The DipInfoUniTo Realizer at SR'19: Learning to Rank and Deep Morphology Prediction for Multilingual Surface Realization

摘要

We describe the system presented at the SR' 19 shared task by the DipInfoUnito team. Our approach is based on supervised machine learning. In particular, we divide the SR task into two independent subtasks, namely word order prediction and morphology inflection prediction. Two neural networks with different architectures run on the same input structure, each producing a partial output which is re-combined in the final step in order to produce the predicted surface form. This work is a direct successor of the architecture presented at SR'19.
