Plagiarism detection

What is the file upload limit?

Approximately 100MB, there is no limit to number of pages.

What file formats does StrikePlagiarism support?

Supported file formats: DOC, DOCX, ODT, RTF, PDF, PPT, PPTX and many others.

PDF/A files are read-only and may not be supported.

What languages ​​does StrikePlagiarism support?

StrikePlagiarism supports languages ​​spoken in European countries. The functionality that translates the document into the selected language and searches for overlaps, including synonyms, is supported.

Can it recognize AI-generated text?

Yes, StrikePlagiarism can recognize text generated by the most common language models such as ChatGPT, GPT-2, GPT-J, GPT-NEO, GPT-3 or GPT-4.

How can a student submit their work for analysis?

The student can submit his work through Moodle or the StrikePlagiarism online environment. There is no functionality to send via e-mail as it was in Ouriginal.

Can work be submitted for analysis directly from Google Docs?

No, cloud-based text formats are not compatible with StrikePlagiarism. A link to the document location is not enough, the document must always be submitted as a separate file.

What do SC1 and QC mean in the report?

SC1 (Similarity Coefficient) shows the overlapping result and QC (Quote Coefficient) shows the number of citations in percentage.

Is it possible to delete a document uploaded to StrikePlagiarism?

For this, please contact moodle@taltech.ee.

How long does it take to analyse one document?

Depending on the volume of the document, it usually takes 20 minutes, in some cases up to 24 hours, to analyse one document submitted for review.

The student submitted his/her work several times. Does it affect the analysis result of his/her work?

If the work is accepted in the report and thus sent to the database, the new submission is compared against the old one. In Moodle, make sure that "Adding documents to reference database" is set to "Manually after marking" in the Assignment settings.

Why does the report indicate the list of used literature as overlapping?

This occurs when the list of used literature is not numbered or certain keywords (e.g. Bibliography, Literature, References) are missing.

I'm not getting StrikePlagiarism email notifications. What to do?

Separate notifications are not sent for each document. However, in certain cases, notifications may have ended up in spam.

Is it also possible to exclude the overlapping source in the report?

Yes, it is. Excluding sources only works if the document has not yet been added to the database. Read more on page 15 of the user manual.

Is it possible to share a similarity report from Moodle?

It is not possible at the moment, but it is possible through the http://strikeplagiarism.com environment. Contact moodle@taltech.ee to find an alternative solution.
