Towards the Roots of the Negation Problem: A Multilingual NLI Dataset and Model Scaling Analysis

EMNLP 2025

Negations are key to determining sentence meaning, making them essential for logical reasoning. Despite their importance, negations pose a substantial challenge for large language models (LLMs) and remain underexplored.We constructed and published two new textual entailment datasets NoFEVER-ML and N

Concept-aware Data Construction Improves In-context Learning of Language Models

ACL 2024findings

Many recent language models (LMs) are capable of in-context learning (ICL), manifested in the LMs’ ability to perform a new task solely from natural-language instruction. Previous work curating in-context learners assumes that ICL emerges from a vast over-parametrization or the scale of multi-task t…

Soft Alignment Objectives for Robust Adaptation of Language Generation

ACL 2023long

Domain adaptation allows generative language models to address specific flaws caused by the domain shift of their application. However, the traditional adaptation by further training on in-domain data rapidly weakens the model’s ability to generalize to other domains, making the open-ended deploymen…
