The Coronavirus Corpus is composed of million words of data, and is updated each day.
As an example of how the corpus is growing, there are 11,706,746 new words of text from the
last week (21-02-19 through 21-02-25).
The Coronavirus Corpus contains a subset of the NOW Corpus. The new articles in the NOW Corpus (about 10,000 articles each day) come from links harvested from hourly Bing News searches, as well as searching 1,000+ websites to find articles that have appeared in the previous 24 hours. We then download the texts, clean them up with JusText (to remove boilerplate material); tag and lemmatize them; and then integrate them into our existing relational database architecture. As mentioned, the Coronavirus Corpus is a subset of the NOW Corpus -- articles dealing in some way with the coronavirus. There are two methods to find these articles: 1. Articles that have at least two
occurrences of the words { coronavirus, COVID, or COVID-19 }. The following
are the number of words, texts, and distinct websites for each 10 day period
since 1 Feb 2020 (as well as all of Jan 2020), e.g. 20-04-11 = 20-04-11 through
