Screening for duplicate text in PhD thesis
The Faculty of Health and Medical Sciences screens all PhD theses for duplicate text immediately after submission and prior to forwarding to assessment committees. If no duplicate text is identified, the screening takes a maximum of seven days. The Royal Library conducts the screening using the detection software iThenticate. It is not possible for PhD students to conduct this screening in advance.
Overview of the screening process
- Plagiarism is considered research misconduct
- Self-plagiarism is regarded as questionable research practice.
Self-plagiarism is categorised as the duplication of text without correct references from the PhD student’s own work. This includes master theses as well as published articles and manuscripts for which the PhD student is an author or co-author.
PlagiarismWhen plagiarism is suspected in a PhD thesis, the University of Copenhagen Practice Committee and the Danish Committee on Research Misconduct investigate the scope and nature of the duplicate text.
The ruling from the Danish Committee on Research Misconduct must be presented before the thesis is submitted for assessment. If the Committee finds the duplicate text to be plagiarism, the thesis is rejected with no further opportunity for revision.
Self-plagiarismIn most cases of suspected self-plagiarism, the PhD student and their principal supervisor are summoned for a meeting at the Graduate School to discuss revisions of the thesis before it is submitted for assessment. The Practice Committee may also investigate the matter.
For questions on text duplication, please speak to your principal supervisor. For additional guidance, contact the Graduate School.
