BabyLM’s First Constructions: Causal interventions provide a signal of learning

EMNLP 2025

Construction grammar posits that language learners acquire constructions (form-meaning pairings) from the statistics of their environment. Recent work supports this hypothesis by showing sensitivity to constructions in pretrained language models (PLMs), including one recent study (Rozner et al., 202

Constructions Are So Difficult That Even Large Language Models Get Them Right for the Wrong Reasons

COLING 2024main

In this paper, we make a contribution that can be understood from two perspectives: from an NLP perspective, we introduce a small challenge dataset for NLI with large lexical overlap, which minimises the possibility of models discerning entailment solely based on token distinctions, and show that GP…

SynthEval: Hybrid Behavioral Testing of NLP Models with Synthetic CheckLists

EMNLP 2024finding

Traditional benchmarking in NLP typically involves using static, held-out test sets and calculating aggregated statistics based on diverse examples. However, this approach often results in an overestimation of performance and lacks the ability to offer comprehensive, interpretable, and dynamic asses…

UCxn: Typologically Informed Annotation of Constructions Atop Universal Dependencies

COLING 2024main

The Universal Dependencies (UD) project has created an invaluable collection of treebanks with contributions in over 140 languages. However, the UD annotations do not tell the full story. Grammatical constructions that convey meaning through a particular combination of several morphosyntactic elemen…

Verbing Weirds Language (Models): Evaluation of English Zero-Derivation in Five LLMs

COLING 2024main

Lexical-syntactic flexibility, in the form of conversion (or zero-derivation) is a hallmark of English morphology. In conversion, a word with one part of speech is placed in a non-prototypical context, where it is coerced to behave as if it had a different part of speech. However, while this process…

A Crosslingual Investigation of Conceptualization in 1335 Languages

ACL 2023long

Languages differ in how they divide up the world into concepts and words; e.g., in contrast to English, Swahili has a single concept for ‘belly’ and ‘womb’. We investigate these differences in conceptualization across 1,335 languages by aligning concepts in a parallel corpus. To this end, we propose…

Counting the Bugs in ChatGPT's Wugs: A Multilingual Investigation into the Morphological Capabilities of a Large Language Model

EMNLP 2023long main

Large language models (LLMs) have recently reached an impressive level of linguistic capability, prompting comparisons with human language skills. However, there have been relatively few systematic inquiries into the linguistic capabilities of the latest generation of LLMs, and those studies that do…

Crosslingual Transfer Learning for Low-Resource Languages Based on Multilingual Colexification Graphs

EMNLP 2023long findings

In comparative linguistics, colexification refers to the phenomenon of a lexical form conveying two or more distinct meanings. Existing work on colexification patterns relies on annotated word lists, limiting scalability and usefulness in NLP. In contrast, we identify colexification patterns of more…

How to Distill your BERT: An Empirical Study on the Impact of Weight Initialisation and Distillation Objectives

ACL 2023short

Recently, various intermediate layer distillation (ILD) objectives have been shown to improve compression of BERT models via Knowledge Distillation (KD). However, a comprehensive evaluation of the objectives in both task-specific and task-agnostic settings is lacking. To the best of our knowledge, t…

CaMEL: Case Marker Extraction without Labels

ACL 2022long

We introduce CaMEL (Case Marker Extraction without Labels), a novel and challenging task in computational morphology that is especially relevant for low-resource languages. We propose a first model for CaMEL that uses a massively multilingual corpus to extract case markers in 83 languages based only…

The better your Syntax, the better your Semantics? Probing Pretrained Language Models for the English Comparative Correlative

EMNLP 2022main

Construction Grammar (CxG) is a paradigm from cognitive linguistics emphasising the connection between syntax and semantics. Rather than rules that operate on lexical items, it posits constructions as the central building blocks of language, i.e., linguistic units of different granularity that combi…
