A survey of syntactic-semantic parsing based on constituent and dependency structures

MS Zhang - Science China Technological Sciences, 2020 - Springer
Syntactic and semantic parsing has been investigated for decades, which is one primary
topic in the natural language processing community. This article aims for a brief survey on …

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 …

Straight to the tree: Constituency parsing with neural syntactic distance

Y Shen, Z Lin, AP Jacob, A Sordoni, A Courville… - arxiv preprint arxiv …, 2018 - arxiv.org
In this work, we propose a novel constituency parsing scheme. The model predicts a vector
of real-valued scalars, named syntactic distances, for each split position in the input …

Cross-lingual RST discourse parsing

C Braud, M Coavoux, A Søgaard - arxiv preprint arxiv:1701.02946, 2017 - arxiv.org
Discourse parsing is an integral part of understanding information flow and argumentative
structure in documents. Most previous research has focused on inducing and evaluating …

Reproducibility in computational linguistics: Are we willing to share?

M Wieling, J Rawee, G van Noord - Computational Linguistics, 2018 - direct.mit.edu
This study focuses on an essential precondition for reproducibility in computational
linguistics: the willingness of authors to share relevant source code and data. Ten years after …

Policy gradient as a proxy for dynamic oracles in constituency parsing

D Fried, D Klein - arxiv preprint arxiv:1806.03290, 2018 - arxiv.org
Dynamic oracles provide strong supervision for training constituency parsers with
exploration, but must be custom defined for a given parser's transition system. We explore …

Sequence labeling parsing by learning across representations

M Strzyz, D Vilares, C Gómez-Rodríguez - arxiv preprint arxiv:1907.01339, 2019 - arxiv.org
We use parsing as sequence labeling as a common framework to learn across constituency
and dependency syntactic abstractions. To do so, we cast the problem as multitask learning …

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 …

Two local models for neural constituent parsing

Z Teng, Y Zhang - arxiv preprint arxiv:1808.04850, 2018 - arxiv.org
Non-local features have been exploited by syntactic parsers for capturing dependencies
between sub output structures. Such features have been a key to the success of state-of-the …

Discontinuous constituency parsing with a stack-free transition system and a dynamic oracle

M Coavoux, SB Cohen - arxiv preprint arxiv:1904.00615, 2019 - arxiv.org
We introduce a novel transition system for discontinuous constituency parsing. Instead of
storing subtrees in a stack--ie a data structure with linear-time sequential access--the …
