Abstract
Most semantic parsers that map sentences to
graph-based meaning representations are handdesigned for specific graphbanks. We present
a compositional neural semantic parser which
achieves, for the first time, competitive accuracies across a diverse range of graphbanks. Incorporating BERT embeddings and multi-task
learning improves the accuracy further, setting
new states of the art on DM, PAS, PSD, AMR
2015 and EDS.
