Existing works on the analysis of writing revisions (Adler et al., 2011;Bronner and Monz, 2012;Daxenberger and Gurevych, 2013;Zhang and Litman, 2015) typically compare two versions of a text to extract revisions, then classify the purpose of each revision in isolation.
while limited contextual features such as revision location have been utilized in prior work, such features are computed from the revision being classified but typically not its neighbors.
