Thunder-NUBench: A Benchmark for LLMs’ Sentence-Level Negation Understanding (2026.findings-eacl)
Copied to clipboard
| Challenge: | Negation is a fundamental linguistic phenomenon that poses ongoing challenges for Large Language Models (LLMs) Current benchmarks treat negation as a minor detail within broader tasks, such as natural language inference. |
| Approach: | They propose a novel benchmark specifically created to assess sentence-level understanding of negation in Large Language Models (LLMs). |
| Outcome: | The proposed benchmark compares standard negation with structurally diverse alternatives, such as local negation, contradiction, and paraphrase. |
Beyond Task-Oriented and Chitchat Dialogues: Proactive and Transition-Aware Conversational Agents (2025.emnlp-main)
Copied to clipboard
| Challenge: | Current efforts to bridge the two modes of interaction are reactive, focusing on responding to user inputs rather than coordinating dialogue flows. |
| Approach: | They propose a dataset designed for transition-aware dialogue modeling that incorporates structurally diverse and integrated mode flows. |
| Outcome: | The proposed dataset outperforms baseline models in intent detection and mode transition handling. |
The effects of distance on NPI illusive effects in BERT (2024.emnlp-main)
Copied to clipboard
| Challenge: | Recent studies have examined the syntactic capabilities of pre-trained language models, such as BERT. |
| Approach: | They examine the syntactic capabilities of pre-trained language models by using psycholinguistic stimuli. |
| Outcome: | The proposed model is highly sensitive to hierarchical or linear information compared to hierarical layers . |
Thunder-KoNUBench: A Corpus-Aligned Benchmark for Korean Negation Understanding (2026.findings-acl)
Copied to clipboard
| Challenge: | Negation is a fundamental operation in natural language that reverses the meaning of an expression into its opposite. |
| Approach: | They propose a sentence-level negation understanding benchmark that measures negation performance in Korean. |
| Outcome: | The proposed benchmark improves negation understanding and broader comprehension in Korean. |
