Y2K@SMM4H 2025: MUSIC: A Multilingual Social-Media Interpreter with Self-Correction Ability
SMM4H 2025 Task 1 requires detecting adverse drug‑event (ADE) mentions in social‑media posts of four languages. We introduce MUSIC, a compact two‑stage decoder-only language model to tackle the task. MUSIC combines a Classifier that assigns an initial label with a Judge that confirms or overturns that decision. An ensemble of Classifier and Judge checkpoints achieves a weighted-F1 of 0.7079 on the blind test set, outperforming the task median by 8 percentage points and the mean by 17.
