CLEF 2024 Workshop
Grenoble, 9-12 September 2024
Find Out MoreeRisk explores the evaluation methodology, effectiveness metrics and practical applications (particularly those related to health and safety) of early risk detection on the Internet. Early detection technologies can be employed in different areas, particularly those related to health and safety. For instance, early alerts could be sent when a predator starts interacting with a child for sexual purposes, or when a potential offender starts publishing antisocial threats on a blog, forum or social network. Our main goal is to pioneer a new interdisciplinary research area that would be potentially applicable to a wide variety of situations and to many different personal profiles. Examples include potential paedophiles, stalkers, individuals that could fall into the hands of criminal organisations, people with suicidal inclinations, or people susceptible to depression.
This is the fifth year of eRisk and the lab plans to organize three tasks:
This is a continuation of eRisk 2023' Task 1.
The task consists of ranking sentences from a collection of user writings according to their relevance to a depression symptom. The participants will have to provide rankings for the 21 symptoms of depression from the BDI Questionnaire. A sentence will be deemed relevant to a BDI symptom when it conveys information about the user's state concerning the symptom. That is, it may be relevant even when it indicates that the user is ok with the symptom.
We would release a TREC formatted sentence-tagged dataset (based on eRisk past data) together with the BDI questionnaire. Participants would be free to decide on the best strategy to derive queries from describing the BDI symptoms in the questionnaire.
After receiving the runs from the participating teams, we would create the relevance judgements with the help of human assessors using pooling. We will use the resulting qrels to evaluate the systems with classical ranking metrics (e.g. MAP, nDCG, etc.). This new corpus with annotated sentences would be a valuable resource with multiple applications beyond eRisk.
The task is organized into two different stages:
1 Q0 sentence-id-121 0001 10 myGroupNameMyMethodName 1 Q0 sentence-id-234 0002 9.5 myGroupNameMyMethodName 1 Q0 sentence-id-345 0003 9 myGroupNameMyMethodName ... 21 Q0 sentence-id-456 0998 1.25 myGroupNameMyMethodName 21 Q0 sentence-id-242 0999 1 myGroupNameMyMethodName 21 Q0 sentence-id-347 1000 0.9 myGroupNameMyMethodNameThat is, the participants should submit up to 1000 results sorted by estimated relevance for each of the 21 symptoms of the BDI-II questionarie. Each line contains: symptom_number, Q0, sentence-id, position_in_ranking, score, system_name.
The proceedings of the lab will be published in the online CEUR-WS Proceedings and on the conference website.

Important DatesThis is a continuation of eRisk 2018's T2 and 2019's T1 tasks.
The challenge consists in performing a task on early risk detection of anorexia. The challenge consists of sequentially processing pieces of evidence and detect early traces of anorexia as soon as possible. The task is mainly concerned about evaluating Text Mining solutions and, thus, it concentrates on texts written in Social Media. Texts should be processed in the order they were created. In this way, systems that effectively perform this task could be applied to sequentially monitor user interactions in blogs, social networks, or other types of online media.
The test collection for this task has the same format as the collection described in [Losada & Crestani 2016]. The source of data is also the same used for previous eRisks. It is a collection of writings (posts or comments) from a set of Social Media users. There are two categories of users, individuals suffering anorexia and control usuers, and, for each user, the collection contains a sequence of writings (in chronological order).
In 2019, we moved from a chunk-based release of data (used in 2017 and 2018) to a item-by-item release of data. We set up a server that iteratively gives user writings to the participating teams. More information about the server is given here. In 2024, the server will be used to provide the users' writings during the test stage.
The task is organized into two different stages:
Evaluation: The evaluation will take into account not only the correctness of the system's output (i.e. whether or not the user is a pathological gambler) but also the delay taken to emit its decision. To meet this aim, we will consider the ERDE metric proposed in [Losada & Crestani 2016] and other alternative evaluation measures. A full description of the evaluation metrics can be found at 2021's erisk overview.
The proceedings of the lab will be published in the online CEUR-WS Proceedings and on the conference website.
To have access to the collection all participants have to fill, sign and send a user agreement form (follow the instructions provided here). Once you have submitted the signed copyright form, you can proceed to register for the lab at CLEF 2024 Labs Registration site
Important DatesThis is a continuation of 2022 and 2023's Task 3. The task consists of estimating the level of features associated with a diagnosis of eating disorders from a thread of user submissions. For each user, the participants will be given a history of postings and the participants will have to fill a standard eating disorder questionnaire (based on the evidence found in the history of postings).
The questionnaires are defined from Eating Disorder Examination Questionnaire (EDE-Q) is a 28-item self-reported questionnaire adapted from the semi-structured interview Eating Disorder Examination (EDE). We will only use questions 1-12 and 19-28. It is designed to assess the range and severity of features associated with a diagnosis of eating disorder using 4 subscales (Restraint, Eating Concern, Shape Concern and Weight Concern) and a global score:

This task aims therefore at exploring the viability of automatically estimating the severity of multiple symptoms associated with eating disorders. Given the user's history of writings, the algorithms have to estimate the user's response to each individual question. We collected questionnaires filled by Social Media users together with their history of writings (we extracted each history of writings right after the user provided us with the filled questionnaire). The questionnaires filled by the users (ground truth) will be used to assess the quality of the responses provided by the participating systems.
The participants will be given a dataset with multiple users (for each user, its history of writings is provided) and they will be asked to produce a file with the following structure:
username1 answer1 answer2 .... answer28 username2 .... ....
Each line has the username and 22 values. These values correspond with the responses to the questions above (the possible values are 0,1,2,3,4,5,6).
The task is organized into two different stages:
Evaluation: The evaluation will take into the answers to the questionnaire from the systems and the actual response from the users. A full description of the evaluation metrics can be found at 2022's erisk overview.
