Dear all,

Thank you again for your interest in our shared task and for the effort you have put into it.

We are pleased to announce that the official test leaderboard is now live on the same competition page. You should now be able to submit your predictions on the test data under the “Official Test Task” phase.

We have also uploaded a baseline submission using Qwen3.5-9B (submission ID #882182), which achieves an F1 score of 0.2964. The validation phase has now been automatically closed.

Please note that you have one week to submit your test predictions. The submission deadline is August 15, 2026.

We hope you enjoy the competition, and good luck with your submissions!

Best regards,
AKBC 2026 Shared Task Organizing Committee
