[Trial]Try the National Library's WriteAid Similarity Scanner System

Overview:
To support students in thesis writing, the National Central Library (NCL) has collaborated with the National Taiwan Normal University team to develop 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by the NCL’s "National Digital Library of Theses and Dissertations in Taiwan," which includes both published and unpublished theses in Chinese and foreign languages.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. Students can download the detection results for their advisors' review.
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 the similarity detection exceeds 50%, the system will treat it as an anomaly. Results will not be immediately available and will be reviewed manually by the National Library before notification is sent.
