The works differ in the way they acquire morphological knowledge (from using linguistically derived morphological analyzers on one end, to approximating morphology using substrings while relying on the concatenative nature of morphology, on the other) and in the model form (cDSMs (Lazaridou et al., 2013) , RNN (Luong et al., 2013) , LBL (Botha and Blunsom, 2014) , CBOW (Qiu et al., 2014) , SkipGram (Soricut and Och, 2015; <cite>Bojanowski et al., 2016)</cite> , GGM (Cotterell et al., 2016) ).
