*** Apologies for multiple posting *** *Information Retrieval from Microblogs during Disasters (IRMiDis)* https://sites.google.com/view/irmidis-fire2022/irmidis Track in conjunction with FIRE 2022 (http://fire.irsi.res.in/fire/2022/home), December 9-13, 2022, Kolkata (Hybrid Event) The IRMiDis track aims to develop datasets and methods for solving various practical research problems associated with a disaster or pandemic situation. The IRMiDis track has been run successfully with FIRE in the years 2017, 2018 and 2021. This year IRMiDis will consist of two important classification tasks over microblogs/tweets associated with the COVID-19 pandemic: (1) classifying tweets according to their vaccine-related sentiment (pro-vaccine, neutral, anti-vaccine) (2) identifying tweets that mention someone experiencing COVID-19 symptoms, which is useful for detecting upcoming surges in COVID cases For both tasks, we will provide training data annotated by human workers, and test data for evaluating the submitted models. *All participating teams will get to publish a working notes paper in the FIRE workshop proceedings. The two best-performing teams in each task will be awarded winner and runner-up certificates, and their names will be put up on the track website.* Training data has already been released. Participating teams need to submit runs by August 1. More details on how to participate are on the IRMiDis site: https://sites.google.com/view/irmidis-fire2022/irmidis.
