The prediction of the compositionality of MWE types has traditionally been couched as a binary classification task (compositional or non-compositional: Baldwin et al. (2003) , Bannard (2006) ), but more recent work has moved towards a regression setup, where the degree of the compositionality is predicted on a continuous scale (Reddy et al., 2011;<cite> Salehi and Cook, 2013</cite>; Salehi et al., 2014) .
