Checklist ROAI 2025 National Stage · Task 1
Human vs AI
Romanian title: Om vs AI
Detect whether Romanian texts were written by a human or generated by AI, and assign texts to four topics without topic labels.
The task
As AI-generated content spreads, it becomes harder to tell human from machine-written text, while identifying a text's topic remains essential for organising information.
Subtask 1 asks for a binary model (0 = human, 1 = AI) trained on train_data.csv and applied to the test texts marked with subtaskID 1. Subtask 2 asks for the topic of each test text marked with subtaskID 2 among SCIENCE, BUSINESS, CRIME and RELIGION, although the training file contains no topic labels.
Abridged and translated by SOTA from the official Romanian materials. The official statement has the exact rules, and it wins wherever this summary differs.
At a glance
- You get
train_data.csv(ID, text, label 0/1) andtest_data.csv(ID, subtaskID, text).- You submit
output.csvwith subtaskID, datapointID (text ID) and answer (0/1 for subtask 1, topic string for subtask 2).- Scoring
- Subtask 1 (60 points): macro-F1; ≥ 95% gives 60, 70–94.99% gives 10–50 by linear interpolation, below 70% gives 0. Subtask 2 (40 points): accuracy; below 25% gives 5, 25–49.99% gives 5–10, 50–79.99% gives 10–20, 80–96.99% gives 20–35, ≥ 97% gives 40.
