Not another Negation Benchmark: The NaN-NLI Test Suite for Sub-clausal Negation (2022.aacl-main)
Copied to clipboard
| Challenge: | Negation is an important linguistic phenomenon which denotes non-existence, denial, or contradiction. |
| Approach: | They propose a natural language inference test suite to test models for negation . they use a linguistic framework to analyze negation types and constructions . |
| Outcome: | The proposed test suite is more challenging than existing benchmarks on negation . it includes annotation of negation types and constructions grounded in linguistic theory . |
COVID-19 Named Entity Recognition for Vietnamese (2021.naacl-main)
Copied to clipboard
| Challenge: | a new dataset is being developed to help fight the COVID-19 pandemic . the dataset is annotated for the named entity recognition task with newly-defined entity types . |
| Approach: | They present the first manually-annotated COVID-19 domain-specific dataset for Vietnamese . their dataset is annotated for the named entity recognition task with newly-defined entity types . |
| Outcome: | The proposed dataset is the first manually-annotated COVID-19 domain-specific dataset for Vietnamese. |

Yulia Otmakhova, Thinh Hung Truong, Rahmad Mahendra, Zenan Zhai, Rongxin Zhu, Daniel Beck, Jey Han Lau
| Challenge: | FLUKE introduces controlled variations across linguistic levels and leverages large language models with human validation to generate modifications. |
| Approach: | They propose a framework for assessing model robustness through systematic minimal variations of test data. |
| Outcome: | The proposed framework evaluates models and LLMs across six diverse NLP tasks and shows that they are more robust to natural, fluent modifications than base models. |
Language models are not naysayers: an analysis of language models on negation benchmarks (2023.starsem-1)
Copied to clipboard
| Challenge: | Negation has been shown to be a major bottleneck for masked language models, such as BERT, but whether this finding still holds for larger-sized auto-regressive language models has not been studied comprehensively. |
| Approach: | They evaluate the ability of current-generation auto-regressive language models to handle negation using a wide range of benchmarks and models. |
| Outcome: | The proposed models are compared against a wide range of negation benchmarks and show that they are insensitive to negation, inability to capture the lexical semantics of negations, and failure to reason under negation. |

Lucy Lu Wang, Yulia Otmakhova, Jay DeYoung, Thinh Hung Truong, Bailey Kuehl, Erin Bransom, Byron Wallace
| Challenge: | Prior work has shown that models may exploit shortcuts that are difficult to detect using standard n-gram similarity metrics such as ROUGE. |
| Approach: | They propose to use human-assessed summary quality facets and pairwise preferences to improve MDS evaluation methods. |
| Outcome: | The proposed methods improve the quality of literature review summarization models . they use human-assessed summary quality facets and pairwise preferences . |
