I have a project which I will turn documents of a corpus into doc2vec. I was reading that when people convert a document to bag of words they try to improve the bag of words by removing stopwords, lemmatizing, and stemming.
I was going to do this for my doc2vec preparation but I was reading that it is not necessary to lemmatize and stemming. So, I just removed the stop words. Does anybody have experience with doc2vec and what the best pre-processing steps that will make the best doc2vec represenation?
