The Shape of Adversarial Influence: Characterizing LLM Latent Spaces with Persistent Homology

ICLR 2026oral

Existing interpretability methods for Large Language Models (LLMs) often fall short by focusing on linear directions or isolated features, overlooking the high-dimensional, nonlinear, and relational geometry within model representations. This study focuses on how adversarial inputs systematically af…

Definition Generation for Word Meaning Modeling: Monolingual, Multilingual, and Cross-Lingual Perspectives

EMNLP 2025

The task of Definition Generation has recently gained attention as an interpretable approach to modeling word meaning. Thus far, most research has been conducted in English, with limited work and resources for other languages. In this work, we expand Definition Generation beyond English to a suite o

LSC-Eval: A General Framework to Evaluate Methods for Assessing Dimensions of Lexical Semantic Change Using LLM-Generated Synthetic Data

ACL 2025finding

Lexical Semantic Change (LSC) provides insight into cultural and social dynamics. Yet, the validity of methods for measuring different kinds of LSC remains unestablished due to the absence of historical benchmark datasets. To address this gap, we propose LSC-Eval, a novel three-stage general-purpose…

Multilinguality Does not Make Sense: Investigating Factors Behind Zero-Shot Cross-Lingual Transfer in Sense-Aware Tasks

EMNLP 2025

Cross-lingual transfer allows models to perform tasks in languages unseen during training and is often assumed to benefit from increased multilinguality. In this work, we challenge this assumption in the context of two underexplored, sense-aware tasks: polysemy disambiguation and lexical semantic ch

Analyzing Semantic Change through Lexical Replacements

ACL 2024long

Modern language models are capable of contextualizing words based on their surrounding context. However, this capability is often compromised due to semantic change that leads to words being used in new, unexpected contexts not encountered during pre-training. In this paper, we model semantic change…

Atomic Inference for NLI with Generated Facts as Atoms

EMNLP 2024main

With recent advances, neural models can achieve human-level performance on various natural language tasks. However, there are no guarantees that any explanations from these models are faithful, i.e. that they reflect the inner workings of the model. Atomic inference overcomes this issue, providing i…

Strengthening the WiC: New Polysemy Dataset in Hindi and Lack of Cross Lingual Transfer

COLING 2024main

This study addresses the critical issue of Natural Language Processing in low-resource languages such as Hindi, which, despite having substantial number of speakers, is limited in linguistic resources. The paper focuses on Word Sense Disambiguation, a fundamental NLP task that deals with polysemous…

Logical Reasoning with Span-Level Predictions for Interpretable and Robust NLI Models

EMNLP 2022main

Current Natural Language Inference (NLI) models achieve impressive results, sometimes outperforming humans when evaluating on in-distribution test sets. However, as these models are known to learn from annotation artefacts and dataset biases, it is unclear to what extent the models are learning the…

DWUG: A large Resource of Diachronic Word Usage Graphs in Four Languages

EMNLP 2021main

Word meaning is notoriously difficult to capture, both synchronically and diachronically. In this paper, we describe the creation of the largest resource of graded contextualized, diachronic word meaning annotation in four different languages, based on 100,000 human semantic proximity judgments. We…
