Most recent work (Cahill et al., 2013;Rozovskaya & Roth, 2011; has used machine learning methods that rely on a GEtagged corpus such as NUCLE, Japanese English Learner corpus, and Cambridge Learner Corpus (Dahlmeier et al., 2013;Izumi et al., 2005;Nicholls, 2003), because well-formed and GEtagged approaches are closely related to each other, can be synergistically combined.
research using both types of data has also been conducted (Dahlmeier & Ng, 2011).
