| Challenge: | Existing methods to measure image common sense inconsistentness are difficult to implement because of their complexity. |
| Approach: | They propose a visual commonsense model that leverages large vision-language models to extract atomic facts from images and a compact attention-pooling classifier to fine-tune it over encoded atomic fact. |
| Outcome: | The proposed method outperforms existing methods on the WHOOPS! and WEIRD datasets while maintaining a compact attention-pooling classifier over encoded atomic facts. |

| Challenge: | Existing hallucination detection benchmarks operate at the sequence level and are limited to English . Existing methods lacking fine-grained, multilingual supervision are limited in English based on the sequence . |
| Approach: | They propose a large-scale, multilingual dataset annotated with span-level hallucinations across 14 languages. |
| Outcome: | The proposed dataset annotated with span-level hallucinations across 14 languages is scalable and cost-efficient. |
