This data is sourced from the "Blog Authorship Corpus", available here. The original dataset was tokenized and split into sentences using spacy. Sentences with less than 5 tokens and sentences with more than 30 tokens were discarded. Number-like tokens were replaced by "<#>". Tokens other than the 9999 most common tokens were replaced by "", for a vocabulary of 10000 words. Sentences were tagged with the gender (0 for male, 1 for female) and age bracket (0 for teens, 1 for 20s, 2 for 30s) and placed into a pandas dataframe.
