Plagiarism Detection

Plagiarism Detection Tool

The University’s plagiarism detection tool is an efficient way to identify common writing issues and deter plagiarism in course assignments. Instructors using this tool can create an assignment in their Quercus course to which students submit their assignments electronically for analysis.

With the integration of the University’s plagiarism detection tool into Quercus courses, instructors and students should not access the program through the company’s website. 

Each submitted paper is checked for textual similarity using millions of resources stored in the company’s database. Instructors can access and view the Similarity Report in their Quercus course. The University’s plagiarism detection tool can help students develop their writing skills, save instructors time in the investigation of the similarity of student work, and allow for efficient citation verification. Using this information, as well as any other relevant information, it is then up to the individual instructor to determine if these passages represent plagiarism. Before using University’s plagiarism detection tool instructors must adhere to U of T’s Conditions of Use.

Similarity Reports highlight suspicious passages and do not make judgments as to whether a paper has been plagiarized. Users may use the report’s information, as well as any other relevant information, to determine if these passages represent plagiarism.

Conditions of Use at the University of Toronto

The use of the University’s plagiarism detection tool by our instructors is completely voluntary. Those wishing to use this tool in their courses must adhere to the following conditions of use:

  1. The University’s plagiarism detection tool is a tool that will assist in detecting textual similarities between compared works. Instructors must exercise their independent professional judgment in, and assume responsibility for, determining whether a text has been plagiarized or not.
  2. Instructors must include the following passage (as is) on the course outline at the start of the class. Please note that the statement cannot be altered in any way.
    “Normally, students will be required to submit their course essays to the University’s plagiarism detection tool for a review of textual similarity and detection of possible plagiarism. In doing so, students will allow their essays to be included as source documents in the tool’s reference database, where they will be used solely for the purpose of detecting plagiarism. The terms that apply to the University’s use of this tool are described on the Centre for Teaching Support & Innovation web site (https://uoft.me/pdt-faq).”
  3. Students are permitted, under our conditions of use, to opt-out of using the University’s plagiarism detection tool. If a student chooses not to submit their assignment through the plagiarism detection tool, instructors will need to find alternative arrangements to check their work as rigorously. (It should be noted that very few students choose to opt out.) Students cannot be penalized for choosing to opt out. If students choose to opt out, they should let their instructor know well in advance of submitting their paper. Ideally, they should communicate this during the first class, when the instructor is reviewing the course outline. In this case, you may ask them to submit all of their rough work for an assignment or you may have a short meeting with them and ask pointed questions about their research methodology. Instructors should not be asking students to do anything that might be perceived as additional work. We ask that instructors consult with the Centre for Teaching Support & Innovation when establishing these alternatives.

The University’s plagiarism detection tool Conditions of Use statement is available in all Quercus courses for instructors to copy and paste in the course syllabus.

Plagiarism Detection

Best Practices

It is recommended that you also take a few moments in class at the outset of your course to discuss the use of the University’s plagiarism detection tool and the issue of academic integrity with your students. Please note that while students’ papers are stored in the company’s database, students do retain the copyright on their work.

You may wish to print out student assignments that have been submitted via the Assignment tool in your Quercus course.

Create an Assignment – Quercus integration

Instructors can create a University’s plagiarism detection tool assignment in their Quercus course.

You can follow the directions set out in our Plagiarism Review Tool Guide

NOTE: Instructors do not need to contact CTSI to create an instructor account with the plagiarism detection tool.  Your Quercus login gives you access to the tool via your Quercus course.

The following Quercus course roles can create and view submitted student assignments for textual similarity analysis:

  • Instructor
  • Teaching Assistant

The University’s plagiarism detection tool integration provides textual similarity analysis only.  Student assignments can be annotated and graded as per any assignment using the Canvas SpeedGrader tool.

How Do My Students Submit an Assignment?

Students can submit to a plagiarism detection tool assignment by taking the following steps:

How Do I View Student Assignment Submissions?

You can view any submitted paper from the SpeedGrader, which is accessible from the Assignment or the Gradebook.

How to I Interpret the Similarity Reports?

The Similarity Report highlights textual similarities found within an assignment and provides links to sources that contain similar text.  Similarity Reports highlight passages that may be of concern, but do not automatically report whether a paper has been plagiarized.

