Constituency parsing with a self-attentive encoder

N Kitaev, D Klein - arxiv preprint arxiv:1805.01052, 2018 - arxiv.org
We demonstrate that replacing an LSTM encoder with a self-attentive architecture can lead
to improvements to a state-of-the-art discriminative constituency parser. The use of attention …

Multilingual constituency parsing with self-attention and pre-training

N Kitaev, S Cao, D Klein - arxiv preprint arxiv:1812.11760, 2018 - arxiv.org
We show that constituency parsing benefits from unsupervised pre-training across a variety
of languages and a range of pre-training conditions. We first compare the benefits of no pre …

A minimal span-based neural constituency parser

M Stern, J Andreas, D Klein - arxiv preprint arxiv:1705.03919, 2017 - arxiv.org
In this work, we present a minimal neural model for constituency parsing based on
independent scoring of labels and spans. We show that this model is not only compatible …

Improved transition-based parsing by modeling characters instead of words with LSTMs

M Ballesteros, C Dyer, NA Smith - arxiv preprint arxiv:1508.00657, 2015 - arxiv.org
We present extensions to a continuous-state dependency parsing method that makes it
applicable to morphologically rich languages. Starting with a high-performance transition …

[PDF][PDF] It depends: Dependency parser comparison using a web-based evaluation tool

JD Choi, J Tetreault, A Stent - … of the 53rd Annual Meeting of the …, 2015 - aclanthology.org
The last few years have seen a surge in the number of accurate, fast, publicly available
dependency parsers. At the same time, the use of dependency parsing in NLP applications …

Neural CRF parsing

G Durrett, D Klein - arxiv preprint arxiv:1507.03641, 2015 - arxiv.org
This paper describes a parsing model that combines the exact dynamic programming of
CRF parsing with the rich nonlinear featurization of neural net approaches. Our model is …

Span-based constituency parsing with a structure-label system and provably optimal dynamic oracles

J Cross, L Huang - arxiv preprint arxiv:1612.06475, 2016 - arxiv.org
Parsing accuracy using efficient greedy transition systems has improved dramatically in
recent years thanks to neural networks. Despite striking results in dependency parsing …

Parsing as reduction

D Fernández-González, AFT Martins - arxiv preprint arxiv:1503.00030, 2015 - arxiv.org
We reduce phrase-representation parsing to dependency parsing. Our reduction is
grounded on a new intermediate representation," head-ordered dependency trees", shown …

[PDF][PDF] Domain adaptation for dependency parsing via self-training

J Yu, M El-karef, B Bohnet - Proceedings of the 14th International …, 2015 - aclanthology.org
This paper presents a successful approach for domain adaptation of a dependency parser
via self-training. We improve parsing accuracy for out-of-domain texts with a self-training …

Better, faster, stronger sequence tagging constituent parsers

D Vilares, M Abdou, A Søgaard - arxiv preprint arxiv:1902.10985, 2019 - arxiv.org
Sequence tagging models for constituent parsing are faster, but less accurate than other
types of parsers. In this work, we address the following weaknesses of such constituent …
