System Overview
This system is jointly developed by the National Central Library and the technical team of National Taiwan Normal University under the Ministry of Education. Its purpose is to assist graduate students in confirming the originality of their theses and avoiding improper citations or plagiarism. The system primarily compares against the “Taiwan Theses & Dissertations Knowledge Value-Added System,” which covers both published and unpublished theses and dissertations in Taiwan. It supports multiple languages including Chinese and English and serves as an auxiliary management tool for checking domestic theses, available for optional use and not mandatory.
