Generating an ngram document term matrix with TextAnalysis.jl

New to Julia

I recently wanted to do the same thing. I solved it by using NGramDocument() instead of TokenDocument():

using TextAnalysis
test = "Hello, I like apples and oranges. I like ice-cream."
test_doc = NGramDocument(test, 2)

crps = Corpus([test_doc])
update_lexicon!(crps)
m = DocumentTermMatrix(crps)
dtm(m, :dense)
