Title: Dependency Parsing with Dilated Iterated Graph CNNs,
Abstract: Dependency parses are an effective way to inject linguistic knowledge into
many downstream tasks, and many practitioners wish to efficiently parse
sentences at scale. Recent advances in GPU hardware have enabled neural
networks to achieve significant gains over the previous best models, these
models still fail to leverage GPUs' capability for massive parallelism due to
their requirement of sequential processing of the sentence. In response, we
propose Dilated Iterated Graph Convolutional Neural Networks (DIG-CNNs) for
graph-based dependency parsing, a graph convolutional architecture that allows
for efficient end-to-end GPU parsing. In experiments on the English Penn
TreeBank benchmark, we show that DIG-CNNs perform on par with some of the best
neural network parsers.
