EXIST is a series of scientific events and shared tasks on sexism identification in social networks. EXIST aims to capture sexism in a broad sense, from explicit misogyny to other subtle expressions that involve implicit sexist behaviours (EXIST 2021, EXIST 2022). The third and fourth editions of the EXIST shared task was held as a Lab in CLEF 2023. [NEW] Next CLEF 2025 in Madrid, Spain will host the fifth edition of EXIST, including tasks to study sexism characterization in text (microblog posts/tweets), images (memes) and video (TikTok)!

RepLab is a competitive evaluation exercise for Online Reputation Management systems organized as an activity of CLEF for the 2012, 2013, and 2014 editions. RepLab focused on the task of monitoring the reputation of entities (companies, organizations, celebrities, etc.) on Twitter. The monitoring task for analysts consists of searching the stream of tweets for potential mentions to the entity, filtering those that do refer to the entity, detecting topics (i.e., clustering tweets by subject) and ranking them based on the degree to which they signal reputation alerts (i.e., issues that may have a substantial impact on the reputation of the entity).
