Thunder-NUBench introduces rich, manually curated sentence pairs and multiple-choice tasks that contrast standard negation with structurally similar distractors (e.g., local negation, contradiction, paraphrase). The goal is to probe semantic-level understanding of negation.","description_withheld":null,"homepage":"https://huggingface.co/datasets/thunder-research-group/SNU_Thunder-NUBench","introduced_date":"2025-06-17","introduced_date_note":null,"introduced_by":{"paper":"/paper/thunder-nubench-a-benchmark-for-llms-sentence","title":"Thunder-NUBench: A Benchmark for LLMs' Sentence-Level Negation Understanding","first_author":"Yeonkyoung So","url":null},"license":{"name":"CC BY-NC-SA","url":null},"modalities":[{"name":"Texts","url":"/datasets/modality/texts"}],"tasks":[{"name":"Natural Language Understanding","url":"/task/natural-language-understanding","datasets_with_task":"/datasets/task/natural-language-understanding"},{"name":"Negation","url":"/task/negation","datasets_with_task":"/datasets/task/negation"}],"languages":[{"name":"English","url":"/datasets/language/english"}],"variants":["Thunder-NUBench"],"data_loaders":[],"num_papers_in_archive":1,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
