CompLx@SMM4H’22: In-domain pretrained language models for detection of adverse drug reaction mentions in English tweets
Orest Xherija | Hojoon Choi
Proceedings of the Seventh Workshop on Social Media Mining for Health Applications, Workshop & Shared Task

The paper describes the system that team CompLx developed for sub-task 1a of the Social Media Mining for Health 2022 (#SMM4H) Shared Task. We finetune a RoBERTa model, a pretrained, transformer-based language model, on a provided dataset to classify English tweets for mentions of Adverse Drug Reactions (ADRs), i.e. negative side effects related to medication intake. With only a simple finetuning, our approach achieves competitive results, significantly outperforming the average score across submitted systems. We make the model checkpoints and code publicly available. We also create a web application to provide a user-friendly, readily accessible interface for anyone interested in exploring the model’s capabilities.
