Thesis process


Ouriginal is an online text-matching tool that allows users to identify similarities between documents. The School of Graduate Studies is making this tool available to graduate students and supervisors to foster an awareness of academic integrity and proper research conduct among students, and to ensure that theses and thesis-related documents are compliant with Concordia’s Academic Code of Conduct prior to submission for examination.


If you are using Ouriginal for the first time:

Please request an account by using our webform
If you have an account, log in directly through the Ouriginal website

No. Only graduate students in thesis-based programs are typically eligible to request an Ouriginal account through the Thesis Office. Exceptions may be considered upon email request to; a statement as to why Ouriginal is required must accompany this request. The exception is that students writing major research project documents that are deposited on Spectrum are eligible to obtain Ouriginal accounts via the Thesis Office.

Yes, as a co-author you are permitted to analyze your document using Ouriginal.

No. Only the author can upload unpublished/unsubmitted drafts of a sole-authored work to Ouriginal. However, after a thesis (or thesis-related document) has been formally submitted for examination it may be submitted to Ouriginal by other members of the University (e.g., Examining Committee, GPD, SGS, etc.). A supervisor may upload a student’s unsubmitted thesis draft to Ouriginal if the student grants explicit written permission to the supervisor to do so.

Any written component that is part of a thesis-based graduate program, such as a research proposal document. Other such documents may vary widely from program to program.

By not agreeing to SGS’ Ouriginal terms of use, you relinquish your opportunity to use Ouriginal via the Thesis Office. Even so, following formal submission for examination, your thesis may still be analyzed by other members of the University. Be aware that even if you initially refuse to accept these terms, you may decide to agree to them at a later date in order to get an account.

Yes. Once your thesis is publicly available in Spectrum it can be analyzed by anyone using Ouriginal or other text-matching software.

Please consult Ouriginal Quick Start guide and other instructional resources on the CTL webpage regarding how to interpret an Ouriginal similarity report.

It is important when using Ouriginal to know how to correctly interpret a similarity report. If you are a student, please talk to your supervisor or consult with a Learning Specialist about how to revise your drafts accordingly.

If you suspect research misconduct and/or plagiarism in a formally submitted thesis containing original research, contact the Concordia’s Research Integrity Officer immediately for information on how to proceed. For all other non-thesis related infractions, please contact the Academic Governance Assistant
