Variations in Chinese Vocabulary Networks across Different Proficiency Levels and Their Implications for Teaching Chinese as a Second Language
摘要
Vocabulary acquisition has always been a core issue and challenge in teaching Chinese as a foreign language. This paper constructs a Chinese word-formation complex network based on the syllabus vocabulary of the Chinese Proficiency Grading Standards for International Chinese Language Education and employs the k-core decomposition method to identify a subset of Chinese characters with the robust word-formation capabilities. Using the “proficiency level” from The Chinese Proficiency Grading Standards for International Chinese Language Education as a reference for the learnability of vocabulary and characters, we explore the relationship between characters’ word-formation capabilities and their learnability. We find that the vast majority of characters with robust word-formation capabilities are labeled as lower “proficiency levels,” indicating that these words are easier for learners to master. Previous studies suggest that focusing on high-frequency word-formation components (such as roots in certain languages) facilitates the acquisition of new words. We propose that this complex network-based word-formation analysis method can, under the constraint of limited corpus resources, efficiently identify characters with robust word-formation capabilities. This provides valuable insights for developing vocabulary lists for Chinese language teaching, enabling learners to prioritize easily acquired characters with strong word-formation capabilities, thereby reducing their learning burden.
