Words found in the corpus before stopwords removal and stemming are printed, together with
the corresponding stemmed term that was eventually added to the document-term matrix, if stemming
was enabled. Occurrences found before and after stemming are also shown. The column Stopword? indicates whether the corresponding word is present in the list
of stopwords for the corpus language. Words that were actually removed, either automatically by
stopwords removal at import time, or manually via the Text mining->Terms->Exclude terms from analysis...
menu, are signalled in the Removed? column. All other words are present in the final
document-term matrix, in their original or in their stemmed form.
