There is a significant literature in sentence compression aimed at modeling the first of these, length: producing meaning-preserving alternations that reduce the length of the input string (Chandrasekar et al., 1996;Vanderwende et al., 2007;Clarke and Lapata, 2008;Cohn and Lapata, 2009;Yatskar et al., 2010).
we know of no previous work aimed at modeling meaning-preserving transformations that systematically transform the register or style of an input string.
