We use 3 baselines: (i) our implementation of (Watanabe et al., 2006) : LR-Hiero with beam search (LR-Hiero) and (ii) LR-Hiero with cube pruning (<cite>Siahbani et al., 2013</cite>) : (<cite>LR-Hiero+CP</cite>); and (iii) Kriya, an open-source implementation of Hiero in Python, which performs comparably to other open-source Hiero systems (Sankaran et al., 2012) .
