Overview of eRisk at CLEF 2019: Early Risk Prediction on the Internet (extended overview)

This paper provides an overview of eRisk 2019, the third edition of this lab under the CLEF conference. The main purpose of eRisk is to explore issues of evaluation methodology, effectiveness metrics and other processes related to early risk detection. Early detection technologies can be employed in different areas, particularly those related to health and safety. This edition of eRisk had three tasks. Two of them shared the same format and focused on early detecting signs of depression (T1) or self-harm (T2). The third task (T3) focused on an innovative challenge related to automatically filling a depression questionnaire based on user interactions in social media.
