Abstract: The CCKS 2020 Evaluation Task 3 presented clinical named entity recognition and event extraction for the Chinese electronic medical records. Two annotated data sets and some other additional resources for these two subtasks were provided for participators. This evaluation competition attracted 354 teams and 46 of them successfully submitted the valid results. The pretrained language models are widely applied in this evaluation task. Data argumentation and external resources are also helpful.
