Abstract
In 2017, we launched eRisk as a CLEF Lab to encourage research on early risk detection on the Internet. The eRisk 2021 was the fifth edition of the Lab. Since then, we have created a large number of collections for early detection addressing different problems (e.g., depression, anorexia or self-harm). This paper outlines the work that we have done to date (2017, 2018, 2019, 2020, and 2021), discusses key lessons learned in previous editions, and presents our plans for eRisk 2022, which introduces a new challenge to assess the severity of eating disorders.
