- for parts involving literature viewpoints, questionnaire items and method descriptions, do not change the original meaning just to reduce the repetition rate.
- AIGC detection also has the possibility of misjudgment.
- The official states that its accuracy and misjudgment rate are at an excellent level in the industry, but no specific values are given.
- Do not take a single result as a conclusion.
- Before submitting for external review or defense, you must take the results of the system finally used by your school as the standard.
