Use the National Central Library’s WriteAid Similarity Scanner System for a Chance to Win a NT$500 Gift Voucher!

Overview:
To support students in thesis writing, the National Central Library (NCL) develops the "WriteAid Similarity Scanner System." This system offers a tool for students to assess the similarity of their thesis content. 

The system compares thesis content against electronic theses collected by the NCL’s "National Digital Library of Theses and Dissertations in Taiwan," which includes both published and unpublished theses in Chinese and foreign languages. Note that charts and graphs are not included in the comparison scope. This system offers a different scope of comparison compared to Turnitin Feedback Studio. Using both systems can help students more comprehensively detect thesis similarity.

Restrictions:

1. The National Library only provides access to "graduating master’s and doctoral students" and does not offer access to advisors. However, once a student completes a similarity check, both the student and the advisor will receive a notification email with a link to view the similarity report.
2. Each student is allowed up to 5 detections. The first 3 detections have no time limit (approximately within 30 minutes). The 4th and 5th detections require a 24-hour waiting period for results.
3. If a submission is found to have abnormally high similarity, the system will suspend related operations for that file, and still count it as one of the 5 detections. Results will not be immediately available and will be reviewed manually by the NCL before notification is sent.
4. For system usage issues, please contact the NCL and fill out their Customer Service Form.
