Sentiment analysis multiple Pdfs
I am a master's student in Business Economics and I'm new to RapidMiner.
For my thesis, I have to pre-process multiple Pdf files by tokenizing, stemming, transforming cases etc.
If I do this for one file, I get the wanted outcome: a processed text. But when I use the loop function to process multiple pdfs, the output is never text, but tables of word counts.
How do I pre-process multiple pdf files and get all the processed texts?
Thank you for helping!
