In this paper, we provide an overview of the WNUT-2020 shared task on the identification of informative COVID-19 English Tweets.We describe how we construct a corpus of 10K Tweets and organize the development and evaluation phases for this task.In addition, we also present a brief summary of results obtained from the final system evaluation submissions of 55 teams, finding that (i) many systems obtain very high performance, up to 0.91 F 1 score, (ii) the majority of the submissions achieve substantially higher results than the baseline fastText (Joulin et al., 2017), and (iii) fine-tuning pre-trained language models on relevant language data followed by supervised training performs well in this task.
