Ouriginal is a plagiarism detection tool that can be activated for Brightspace Assignments. After setting up an Assignment, you can enable Ouriginal to check assignments for plagiarism. Students can submit their written, electronic assignments through Brightspace Assignments.
Creating Ouriginal assignments consists of three steps:
• Creating an Assignment.
• Enabling Ouriginal for the Assignment.
• Making the Assignment available to students.
Students can then upload Assignments and view their similarity reports (if enabled).
If you are missing sources, please use the temporary workaround in the ‘Viewing the similarity report section‘.
Please be aware that any draft submissions enabled for plagiarism can interfere with the student’s final submission results. This means if a different staff member enables the plagiarism tool in another assignment, the student’s submissions will be treated as separate files, often resulting in a very high similarity score (usually 100%). See also the FAQ on self-plagiarism at the bottom of this page.
Set up Ouriginal
- Create an Assignment. Please take a look at Creating Assignments for more information about how to set up an Assignment.
- Click on Ouriginal in the menu bar of your course (next to Assignments).
- On the Similarity Detection Overview you will see an overview of all your assignments. Under Turn On/Off Similarity Detection you can enable Similarity Detection for your assignment. When the slider is to the right, it is activated for your assignment.
Students are not able to see whether Ouriginal is enabled for an assignment. Please inform them, for example, through an announcement.
Please be sure to watch out for accidental self-plagiarism. If a student submits the same or an updated document to an assignment created by another instructor than the original assignment, the document will be viewed as plagiarism, regardless of the course in which the assignment is given. If this happens, the instructor can exclude a source using the “Sources” tab in the relevant report to ensure that it is not considered plagiarism. More information can be found in the FAQ Can a student commit self-plagiarism?
- Optional: You can also activate Display Similarity Report to Students upon submission, which allows students to view the similarity report of their own submission. Students see the same report as lecturers see in Ouriginal, with some details removed. When a student makes any changes in a report (excluding resources from the similarity report) it will not affect the report of the lecturer and vice versa.
It is important to note that students must submit their assignments themselves to be able to draw plagiarism reports.
Students can submit the assignment in the relevant course in Brightspace using the Assignment tool. The student will receive an automated email from Brightspace confirming the successful submission.
All uploads will be included in the Ouriginal repository, except for documents uploaded via the Quick Submit for teaching staff. For more info, see the FAQ section.
The maximum file size for uploading to Ouriginal is 200MB. If you need to upload a larger document, like a PhD thesis, rather break up the document into chapters, or parts no larger than the maximum file size.
The file formats that are currently supported by Ouriginal are: .doc, .docx, .xls, .xlsx, .sxw, .pptx, .pdf, .pdf2.0, .txt, .rtf, .html, .htm, .wps, .odt, .odp, .ods, .tif, .tiff, .ps, .hwp and .pages. LaTeX files are unfortunately not supported. It is best to convert a LaTeX file to flat text before uploading it to Ouriginal.
Ouriginal accepts pdfs in general, however, some come from legitimate and illegitimate Word to pdf converters, where the text extracted from them turns into strange symbols, which are not possible to analyse. These are often rejected by the system. We also cannot accept images converted to a pdf format. Documents submitted to Ouriginal may not contain any protection or encryption
There are two ways to reach the Ouriginal similarity report: through Assignments and through Ouriginal in the navigation bar.
Anyone with a teaching role in the Brightspace course (course manager, instructor and teaching assistant) can access the Ouriginal similarity report.
If you see the Brightspace homepage content after clicking Ouriginal in the top navigation bar instead of the Ouriginal tool content, please try again using a recommended browser like Google Chrome or Firefox, after you've removed all browser cookies for Brightspace.
Accessing an Ouriginal report through the Assignments menu:
Ouriginal similarity scores can be seen when viewing assignment submissions in the Assignment submissions. The similarity score is presented as a percentage-similar icon and is visible on the Users tab. A score with a higher percentage indicates that the document is more similar to a document found in Ouriginal’s body of content. Instructors can click on the percent-similar icon to view a detailed report. If a warning icon is present above the percent-similar icon, Brightspace failed to retrieve a similarity score for this document.
To access the updated view and the Ouriginal report:
- Click on Assignments in the course’s navigation bar
- Open the assignment you wish to view
- The overview includes a color-coded similarity score, as below.
- To view the similarity report on the Ouriginal site, click on the displayed score.
If you see ‘Error’ instead of the expected similarity percentage, please contact Teaching & Learning support.
Accessing an Ouriginal report through the Ouriginal menu:
- Once logged into Brightspace, select the course that contains the assignment you’d like to view Similarity Reports for.
- From the top navigation bar, select Ouriginal.
- Go to Similarity Submission Details. You will see an overview of all the submitted assignments from students. You can also filter on a specific assignment, or search for a specific student or group by using the Filters button.
- Click on Show Details for the report you want to view. Then click on the name of the document, and click on View Report. A new window will open, where you have to login using your TU Delft NetID and password.
