[Announcements] Update on Dataset Release and Timeline Adjustment

[LLMs4OL Challenge]

Dear Participants,

I hope this message finds you well.

Here are a few updates regarding the dataset release of the challenge:

1. The task C dataset is released. Please refer to the Taxonomy Learning task page for further information: https://sites.google.com/view/llms4ol2026/taxonomy-task 

2. We are currently slightly behind schedule in releasing the datasets for both Task A and Task B. The preparation process is still ongoing, so please expect a delay of a few more days. In light of this, the deadlines for the upcoming phases will be extended accordingly. Additionally, to enable you to work with larger-scale datasets rather than smaller subsets (e.g., approximately 1k or 2k samples), we are increasing the dataset sizes (e.g., approximately 4k or 5k). This enhancement requires additional time for annotation and preparation.

We appreciate your patience and understanding. In the meantime, if you are participating, please refer to the Google Form for registration (https://forms.gle/2ujAHqYoj8btaHqK6). We require this information for organizational purposes.

If you have any questions, please feel free to reach out to us at llms4ol....@gmail.com

Best regards,
