Abstract

We present a simple and effective approach to incorporating syntactic structure into neural attention-based encoderdecoder models for machine translation.We rely on graph-convolutional networks (GCNs), a recent class of neural networks developed for modeling graph-structured data.Our GCNs use predicted syntactic dependency trees of source sentences to produce representations of words (i.e.hidden states of the encoder) that are sensitive to their syntactic neighborhoods.GCNs take word representations as input and produce word representations as output, so they can easily be incorporated as layers into standard encoders (e.g., on top of bidirectional RNNs or convolutional neural networks).We evaluate their effectiveness with English-German and English-Czech translation experiments for different types of encoders and observe substantial improvements over their syntax-agnostic versions in all the considered setups.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