Once logged in, in the new window you will see an overview of the document, along with document details and the sources of the potential plagiarized material. You can also download the report in PDF format; you can do this on the top right of the page with the download button.
If you are missing sources in the similarity report, please use this temporary workaround:
- When logged into Ouriginal you can find a button in the Options menu named ‘Back to old Urkund’:
- Click on it to switch back to the old view. In the old view, under Sources > Sources not used, you will find the complete list of sources.
If you notice sources within that list in Sources not used that clearly shouldn’t be there, please contact Teaching & Learning Support.
To return to the new view, simply reopen the report from the link within Brightspace as instructed before.
Please note that the percentage of the similarity report is not a concrete percentage of plagiarism in the document. This is an indication of the amount of suspicious text in the document. Always check and evaluate whether the highlighted text is plagiarism or not.
The Analysis overview is the landing page from the Ouriginal report. A summary of the results is presented on this page. It shows the number of text matches and warnings, where these were found in the document and the overall similarity percentage.
- Submission Details: You can find all the necessary information about the document including the unique submission ID.
- Tabs: here, you can find the different views that Ouriginal offers.
- Document Overview Bar: This bar is used to quickly look at the document's findings. More details about that specific match or warning will show by clicking on a finding.
- Findings: This box shows the number of matching texts and warnings (warnings do not affect the similarity score, they show an unusual use of characters in the document).
- Similarity: Three similarities are displayed; the assignment’s aggregated similarity percentage, the submitter’s average, and the Group's average similarity. The submitter's average and group average can be affected by various reasons, please disregard these scores. If there are not enough submissions to create an average, these will be greyed out.
- Reset Option: The arrow button will reset the report to its original state (e.g. if you have excluded findings and therefore wish to restore it).
The Findings tab shows the student’s text next to the matched source text. It presents the matches one by one. Use the Entire Document tab to scroll through the entire document.
- Types of findings: Navigate between the different finding types – Matching text, Warnings and Crossmatches.
- Submitted text vs matching text: The text matches are displayed with the submitted student text on the left and the text from the matching source on the right. The percentage refers to the text match for this particular block of text.
- Previous/Next match: you can navigate through the different matches here.
- Source Info and Link: This is the link to the original source. It will also show the type of the source, where Personal archive means documents that were previously submitted to Brightspace via Turnitin, Publisher sources mean sources found in scientific publications, Ouriginal archive means student works, and Internet sources are sources that are publicly accessible via Internet.
- Alternative sources: Ouriginal shows matches that the algorithm deems most relevant. It is possible to show alternative matches in the findings tab.
- Exclude this match: If a finding is considered too irrelevant, it is possible to exclude it from the report. It will then no longer affect the document’s aggregated similarity.
The Sources tab lists all original sources found in Ouriginal’s analysis. The Ouriginal algorithm searches for the least sources with the highest similarity. For example, imagine a similar text can be found on the same Wikipedia page, but it can also be found in three different journals. Ouriginal will then show the Wikipedia page as level 1, because it has the most similar text but the least different sources, and the three different journal pages as level 2, since they have similar text but multiple sources. In the sources tab, it is possible to Exclude a Source or switch to an alternative source. It is also possible to report a missing source URL to Ouriginal, a request to index this source is then sent to Ouriginal.
On this page, you can also filter on the type of sources; you can find this filter button in the top right of the screen.
The submitted document is shown in its entirety here. Coloured parts of the document indicate matching text or warnings. Orange means matching text, and purple means a warning. On the right side of the page, you can choose to display the list of Sources, or display a side-by-side comparison between the text of the submitted document and the text of Findings.
Ouriginal Quick Submit for Teaching Staff
Ouriginal Quick Submit is a tool for Teaching staff to use Ouriginal without having to set up Ouriginal within a Brightspace course. This can be useful when only 1 or 2 documents need to be submitted. As teaching staff, however, you will have to manually upload all assignments one by one, which is why it is recommended to set up Ouriginal within your own course when dealing with large numbers of assignments.
It takes up to 30 minutes to see the similarity report after uploading the assignment. Afterwards the report can be viewed by selecting Ouriginal and then Plagiarism Submission Details.
Assignments handed in via Ouriginal Quick submit will be stored in the Ouriginal database, however, they are not used for future similarity reports.
All Teaching Staff with a TU Delft employee account (@tudelft.nl) can gain access to the Ouriginal Quick Submit for Teaching Staff – course.
- Go to the Catalog via the Brightspace Homepage.
- Search for Ouriginal Quick Submit for Teaching Staff.
- Select Request Approval.
- Approval will be given manually by Brightspace support, this can take some time.
When encountering problems, please contact Teaching & Learning Support.
To learn how to use the Ouriginal Quick Submit tool, please read the guide available in the Ouriginal Quick Submit for Teaching Staff course in Brightspace under Content > Ouriginal Quick Submit
Is it possible to import text/exclude sources by default that should not be taken into account for the similarity reports?
I see a tertiary source (e.g. Wikipedia) instead of a primary source that I would've expected (scientific article). Why is this?
When using Ouriginal, are documents still scanned towards work handed in in TurnitIn previous years?
