This is the abstract for our solution of the National NLP Clinical Challenges (n2c2) track 2. The goal is to identify drugs and drug-related adverse events from the clinical notes. This track includes 9 types of entities and 8 types of relations to be identified. We used two different models to complete the NER tasks and one model for the relation task. We ranked the 8th in the NER task, the 2nd place in the relation task, and the 5th in the end-to-end task.
