Content Differences in Syntactic and Semantic Representation (N19-1)

Copied to clipboard

Challenge: Syntactic analysis plays an important role in semantic parsing, but the nature of this role remains a topic of ongoing debate.
Approach: They propose to use Universal Dependencies and UCCA as test cases to compare syntactic and semantic schemes.
Outcome: The proposed comparison methodology can be used for fine-grained evaluation of UCCA parsing, highlighting both challenges and potential sources for improvement.

Joint Universal Syntactic and Semantic Parsing (2021.tacl-1)

Copied to clipboard

Challenge: Several attempts have been made to jointly parse syntax and semantics, but this trade-off is not well understood.
Approach: They propose multiple model architectures that exploit the rich syntactic and semantic annotations contained in the Universal Decompositional Semantics dataset to obtain state-of-the-art results.
Outcome: The proposed model outperforms existing models in 8 languages and their results are consistent across languages.

Approach: They compare a rule-based converter and a supervised delexicalized parser to map meaning representations from different frameworks.
Outcome: The proposed method yields surprisingly accurate representations close to fully supervised UCCA parser quality.

Parsing All: Syntax and Semantics, Dependencies and Spans (2020.findings-emnlp)

Copied to clipboard

Challenge: Syntactic and semantic structures are key linguistic contextual clues, but few studies have explored how they can be used to improve syntactical parsing.
Approach: They propose a syntactic and semantic parsing model which integrates syntaktic information in the encoder of neural network and benefits from two representation formalisms in a uniform way.
Outcome: The proposed model achieves state-of-the-art or competitive results on both span and dependency representations and on Penn Treebank.
On the Relation between Syntactic Divergence and Zero-Shot Performance (2021.emnlp-main)

Copied to clipboard

Challenge: Recent advances in cross-lingual transfer methods have enabled significant advances in grammatical processing tasks.
Approach: They examine the extent to which syntactic relations are preserved in translation and parsability in a zero-shot setting.
Outcome: The proposed model is based on a translation task in English and a subset of a standard English RE benchmark translated to Russian and Korean.
Multitask Parsing Across Semantic Representations (P18-1)

Copied to clipboard

Challenge: UCCA parsing is a test case for multitask learning, with auxiliary tasks AMR, SDP and Universal Dependencies (UD) . Semantic parsers have arguably yet to reach their full potential due to the limited amount of semantically annotated training data.
Approach: They propose a general transition-based parser that can parse UCCA, AMR, SDP and Universal Dependencies (UD) they use a transition-driven learning architecture and a uniform transition-basic learning architecture to train the parsers.
Outcome: The proposed parser improves UCCA, AMR, SDP and Universal Dependencies (UD) parsing over training in English, German and French.
Comparing learnability of two dependency schemes: ‘semantic’ (UD) and ‘syntactic’ (SUD) (2021.findings-emnlp)

Copied to clipboard

Challenge: Several studies have suggested that choosing syntactic criteria for assigning heads in dependency trees improves the performance of dependency parsers.
Approach: They propose to use syntactic criteria to assign heads to dependency trees to improve the performance of dependency parsers by using a selection of 21 treebanks.
Outcome: The proposed approach favours content words over function words as heads of dependency relations, while the other favours syntactic heads.
On the Continued Value of Universal Dependencies in the Era of Large Language Models (2026.acl-long)

Copied to clipboard

Challenge: a growing belief that explicit linguistic representations are no longer necessary is questioned in large language models . a recent study examines whether and in what ways this cross-lingual syntactic framework can still benefit LLMs .
Approach: They use Universal Dependencies (UD) to examine whether and in what ways it can still benefit LLMs.
Outcome: The proposed model outperforms its syntax-agnostic counterparts in a cross-lingual evaluation task.
Do UD Trees Match Mention Spans in Coreference Annotations? (2021.findings-emnlp)

Copied to clipboard

Challenge: Existing methods to annotate mention spans are based on delimiting token intervals, but there is no syntactic representation of the mention span.
Approach: They propose to integrate coreference annotation with syntactic annotation to make them convergent in the long term.
Outcome: The proposed approach could be advantageous in the long term, the authors argue.
Towards a Unified Taxonomy of Deep Syntactic Relations (2024.lrec-main)

Copied to clipboard

Challenge: Currently, UD is the standard for morphology and surface syntax annotations, but it is only one step towards natural language understanding.
Approach: They propose to use a set of universal semantic role labels for morphology and surface syntax in four Indo-European and one Uralic languages to analyze the data.
Outcome: The proposed set of universal semantic role labels is based on the data from four Indo-European and one Uralic languages.
