Statistics of our datasets. “Treebank” is the UD treebank identifier, “#Token” is the number of tokens, “%Punct” is the percentage of punctuation tokens, “#Omit” is the small number of sentences containing non-leaf punctuation tokens (see footnote ¹⁹), and “#Type” is the number of punctuation types after preprocessing. (Recall from §4 that preprocessing distinguishes between left and right quotation mark types, and between abbreviation dot and period dot types.)
