The Corpus of Contemporary American English (COCA) is the most
widely-used corpus in the world. In March 2020 it was updated for
the last time (with data up through Dec 2019), and the collocates data from the corpus was updated in April 2020. The
following are the major changes and improvements in the collocates data.
||More than twice
as large, at one billion words
Corpus: how up to date
from 1990 - ~2012
||The most recent
texts are from Dec 2019. There are 20 million
words each year from 1990-2019 (+ about 240 million words
from blogs and other websites from 2013). So there are about
600 million new words of data since the
previous data was released in 2012.
Spoken, fiction, magazine, newspaper, academic.
||Same five genres
as before (with about 120-130 million words per genre), plus
the three new genres:
-- Blog posts and other web pages
(120-130 million words for each of these two genres). So
much of what we consume nowadays comes from the web, and
these genres include many words that don't occur much
elsewhere (e.g. ebook, webpage, browsing, password,
template, meme, snarky, off-topic, downloadable,
open-source, updated, (to) monetize, upgrade, debunk,
archive, pirate, upgrade).
-- TV and movies subtitles (130 million
words). This is by far the most informal language we've ever
had in COCA. Many studies (e.g.
C show that the data from subtitles
agrees with native speaker intuitions about their language even
better than the data from actual everyday conversation (like in
the BNC). Until now, COCA didn't really have this highly
4.3 million node / collocates pairs for the top 60,000
13.5 million node
/ collocates pairs for the top 60,000 lemmas. Because the
new corpus is much larger, there are many more node /
collocate pairs with the minimum frequency, especially for
