Applying Occam’s Razor to Transformer-Based Dependency Parsing: What Works, What Doesn’t, and What is Really Necessary

no code implementations ACL (IWPT) 2021 Stefan Grünewald, Annemarie Friedrich, Jonas Kuhn

We find that the choice of pre-trained embeddings has by far the greatest impact on parser performance and identify XLM-R as a robust choice across the languages in our study.

Unifying the Treatment of Preposition-Determiner Contractions in German Universal Dependencies Treebanks

no code implementations UDW (COLING) 2020 Stefan Grünewald, Annemarie Friedrich

HDT-UD, the largest German UD treebank by a large margin, as well as the German-LIT treebank, currently do not analyze preposition-determiner contractions such as zum (= zu dem, “to the”) as multi-word tokens, which is inconsistent both with UD guidelines as well as other German UD corpora (GSD and PUD).

RobertNLP at the IWPT 2021 Shared Task: Simple Enhanced UD Parsing for 17 Languages

no code implementations ACL (IWPT) 2021 Stefan Grünewald, Frederik Tobias Oertel, Annemarie Friedrich

This paper presents our multilingual dependency parsing system as used in the IWPT 2021 Shared Task on Parsing into Enhanced Universal Dependencies.

A Corpus Study of Creating Rule-Based Enhanced Universal Dependencies for German

1 code implementation EMNLP (LAW, DMR) 2021 Teresa Bürkle, Stefan Grünewald, Annemarie Friedrich

In this paper, we present a first attempt at enriching German Universal Dependencies (UD) treebanks with enhanced dependencies.

MuLMS: A Multi-Layer Annotated Text Corpus for Information Extraction in the Materials Science Domain

1 code implementation24 Oct 2023 Timo Pierre Schrader, Matteo Finco, Stefan Grünewald, Felix Hildebrand, Annemarie Friedrich

Keeping track of all relevant recent publications and experimental results for a research area is a challenging task.

Negation-Instance Based Evaluation of End-to-End Negation Resolution

1 code implementation CoNLL (EMNLP) 2021 Elizaveta Sineva, Stefan Grünewald, Annemarie Friedrich, Jonas Kuhn

In this paper, we revisit the task of negation resolution, which includes the subtasks of cue detection (e. g. "not", "never") and scope resolution.

Maximum Spanning Trees Are Invariant to Temperature Scaling in Graph-based Dependency Parsing

no code implementations15 Jun 2021 Stefan Grünewald

Modern graph-based syntactic dependency parsers operate by predicting, for each token within a sentence, a probability distribution over its possible syntactic heads (i. e., all other tokens) and then extracting a maximum spanning tree from the resulting log-probabilities.

Coordinate Constructions in English Enhanced Universal Dependencies: Analysis and Computational Modeling

no code implementations EACL 2021 Stefan Grünewald, Prisca Piccirilli, Annemarie Friedrich

In this paper, we address the representation of coordinate constructions in Enhanced Universal Dependencies (UD), where relevant dependency links are propagated from conjunction heads to other conjuncts.

Generalized chart constraints for efficient PCFG and TAG parsing

no code implementations ACL 2018 Stefan Grünewald, Sophie Henning, Alexander Koller

Chart constraints, which specify at which string positions a constituent may begin or end, have been shown to speed up chart parsers for PCFGs.
