Researchers have developed a new layered taxonomy for annotating grammatical errors in Chinese learner writing. This scheme aims to bridge computational Chinese grammatical error correction (CGEC) with pedagogical error analysis by categorizing errors at character, punctuation, and linguistic levels. The taxonomy includes core labels for edit operations, linguistic domains, and parts of speech, with optional extensions for specific Chinese grammatical features. Initial evaluations using the MuCGEC dataset and a consistency study with large language models suggest the layered approach is promising, though further refinement of category boundaries is needed.
