Originality Check

Overview

 

A typical submission made to an assignment in Turnitin generates a Similarity Report. The Similarity Report is the result of comparison between the text of the submission against the search targets selected for the assignment; this may include billions of pages of active and archived internet information, a repository of works previously submitted to Turnitin, and a repository of tens of thousands of periodicals, journals, and publications. Any matching or highly similar text discovered is detailed in the Similarity Report that is available in the Assignment Inbox.

 

1. To access a Similarity Report, you must firstly access the main homepage by clicking the All Classes tab from the top of any page

Similarity Reports

 

Similarity Reports provide a summary of matching or highly similar text found in a submitted paper. When a Similarity Report is available for viewing, an icon will appear in the Similarity column of the Assignment Inbox. Similarity Reports that have not yet finished generating are represented by a grayed out icon in the Similarity column. Reports that are not available may not have generated yet, or assignment settings may be delaying the generation of the report.

 

Screen Shot 2015-04-23 at 11.58.36 AM.png

 

Note: Overwritten or resubmitted papers may not generate a new Similarity Report for a full 24 hours. This delay is automatic and allows resubmissions to correctly generate without matching to the previous draft.

 

The color of the report icon indicates the Similarity Index of the paper, based on the amount of matching or similar text that was uncovered. The percentage range is 0% to 100% The possible similarity indices are:

 

  • Blue - No matching text
  • Green - One word to 24% matching text
  • Yellow - 25-49% matching text
  • Orange - 50-74% matching text
  • Red -75-100% matching text

Similarity Report Accepted File Types

 

The following file types are able to generate Similarity Reports: 


Microsoft Word® (DOC and DOCX), Corel WordPerfect®, HTML, Adobe PostScript®, Plain text (TXT), Rich Text Format (RTF), Portable Document Format (PDF), Hangul (HWP), Powerpoint (PPT, PPTS, and PPS).

 

Warning: These indices do not reflect Turnitin’s assessment of whether a paper has or has not been plagiarized. Similarity Reports are simply a tool to help an instructor find sources that contain text similar to submitted papers. The decision to deem any work plagiarized must be made carefully, and only after in depth examination of both the submitted paper and suspect sources in accordance with the standards of the class and institution where the paper was submitted.

Viewing Similarity Reports

 

The Similarity Report can be viewed in one of four modes. These modes allow users to view and sort the information contained in the Similarity Report in any way best suited to their needs. The four modes for viewing an Similarity Report are: 

 

  • Match Overview (show highest matches together): A list of all areas of the paper which have similarity to information in the Turnitin repository. Matches are color coded and listed from highest to lowest percentage of matching word area to the submission. Only the top or best matches are shown, all underlying matches are visible in the Match Breakdown and All Sources modes
  • All Sources: Allows a user to view matches between the paper and a specific selected source in the Turnitin repositories. Contains a full list of all matches found rather than the best matches per area of similarity. This listing is exhaustive but will show all matches found, including any that are obscured in the Match Overview by virtue of being in the same or similar areas as other, better matches
  • Match Breakdown: Displays matches that are obscured by a top source. Allows instructors to compare the match instance of a underlying source with the match instance for a top source
  • Direct Source Comparison: An in depth view that shows an area of similarity compared side by side with a specific match from the Turnitin repositories. Not available on all types of repository matches

 

Note: If the source of matching text is a student paper in one of the classes controlled by the user as an instructor, the paper can be displayed in direct source comparison mode with matching text highlighted. The Similarity Report provides the instructor with information regarding the origin of the matching paper. Not available for students viewing Similarity Reports.
 
If the paper is from a class controlled by another instructor, no direct access to this paper can be provided. To view the paper, the instructor must request permission from the instructor in possession of the paper by clicking on the link to the source and then using the permission request button. Turnitin will auto-generate an e-mail request to the instructor who controls the paper. The instructor can reply via e-mail to the user if the request is granted. No student papers are made available to another user within the Turnitin system.

Similarity Report Contents

 

The Similarity Report is separated into three main areas: 

 

  • Document viewer frame - shows the Similarity Index for the report and the title and author of the paper
  • Paper text - the submitted paper’s text in its original formatting. Matching text is highlighted in a color that corresponds to the matching source listed on the right side of the Similarity Report
  • Matching sources/sidebar - the list of matching sources for the highlighted areas of the paper text to the left. The sidebar also displays the Filter and Settings (exclusion options) and the Exclusion List

Direct Source Comparison

 

Direct Source Comparison, allows a user to quickly compare matching text to the source of the match in the Turnitin repositories. Matches to other student papers are not available for Direct Source Comparison viewing unless the students’ are enrolled in your class. Using Direct Source Comparison can be done from the Match Overview or the All Sources view mode of the Similarity Report.


Users can either view the Direct Source Comparison as a glimpse within the paper or as the Full Source Text within the sidebar. The glimpse only provides the matching text within context of a few outlying sentences from the source while the Full Source Text loads in the sidebar and contains the full text of the source and all the match instances.

Accessing direct source comparison

 

1. To access a direct source comparison, you must firstly access the Similarity Report. Visit the main homepage by clicking the All Classes tab from the top of any page

Note: If an area of submission text is matched to a source in the student paper repository on Turnitin, it will be listed as student papers. Direct Source Comparison is not available to students for student paper matches. Instructor users are able to send an Email request to the instructor who received the matching paper. If one instructor user profile controls the class containing both papers, that instructor user is able to see the paper in direct source comparison.

Repository Sources

 

Turnitin utilizes multiple types of repositories in the generation of the Similarity Reports. There are currently four types of repositories: 

  • Current and archived internet - Billions of active and archived web pages from the internet. Internet sources indicate a date of download on the Turnitin Similarity Report if the match is not found on the most recent download of content from this site   
  • Institution paper repository - The institutions paper repository of student papers
  • Periodicals - A repository of frequently updated content from professional journals, periodicals, and publications
  • Student paper repository - A repository of papers previously submitted by Turnitin users

Excluding Quoted or Bibliographic Material

 

If quoted or bibliographic material is flagged as similar or matching, this information can be removed from the Similarity Report. Permanent exclusion of bibliography or quoted material can only be handled by the instructor. Students are only able to remove quoted or bibliographic material for the duration of the current session of viewing the Similarity Report.


Please note that the functions for excluding material are approximate and human judgment is the final arbiter for proper quotation or bibliographic reference. Cited material cannot be excluded directly, and quotations can only be excluded if block indentation or direct quotation marks (“”) begin and end the quotation.

 

1. To exclude quoted or bibliographic material, you must firstly access the Similarity Report. Visit the main homepage by clicking the All Classes tab from the top of any page

Regenerating Reports

 

Since new material is constantly entering Turnitin’s repositories from ongoing internet crawls, new publication content, and submissions made to Turnitin, it is sometimes beneficial to generate a new Similarity Report for a student submission at a later date to see if there are any new matching sources, or to ensure that it checks against later submissions made by other students or other classes. 

 

The option to refresh a report is available on the Similarity Report once it has opened. The current report is deleted and a new report is generated. Please note that no report will be available until the new report has finished. If the user wishes, they can save or print a copy of the existing report before selecting the New Report option in the Filter and Settings sidebar to have a new Similarity Report generated.
