Plagiarism review using Ouriginal
Ouriginal is a tool used for plagiarism review of assignments and should be used by teachers and examiners when students submit text files in Canvas. Ouriginal can also be used independently from Canvas. A good way to counter plagiarism is to raise the issue with your students and contribute to their knowledge of how to make references correctly.
Ouriginal reviews, the teacher decides
Ouriginal produces potential matching sources from three archives:
- Sources from the Internet.
- Academically published material.
- Previously submitted student documents.
When Ouriginal searches for and records the degree of matching, it also consider all uses of rephrasing, synonyms and other forms of substitution. Ouriginal will therefore not be fooled by e.g. write about 'I bought milk' to 'lactose drink was bought by me'. It is you as a teacher who must actively take a stand on the reports that Ouriginal provides.
Always look through the entire report
The report from Ouriginal is just a tool, however. A high or low match does not determine anything; it is the teacher who is responsible to review the report from Ouriginal and decide if it is plagiarism or not. In cases where the student has tried to deceive Ouriginal with documents that look good to humans but are unreadable to computers, Ouriginal will mark it as misspelt. Always look through the entire report and review what has been found. Also make sure you manually review the document and look for both differences in document layout and language as well as the document’s editing history. More information of what to manually look for can be found in the KTH Handbook:
(Please note that the English version of the Handbook starts on page 86)
Which documents can/are eligible to be reviewed?
Only documents produced since KTH has had Ouriginal (2017 and onwards) may be reviewed. Note that the documents must be relevant to the course or education.
Ouriginal does not process documents containing less than 430 characters and 20 words. If a student has submitted a document that is too small in a Canvas assignment linked to Ouriginal, the student will receive an email from Ouriginal with information that the document has not been forwarded to the recipient. Teachers, however, see the student's submission as usual in Canvas but with information that Ouriginal is still working on the assignment. Since Ouriginal will not review the submission, it will never be marked as finished in Canvas. Also, if a file of non-supported format is submitted an exclamation mark will be shown in Canvas for the submission.
If you discover possible plagiarism (text-matching) in an assignment that Ouriginal has reviewed or has been reviewed manually you need to assess whether it may be an attempt of misleading during examination. There is a designated contact person at each school to assist in plagiarism cases and similar disciplinary offenses.
Guide your students away from plagiarism
It is always better to get students to avoid plagiarism than to punish those who plagiarize, especially since many students do not know what plagiarism is in practice.
Tell your students what plagiarism is and what the consequences may be. Feel free to share the page Cheating and plagiarism with your students so they can read about how they can avoid it.
