The Covid-19 Open Research Dataset (CORD-19) is a growing resource of scientific papers on Covid-19 and related
historical coronavirus research. CORD-19 is designed to facilitate the development of text mining and information
retrieval systems over its rich collection of metadata and structured full text papers. Since its release, CORD-19
has been downloaded over 75K times and has served as the basis of many Covid-19 text mining and discovery systems.
The dataset itself isn't defining a specific task, but there is a Kaggle challenge that define 17 open research
questions to be solved with the dataset:
