Millions of users publish contents and interact with one another in a daily fashion. Several studies have shown that the words people use (also in online content) are indicative, through distinctive linguistic patterns, of their psychological state. In 2017, through a fortunate set of events, we started the eRisk project. eRisk, which stands for Early Risk Prediction on the Internet, is concerned with the early detection of signs of psychological problems from users' posts in social media. In this talk  I give an overview of the activities of eRisk as part of CLEF (the Conference and Lab of the Evaluation Forum) over the past few years, with particular attention to the early detection of signs of depression. I also discuss how for depression we passed from the early detection, to the estimation of the level of severity, to the latest task (2023) concerned with estimation of the individual symptoms. I conclude summarising the lessons learned so far and pointing at what might come next, also for other mental disorders. <関連書籍/Related Book> Fabio Crestani, David E. Losada, Javier Parapar (eds.)
