following! But there is the error: The input example set does not match the training example set. Missing attribute!
