Hello!
I have a question regarding basic text pre-processing. My workflow works but the bag of words is creating an empty table.
WARN Bag of Words Creator 2:47 Node created an empty data table.
The workflow looks as follows:
XLS reader - strings to document - punctuation erasure - number filter - case converter - stop word filter - RegEx filter - bag of words creator
Could you please suggest what might be wrong?
Thank you!
Lena
