BLEnD: A Benchmark for LLMs on Everyday Knowledge in Diverse Cultures and Languages

NeurIPS 2024poster

Large language models (LLMs) often lack culture-specific everyday knowledge, especially across diverse regions and non-English languages. Existing benchmarks for evaluating LLMs' cultural sensitivities are usually limited to a single language or online sources like Wikipedia, which may not reflect t…

Exploring Cross-Cultural Differences in English Hate Speech Annotations: From Dataset Construction to Analysis

NAACL 2024long

Most hate speech datasets neglect the cultural diversity within a single language, resulting in a critical shortcoming in hate speech detection. To address this, we introduce CREHate, a CRoss-cultural English Hate speech dataset. To construct CREHate, we follow a two-step procedure: 1) cultural post…

Measuring Political Bias in Large Language Models: What Is Said and How It Is Said

ACL 2024long

We propose to measure political bias in LLMs by analyzing both the content and style of their generated content regarding political issues. Existing benchmarks and measures focus on gender and racial biases. However, political bias exists in LLMs and can lead to polarization and other harms in downs…

RHO: Reducing Hallucination in Open-domain Dialogues with Knowledge Grounding

ACL 2023findings

Dialogue systems can leverage large pre-trained language models and knowledge to generate fluent and informative responses. However, these models are still prone to produce hallucinated responses not supported by the input source, which greatly hinders their application. The heterogeneity between ex…

Towards Mitigating LLM Hallucination via Self Reflection

EMNLP 2023long findings

Large language models (LLMs) have shown promise for generative and knowledge-intensive tasks including question-answering (QA) tasks. However, the practical deployment still faces challenges, notably the issue of "hallucination", where models generate plausible-sounding but unfaithful or nonsensical…

Evaluating Parameter Efficient Learning for Generation

EMNLP 2022main

Parameter efficient learning methods (PERMs)have recently gained significant attention asthey provide an efficient way for pre-trainedlanguage models (PLMs) to adapt to a downstream task. However, these conclusions aremostly drawn from in-domain evaluations overthe full training set. In this paper,…

Factuality Enhanced Language Models for Open-Ended Text Generation

NeurIPS 2022accept

Pretrained language models (LMs) are susceptible to generate text with nonfactual information. In this work, we measure and improve the factual accuracy of large-scale LMs for open-ended text generation. We design the FactualityPrompts test set and metrics to measure the factuality of LM generatio…

NeuS: Neutral Multi-News Summarization for Mitigating Framing Bias

NAACL 2022long

Media news framing bias can increase political polarization and undermine civil society. The need for automatic mitigation methods is therefore growing. We propose a new task, a neutral summary generation from multiple news articles of the varying political leaningsto facilitate balanced and unbiase…

On Unifying Misinformation Detection

NAACL 2021long

In this paper, we introduce UnifiedM2, a general-purpose misinformation model that jointly models multiple domains of misinformation with a single, unified setup. The model is trained to handle four tasks: detecting news bias, clickbait, fake news, and verifying rumors. By grouping these tasks toget…
