In response to the large volume of literature published on COVID-19, the computing community has introduced text mining corpora, modeling resources, systems and community-wide shared tasks specific to COVID-19 to address the mounting challenge. Corpora are collections of documents, preprocessed to extract machine-readable text, that are used for text mining; in this case, we focus on corpora-containing scientific articles. Modeling resources can be incorporated by text mining practitioners into production systems and consist of things such as text embeddings, data annotations, pretrained language models, knowledge graphs and more. Systems are applications that incorporate text mining models and user interfaces to provide functionalities such as the ability to search, discover or visualize article content. Shared tasks are community competitions that promote concentrated work on specific scientific problems.
