Viewing and interpreting the Similarity Report

Viewing the Similarity Report

There are two ways to reach the Ouriginal similarity report: through Assignments and through Ouriginal in the navigation bar.

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:

  1. Click on Assignments in Course Tools
  2. Open the assignment you wish to view
  3. The overview includes a color-coded similarity score, as below.
  4. To view the similarity report on the Ouriginal site, click on the displayed score (see image below)
Accessing an Ouriginal report through the Ouriginal menu:
  1. Once logged into Brightspace, select the course that contains the assignment you’d like to view Similarity Reports for.
  2. From the top navigation bar, select Course Tools and then Ouriginal.
  3. Go to Plagiarism 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(see image below)
  4. 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 with a report (see details below).

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 (see headlined below)

Interpreting the Similarity Report

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.

Analysis Overview

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.

  1. Document Overview Bar: This bar is used to have a quick look at the findings in the document. By clicking on a finding, more details about that specific match or warning will show.
  2. 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).
  3. Similarity: Two similarities are displayed; the assignment’s aggregated similarity percentage and the receiver’s average similarity. The receivers average can be affected by various reasons, please disregard this score.
  4. Submission Details: Here you can find all necessary information about the document including the unique submission ID.
  5. 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).
Findings Tab

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.

 

  1. 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.
  2. Include/Exclude Finding: If a finding is considered too irrelevant, it is possible to exclude the finding from the report. It will then no longer affect the document’s aggregated similarity.
  3. Types of findings: Navigate between the different finding types – Matching text, Warnings and the Bin (which is where excluded findings end up).
  4. Source Info and Link: This is the link to the original source. W meaning website, SA is for a student assignment and J for content from a journal.
  5. View alternatives: Ouriginal shows matches that the algorithm deems most relevant. It is possible to show alternative matches in the findings tab.
Source Tab

The Sources tab shows the list of all original sources found in Ouriginal’s analysis.. Next to the source, you find the number of alternative overlapping sources found by Ouriginal. 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 send to Ouriginal.

Entire Document Tab

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. Click on the Finding icon left from the text to open a side-by-side comparison.
