Astudyonthe Developmentof Complexityand Accuracyof Written Chineseof Korean Learners

This paper collected and compiled Chinese writing corpora of Korean learners of different levels in HSK Dynamic Composition Corpus of Beijing Language and Culture University.Firstly,a series of indicators for measuring the complexity and accuracy of written Chinese were defined.Then,the segmentation,T-unit segmentation,and language phenomenon labeling were applied to compositional corpus,and then the data of each index was used to observe and analyze these writing materials horizontally and vertically.The study found that the indicator of the relative ratio between the category symbol and the number of symbols showed a slow-growth trend,indicating that the vocabulary diversity slowly increased with the level of the composition.In terms of the percentage of vocabulary at each level,the proportion of basic vocabulary showed a downward trend,and the proportion of middle and high level vocabulary generally showed an upward trend.However,the internal B,C,and D vocabularies showed fluctuations and inconsistencies.The complex changes showed that with the increase of Korean Chinese learners' writing level,the vocabulary difficulty in the composition would also increase in the fluctuation.The accuracy of the development of Chinese characters,vocabulary,and syntax in the five levels of Korean learners' written language was non-linear.There were more errors in Chinese characters and vocabulary in the written language of each level group.The percentage of syntactic and error-free T units will improve as the level of composition increases.In addition,this article explored the interactions between the internal indicators of complexity and accuracy.Based on the research results,this paper proposed relevant suggestions for the teaching and acquisition of written Chinese of Korean Chinese learners.It is hoped that this research can play a complementary role in this area.
