Design and analysis of a large-scale COVID-19 tweets dataset. The dataset is introduced in the paper " Twitter conversations predict the daily confirmed COVID-19 cases".

We also release a million-scale COVID-19-specific geotagged tweets dataset - MegaGeoCOV (on GitHub).

BillionCOV will receive quarterly updates, while this dataset ( COV19Tweets) will continue to receive updates every day. If we avoid hydrating those tweet identifiers alone, it saves almost two months in a single hydration task. We re-hydrated the tweets present in this dataset ( COV19Tweets) and found that more than 500 million tweet identifiers point to either deleted or protected tweets. Hydration takes time due to limits placed by Twitter on its tweet lookup endpoint.

We have released BillionCOV- a billion-scale COVID-19 tweets dataset for efficient hydration.

The dataset is introduced in the paper " A Twitter narrative of the COVID-19 pandemic in Australia".

MegaGeoCOV Extended- an extended version of MegaGeoCOV has been released.

For detailed instructions on the hydration of tweet IDs, please read this article. You need to hydrate the tweet IDs in order to get complete data. Twitter's policy restricts the sharing of Twitter data other than IDs therefore, only the tweet IDs are released through this dataset. The real-time Twitter feed is monitored for coronavirus-related tweets using 90+ different keywords and hashtags that are commonly used while referencing the pandemic. The oldest tweets in this dataset date back to October 01, 2019. This dataset has been wholly re-designed on March 20, 2020, to comply with the content redistribution policy set by Twitter. This dataset ( COV19Tweets) includes CSV files that contain IDs and sentiment scores of the tweets related to the COVID-19 pandemic.
