? This project is one of the sub-projects of the integrated research project "Research on the Indicators for the Classification of Chinese Language Learning in Primary and Secondary Schools". The goal of this integrated project is to build a corpus of textbooks and reference readings for primary and secondary school students, and to understand the current status of each learning status, and to provide reference of the characters, words, and sentence patterns of each learning stage according to the statistcal information such as frequency and corpus coverage and the suggestions of experts and scholars.
? The tenth sub-project will be responsible for constructing the high school text corpus required by the sub-projects seven to nine, and will provide analysis and statistical reference information for the construction of characters and words to be more objective and scientific in formulating the standards of characters and words at each learning stage for subsequent Curriculum Guidelines development and textbook writing reference. On the other hand, based on the research results of sub-projects 2-9, cross-domain and cross-curricular analysis will be carried out to compare the gaps in the Chinese characters, words and sentence patterns used in each learning stage and the cohesion problems of the stages. The project will mainly adopt the methods of system implementation, document analysis and expert consultation.
