            Removing stopwords from R data frame column
            Asked 2020-Dec-22 at 01:57

            Here's the situation, one whose solution seemed to be simple at first, but that has turned out to be more complicated than I expected.

            I have an R data frame with three columns: an ID, a column with texts (reviews), and one with numeric values which I want to predict based on the text.

            I have already done some preprocessing on the text column, so it is free of punctuation, in lower case, and ready to be tokenized and turned into a matrix so I can train a model on it. The problem is I can't figure out how to remove the stop words from that text.

            Here's what I am trying to do with the text2vec package. I was planning on doing the stop-word removal before this chunk at first. But anywhere will do.

            text2vec word embeddings : compound some tokens but not all
            Asked 2020-Oct-05 at 04:08

            I am using {text2vec} word embeddings to build a dictionary of similar terms pertaining to a certain semantic category.

            Is it OK to compound some tokens in the corpus, but not all? For example, I want to calculate terms similar to “future generation” or “rising generation”, but these collocations occur as separate terms in the original corpus of course. I am wondering if it is bad practice to gsub "rising generation" --> "rising_generation", without compounding all other terms that occur frequently together such as “climate change.”

            Thanks!

            Yes, it's fine. It may or may not work exactly the way you want but it's worth trying.

            You might want to look at the code for collocations in text2vec, which can automatically detect and join phrases for you. You can certainly join phrases on top of that if you want. In Gensim in Python I would use the Phrases code for the same thing.

            Given that training word vectors usually doesn't take too long, it's best to try different techniques and see which one works better for your goal.

            text2vec's vocab_vectorizer ouput is the function itself

            I am trying to run through text2vec's example on this page. However, whenever I try to see what the vocab_vectorizer function returned, it's just an output of the function itself. In all my years of R coding, I've never seen this before, but it also feels funky enough to extend beyond just this function. Any pointers?
