The annotation study of grammar points for TCSL

Corpus annotation is an important research subject in corpus linguistics, however, annotation research for teaching Chinese as a second language (TCSL) is scarce. It is difficult to retrieve data which are suitable for teaching from the general Chinese corpus. To deal with this problem, firstly, this paper proposed the concept of grammar points annotation and discussed the contents and methods of annotating grammar points in the corpus. Secondly, annotated 121 grammar points in 141464 sentences and got 95592 annotated data with semantic and syntactic information. Finally, this paper introduced the application of annotated data in TCSL.
