To find a student's similarity report, go to Grades in Canvas.

Click on the "coloured flag" to open a student's similarity report

As soon as a student hands in the assignment, you see a coloured flag. This tells you the similarity report is created and what the percentage of similarity is:

- **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

Turnitin will only accept files that can generate Similarity Reports. This includes:

- files less than 100MB,
- files with a minimum of 20 words
- file less than 800 pages
- Microsoft Word (DOC and DOCX)
- Corel WordPerfect
- HTML
- Adobe PostScript
- Plain text (TXT)
- Rich Text Format (RTF)
- Portable Document Format (PDF)
- OpenOffice (ODT)
- Hangul (HWP and HWPX)

Click "Speedgrader". In Speedgrader you can annotate and grade as you normally do.

Click on the coloured percentage. The report will open in a new window.

The first time you open a report you have to accept the End-User License Agreement (EULA).

Make sure you accept the End-User License Agreement (EULA) the first time you go to Turnitin. When you don't accept the EULA you might receive an error (error 431) when opening a similarity report in Turnitin. 

Notice that you can also switch to the new view now. This has a few advantages. More information can be found in the Canvas Training course on the page about[Turnitin Originality](https://canvas.maastrichtuniversity.nl/courses/49/pages/turnitin-originality-plagiarism-check?module_item_id=525355).

Here you find the submission details. The paper ID is useful as a reference when you have a question or experience a problem. You also find the word count and submission date.

Click "Overall Similarity".

Here you find the overall similarity percentage. This is the percentage of the paper that is found in the Turnitin Database.

Click "All Sources" to see not only the top sources, but all sources.

You can exclude a specific source by clicking on the eye.

When you click on a specific source you find more information about the source.

Click the little wheel (settings) in the right corner.

In settings you can find several possibilities to exclude matches. You can exclude:

- specific repositories
- parts of the submission like the bibliography, quotes or citations
- small matches, because they are often irrelevant

Find more information about the content of the databases of Turnitin on the website of Turnitin <https://www.turnitin.com/about/content>

Excluding the bibliography can be interesting, because the similarity found here is often irrelevant. However, including the bibliography might also give information when references **don't** show similarity. This could be an indication references are made up by the student or by AI.

Click "Flags" to find out about suspicious finds in the document.

Click "Replaced characters" to see which characters have been replaced.

Click "Hidden text" to see which text has been hidden.

Always have a look at these flags, because these are important warnings for manipulations in the document. 

Click "Document Details" to find more information about the document.

You find more information about the fonts being used in the document and about the words used in American and British spelling. These findings could give an indication of possible fraud.

After you click the AI Writing tab in the report, you find which text has been determined to be generated by AI.

If you want to learn more about how the AI writing detection works, you can find an [FAQ on Turnitin's AI writing detection](https://guides.turnitin.com/hc/en-us/articles/28477544839821-Turnitin-s-AI-writing-detection-capabilities-FAQ)

The AI writing score is divided into two detection categories:

AI-generated only: This category detects qualifying text that was likely generated from a Large Language Model (LLM). Text of this category is highlighted in a cyan color in the submission breakdown bar and in the submission.

AI-generated text that was AI-paraphrased: This category detects qualifying text that was likely AI-generated and then likely modified by an AI-paraphrasing tool or AI word spinner, such as Quillbot. Text of this category is highlighted in a purple color in the submission breakdown bar and in the submission.

For the AI Writing Detection to work the submission needs to meet the following requirements:

- File size must be less than 100 MB

- File must have at least 300 words of prose text in a long-form writing format

- File must not exceed 30.000 words

- File must be written in English

- Accepted file types: .docx, .pdf, .txt, .rtf

What to do when you want a thesis to be checked on AI, but it exceeds 30.000 words?

- You could ask students to submits the appendices as separate documents.
- You could split the document yourself and hand both documents in via the Turnitin Originality web portal.
