Multi-Hall-SA: A Cross-lingual Benchmark for Multi-Type Hallucination Detection in Low-Resource South African Languages (2026.findings-eacl)
Copied to clipboard
| Challenge: | Large Language Models generate false or unsupported information, which can be difficult to detect in low-resource languages. |
| Approach: | They propose a cross-lingual benchmark for hallucination detection spanning English and South African languages. |
| Outcome: | The proposed model detects 23.6% fewer hallucinations in South African languages compared to English . human validation confirms the quality and cross-lingual alignment of the model . |

| Challenge: | despite LLMs becoming increasingly multilingual, most studies on detecting and quantifying LLM hallucination are English-centric . |
| Approach: | They train a multilingual hallucination detection model and conduct a large-scale study across 30 languages and 6 open-source LLM families. |
| Outcome: | The proposed model is based on an English-centric model and annotates gold data for five high-resource languages. |

Detecting and Mitigating Hallucinations in Multilingual Summarisation (2023.emnlp-main)
Copied to clipboard
| Challenge: | Existing faithfulness metrics for abstractive summarisation models focus on English . metric mFACT is best suited to detect hallucinations in cross-lingual transfer . |
| Approach: | They propose a method to evaluate the faithfulness of non-English summaries by translation-based transfer from multiple English faithfulness metrics. |
| Outcome: | The proposed method reduces hallucinations in cross-lingual transfer by weighing the loss of each training example by its faithfulness score. |
DiaHalu: A Dialogue-level Hallucination Evaluation Benchmark for Large Language Models (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Existing benchmarks for hallucination detection are intentionally generated by large language models (LLMs) however, many focus on factuality while ignoring faithfulness. |
| Approach: | They propose a dialogue-level hallucination evaluation benchmark for large language models . they integrate the topic into prompts and facilitate a dialog between two LLMs . |
| Outcome: | The proposed benchmark covers four common multi-turn dialogue domains and five hallucination subtypes, extended from factuality and faithfulness hallucines. |
