Is stemming used when gensim creates a dictionary for tf-idf model?
I was also struggling with the same case. To overcome i first stammed documents using NLTK and later processed it with gensim. Probably it can be a easier and handy way to perform your task.
I am using Gensim python toolkit to build tf-idf model for documents. So I need to create a dictionary for all documents first. However, I found Gensim does not use stemming before creating the dictionary and corpus. Am I right ?
