A New Tale of Two C's: CROWN2021 and Upcoming CLOB2021

CROWN2021 is a balanced Brown family American English corpus of one million words published in 2021. It is developed under the leadership of Jiajin Xu and is sampled by Mingchen Sun and 12 other post-graduate students at BFSU. CROWN2021 serves as essential language resources for describing American written English in 2021, and an excellent reference corpus for contrastive studies concerning the diachronic change (e.g. Brown, Frown, Crown), regional variation (e.g. LOB, FLOB, CLOB) and cross-linguistic comparison (e.g. LCMC, ToRCH, GLOBE). Users can get access to the online version of CROWN2021 and other BFSU-built Brown family corpora at BFSU CQPweb Corpus Portal (http://114.251.154.212/cqp/). Both user ID and passcode are "test".
