Which is preferred use BoW node before any preprocessing filtering node? or use preprocessing filtering nodes before BoW node? Why?
some information regarding the textprocessing extension is outdated.
In previous versions (< 3.0) it was possible to do deep processing meaning that preprocessing filter nodes could be applied on a Bag of Words. Since this is not possible anymore, we need to preprocess the documents beforehand and then apply the Bag of Words Creator to the preprocessed documents at the end of the pipeline.
