Works using the pipeline approach in SDS tend to focus on sentence planning, improving a handcrafted generator (Walker et al., 2001; Stent et al., 2004; Paiva and Evans, 2005) or using perceptron-guided A* search<cite> (Dušek and Jurčíček, 2015)</cite> . We extend the previous works by generating deep syntax trees as well as strings and directly comparing pipeline and joint generation.
