“…These methods can be classified into three categories: unsupervised approaches (Goldsmith, 2001) (Creutz and Lagus, 2002) (Creutz et al, 2007) (Poon et al, 2009) (Abudukelimu et al, 2017), supervised approaches (Sirts andGoldwater, 2013) (Ruokolainen et al, 2013) and semi-supervised approaches (Kohonen et al, 2010) (Ruokolainen et al, 2014) (Tursun et al, 2016). Other people also put their efforts on morphological segmentation for SMT, such as (Lee, 2004) (Grönroos et al, 2016) (Mermer andSaraclar, 2011) (Sereewattana, 2003) (Clifton, 2010) (Bisazza and Federico, 2009) (Al-Haj and Lavie, 2012) (Rasooli et al, 2013) (Mi et al, 2015).…”
