Unsupervised Dependency Parsing

Description from the archive archive 2025-07-28.

Benchmarks archive 2025-07-28

1 leaderboard table shown for this task, 1 with rows (a “benchmark” on this site is a table with at least one row, as on /sota), ordered by row count. “Best model” is the first row in the archive's own order at snapshot; nothing is re-ranked here and metric direction is not recorded in the archive. PwC's Trend sparklines are not in the archive, so that column is omitted.

Syntology column: samples harvested from the paper's repositories and executed on synthesized fixtures; “ran” is not a correctness claim and does not order the table. A dash means no Syntology record for that paper, not a recorded non-run. Read from the graph 2026-09-24.

Libraries

Not in the archive: the export carries no per-task library table, so there is nothing to show at snapshot 2025-07-28.

Most implemented papers archive 2025-07-28

5 shown of 5 papers with code (24 tagged with this task in all), ordered by repositories listed in the archive, not by stars (the archive holds no stars, so PwC's “Social” and “Latest” sorts cannot be reproduced). Papers without a page here are shown as plain text.

• StructFormer: Joint Unsupervised Induction of Dependency and Constituency Structure from Masked Language Modeling
  1 Dec 2020 2 repositories listed
  There are two major classes of natural language grammar -- the dependency grammar that models one-to-one correspondences between words and the constituency grammar that models the assembly of one or several corresponded…
• Error Diversity Matters: An Error-Resistant Ensemble Method for Unsupervised Dependency Parsing
  16 Dec 2024 1 repository listed
  We address unsupervised dependency parsing by building an ensemble of diverse existing models through post hoc aggregation of their output dependency parse structures.
• Unsupervised Dependency Graph Network
  1 May 2022 1 repository listed
  We introduce a new model, the Unsupervised Dependency Graph Network (UDGN), that can induce dependency structures from raw corpora and the masked language modeling task.
• Unsupervised Learning of Syntactic Structure with Invertible Neural Projections
  28 Aug 2018 1 repository listed
  In this work, we propose a novel generative model that jointly learns discrete syntactic structure and continuous word representations in an unsupervised fashion by cascading an invertible neural network with a…
• CRF Autoencoder for Unsupervised Dependency Parsing
  3 Aug 2017 1 repository listed
  The encoder part of our model is discriminative and globally normalized which allows us to use rich features as well as universal linguistic priors.