Determining if plagiarism has occurred requires analysis by the instructor.

The Similarity Report can be viewed side-by-side with the original paper to facilitate comparison. Textual similarities are highlighted in colour. By clicking on these passages you will be linked directly to the related internet source. If the source of the matching text is a student paper from your class this will be indicated. However, if the match is with a student paper from another course you will be provided with the contact information for the instructor of that class. Thus, the University’s plagiarism detection tool is part of a larger set of tools and resources that assist students with developing their writing and citing skills.

The University’s plagiarism detection tool is an electronic resource that assists in the detection and deterrence of plagiarism. Instructors using this tool can create an Assignment in their Quercus course to which students submit their assignments electronically. Each submitted paper is checked for textual similarity using millions of resources stored in the company’s database. Once analyzed, Similarity Reports (formerly referred to as Originality Reports) are generated within 5-10 minutes for instructors, highlighting questionable areas. Instructors can access and view the Similarity Report in their Quercus course. Using this information as well as any other relevant information, it is then up to the individual instructor to determine if these passages represent plagiarism.

All work submitted to the University’s plagiarism detection tool is checked against three databases of content:

  • A current and archived copy of the publicly accessible Internet (more than 4.5 billion pages updated at a rate of 30-40 million pages per day);
  • Millions of published works (from ABI/Inform, Periodical Abstracts, Business Dateline, ProQuest, the Gutenberg Collection of literary classics, and tens of thousands of electronic books);
  • Millions of student papers submitted to University’s plagiarism detection tool since 1996.

The University’s plagiarism detection tool is available for use in Quercus courses.

Submitted papers are stored in the the company’s database but are not the property of the University’s plagiarism detection tool. Instructors can only access those papers that were directly submitted to their own course. Similarly, students can only access and view the papers that they have submitted in their Quercus courses.

The conditions of use for the University’s plagiarism detection tool apply to both undergraduate and graduate course papers.

Supervisors should ensure that they have the explicit consent of a student before they submit their thesis to University’s plagiarism detection tool.

Under Canadian copyright laws students retain the copyright to any papers submitted to the University’s plagiarism detection tool.  The University’s plagiarism detection tool creates digital fingerprints of student papers – which are not “true derivative works for copyright purposes; they contain only uncopyrightable numerical algorithms regarding the papers but not the papers themselves.” (See their Privacy and Copyright document for more information.)

The intellectual property of all students submitting to University’s plagiarism detection tool is protected by the licensing agreement between the University of Toronto and iParadigms. In addition, this agreement ensures that student papers submitted to University’s plagiarism detection tool will not be used for commercial purposes.

Privacy and Security information 

There are a number of alternate methods that can be implemented, including:

  • requiring annotated bibliographies from students;
  • requiring students submit all rough work with their papers;
  • requiring that students include the call numbers or web site addresses of all sources cited in their paper.

The University’s plagiarism detection tool now handles text correctly in 31 languages in addition to English:

Arabic, Catalan, Chinese (simplified and traditional), Croatian, Czech, Danish, Dutch, Finnish, French, German, Greek, Hebrew, Hungarian, Italian, Japanese, Korean, Norwegian (Bokmal, Nynorsk), Farsi, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swedish, Thai, Turkish

This also means the University’s plagiarism detection tool is indexing many additional websites that contain those languages against which we compare submitted papers.

At U of T, our conditions of use require that students be informed at the outset of the course that the instructor intends to use the University’s plagiarism detection tool. Our practice is to ask students to submit directly to the University’s plagiarism detection tool assignment, rather than having instructors submit on behalf of the students. This ensures that students can opt out of using the program – something that we allow for here without penalty.

And so this means, that instructors cannot submit a paper through University’s plagiarism detection tool without the student’s knowledge. You can ask your student to submit directly to the University’s plagiarism detection tool but you cannot require them to do so.

There are a number of methods that can be implemented as an alternative to using the University’s plagiarism detection tool to check for plagiarism including:

  • requiring annotated bibliographies from students;
  • Requiring students submit all rough work with their papers;
  • Requiring that students include the call numbers or web site addresses of all sources cited in their paper.
