Agenda

9:00 — Welcome

Presenter: Duc Tien Dang Nguyen

9:00 – 9:20 AM — Invited Talk (Zoom)

Speaker: Hendrik B. Vold, an Associate Director with the Norwegian Institute of Journalism. Vold teaches applied generative AI for journalism, but his heart is really in OSINT and combatting disinformation. He has worked with developing a workflow for fast verification of media content aimed at providing trusted information for newsrooms, and he has run workshops nationally and globally for investigative journalists. Vold will be talking about his experiences when assessing new LLM workflows for automated verification.

9:20 – 9:30 AM — Grand Challenge Overview

9:30 – 10:00 AM — Team Presentations

(10 minutes per team, no individual Q&A)

Please focus on what you did and what you learned — real lessons from the approach.

Skip introductions to the problem or general background; attendees are already familiar with the challenge.

Each team should:

  • Present the proposed method clearly and concisely.
  • Include two–three representative example cases (training, validation, or final).
  • Highlight key findings, insights, and takeaways.
