Abstract of "Constructing and researching the Spoken and Written English Corpus of Chinese Learners (2007)"
This paper describes the Project of Spoken and Written English Corpus of Chinese Learners (SWECCL) co-constructed by Nanjing University and the Foreign Language Teaching and Research Press. It also reviews some of the recent SWECCL-based studies on the Chinese EFL learners' interlanguage by the project team. It points out that learner corpus-based research is a new direction in the studies of second language acquisition.
The rest is in Chinese.
Here's a quote from Lee & Chen's (2009)Making a bigger deal of the smaller words: Function words and other key items in research writing by Chinese learners which seems to refer to version 1.0:
Spoken and Written English Corpus of Chinese Learners (SWECCL; Wen, Wang, & Liang, 2005), a major corpus project covering university English major students in China, contains only timed argumentative essays written for proficiency exams, ignoring dissertations and other academic genres.
So far this is all I can find.
