... Australia Abstract Many semantic parsing models use tree trans- formations to map between natural language and meaning representation. However, while tree transformations are central to several state- of-the-art ... tree transformation based se- mantic parsing can benefit from the literature on for- mal language theory and tree automata, and have taken a step in this direction by presenti...
