Second-Order Neural Dependency Parsing with Message Passing and End-to-End Training

2020-10-10 · Asian Chapter of the Association for Computational Linguistics 2020 · Xinyu Wang, Kewei Tu

In this paper, we propose second-order graph-based neural dependency parsing using message passing and end-to-end neural networks. We empirically show that our approaches match the accuracy of very recent state-of-the-art second-order graph-based neural dependency parsers and have significantly faster speed in both training and testing. We also empirically show the advantage of second-order parsing over first-order parsing and observe that the usefulness of the head-selection structured constraint vanishes when using BERT embedding.

Combining (second-order) graph-based and headed-span-based projective dependency parsing

2021-08-12 · Findings (ACL) 2022 5 · Songlin Yang, Kewei Tu

Graph-based methods, which decompose the score of a dependency tree into scores of dependency arcs, are popular in dependency parsing for decades. Recently, \citet{Yang2022Span} propose a headed-span-based method that de…

Second-Order Unsupervised Neural Dependency Parsing

2020-10-28 · COLING 2020 8 · Songlin Yang, Yong Jiang, Wenjuan Han, Kewei Tu

Most of the unsupervised dependency parsers are based on first-order probabilistic generative models that only consider local parent-child information. Inspired by second-order supervised dependency parsing, we proposed …
