OVFact: Measuring and Improving Open-Vocabulary Factuality for Long Caption Models (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Large vision-language models struggle to generate long and factual captions . traditional measures for hallucination and factuality are not well suited for longer captions. |
| Approach: | They propose a method for measuring caption factuality of long captions that leverages open-vocabulary visual grounding and tool-based verification without relying on human annotations. |
| Outcome: | The proposed method improves agreement with human judgements and captures both caption descriptiveness and factual precision in the same metric. |
