Abstract

This paper provides an overview of eRisk 2020, the fourth 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 two tasks. The first task focused on early detecting signs of self-harm. The second task challenged the participants to automatically filling a depression questionnaire based on user interactions in social media.

In the initial configuration, the test period was shorter but, because of the COVID-19 situation, we decided to extend the test stage in order to facilitate participation.

Computed with respect to the positive class.

Observe that Sadeque et al. (see [9], p. 497) computed the latency for all users such that \(g_u=1\). We argue that latency should be computed only for the true positives. The false negatives (\(g_u=1\), \(d_u=0\)) are not detected by the system and, therefore, they would not generate an alert.

Again, we adopt Sadeque et al.’s proposal but we estimate latency only over the true positives.

In the evaluation we set p to 0.0078, a setting obtained from the eRisk 2017 collection.

Actually, slightly less than 25% because a couple of questions have more than four possible answers.
