They are hard to use because the format records glyphs and their positions rather than logical structure or reading order. Open-source extractors tend to produce noisy output, and strong proprietary VLMs are expensive… 2. **[Piecing It All Together: Verifying Multi-Hop Multimodal Claims](https://md.research.elamur.ai/free/en/papers/wang-2025-piecing-it-all-together-verifying/)** *(2025 · 8 citations)* The paper addresses a gap in fact-checking research. Existing benchmarks either handle multimodal claims or multi-step textual reasoning, but none require both together. The authors define a new task, multi-hop multimodal claim verification. A system must combine several pieces of evidence from text, images and… ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[2 OLMo 2 Furious ↗](https://arxiv.org/abs/2501.00656) arXiv:2501.00656 · no summary yet**Team OLMo et al.*2025 · 262 citations* 2.
