Duan Yucai's Shuowen Jiezi Zhu(Annotations on Shuowen Jiezi) stands as the pinnacle of research on Shuowen Jiezi, centrally reflecting the academic achievements of the Qian-Jia School. Currently, digitalization efforts for this work have largely remained at the textualization stage, with limited progress in the in-depth exploration and systematic presentation of its knowledge system. This research constructs a knowledge base using this work and its draft manuscript Shuowen Jiezi Du(Reading Notes on Shuowen Jiezi) as foundational texts. It designs a three-tier classification system encompassing five major knowledge categories, ten knowledge sets, and fifty-six knowledge points, completing the annotation and structured representation of tens of thousands of knowledge instances. An interactive platform featuring original text retrieval, knowledge navigation, and annotation management functions has been developed. This study represents a systematic practice of digital humanities methods in the field of traditional philology,providing crucial references for the in-depth digitization of ancient texts and the innovation of humanistic research paradigms.
