Query: Exploring a Unified Sequence-To-Sequence Transformer for Medical Product
  Safety Monitoring in Social Media   Adverse Events (AE) are harmful events resulting from the use of medical
products. Although social media may be crucial for early AE detection, the
sheer scale of this data makes it logistically intractable to analyze using
human agents, with NLP representing the only low-cost and scalable alternative.
In this paper, we frame AE Detection and Extraction as a sequence-to-sequence
problem using the T5 model architecture and achieve strong performance
improvements over competitive baselines on several English benchmarks (F1 =
0.71, 12.7% relative improvement for AE Detection; Strict F1 = 0.713, 12.4%
relative improvement for AE Extraction). Motivated by the strong commonalities
between AE-related tasks, the class imbalance in AE benchmarks and the
linguistic and structural variety typical of social media posts, we propose a
new strategy for multi-task training that accounts, at the same time, for task
and dataset characteristics. Our multi-task approach increases model
robustness, leading to further performance gains. Finally, our framework shows
some language transfer capabilities, obtaining higher performance than
Multilingual BERT in zero-shot learning on French data.
