text mining problem

Mohamad1367 · June 2020

hi dear community
i have a question about filter stop word (dictionary) operator that i asked in previous post but didn't answer anyone. when i apply this operator after tokenizing the eaxample set i don't recieve filtered output what is the cause of this problem?

Are you sure there are tokens in your dataset that are also in your stopwords dictionary file? Is your dictionary file correctly formatted? Are you receiving any error messages? Do you have an example process? The question is pretty vague right now and without more information it will probably be difficult for anyone to provide more specific guidance.
