Ouriginal similarity: Online analysis of websites

Ouriginal is a tool, which analyses as many texts found on the internet as possible. These can be found in online-books, websites or earlier assignments submitted through Ouriginal. But there is a limit for what Ouriginal can use for the similarity-rapport. The reasons for Ouriginal not finding a source could potentially be the following:

  1. Some books are uploaded to the internet as a picture-file. Pictures can't be read by Ouriginal
  2. Other texts are encrypted, which means that you will be able to copy the texts but if you paste the text, you will see that many characters will be special-characters
  3. Texts that are behind a paywall, websites that require a login or the accept of cookies to show the texts, are not readable by Ouriginal
  4. Links on websites that directs to download a PDF file are not being matched by Ouriginal as it is not readable online

Statement from Ouriginal:

  • Ouriginal does not claim to find 100% of the matching sources because it is not possible to find every single match! There are several reasons for this, including – we may not have permission to index the source, the site hosting the article may not have been updated in our index, the server hosting the article may have been down at the time we were trying to access it, an error when downloading the source, and many more.
  • What we do instead is show the most relevant and significant sources that indicate that plagiarism may have occurred. This makes the tool more effective for the teacher as they can easily see the most relevant matches instead of having to scroll through dozens of unnecessary sources.

Blocked sources:

some domains might block Ouriginal from accessing their domains when they are investigating and collecting data from all of the internets domains. This can result in lowered similarity percentages if a participant has plagiarised text from a website that is actively blocking Ouriginal from scanning and using their data. As an example, sciencedirect.com blocks Ouriginal from accessing and using their data for similarity reports and alike. So any text plagiarised from this domain will not be recognised in the reports.
