Our Core Technology

We compare documents with other documents around the world – manually, this would take forever.

PlagScan has developed an advanced algorithm to billions of digital sources for semantically related documents through an encrypted connection (256-bit SSL). We examine the internet, publisher databases, your own documents (optionally), as well as the Plagiarism Prevention Pool to search for duplicated content.

 


Our Sources

When checking documents for plagiarism and incorrectly cited passages, it’s important that every single source available is included to be checked against. Only then the results shown in the plagiarism report can be relied upon.

PlagScan automatically includes four types of sources in its plagiarism detection routine:

  1. ‘The Internet’ with 14 billions of digital content available at your fingertips
  2. Millions of scientific and academic articles in journals by the worlds’ most prestigious publishers
  3. Your own document database of previous theses or assignments (optional)
  4. The Plagiarism Prevention Pool with content from other participants of the pool

After the examination of sources, we extract thousands of semantically similar texts and carefully scan them for matches within your document.

The Internet

We use Microsoft Bing as backbone to enhance our web crawling for digital content. By doing so, we ensure that we’re able to constantly stay up to date with the latest content that is published to the internet. Therefore, you can always rest assured that our solution will find the latest articles available.

Millions of Articles in Academic Journals

By cooperating with several of the most renowned scientific publishers worldwide, we ensure that no matter the field of research, every published article on that topic can be accessed - even across a paywall. Professors and instructors can therefore concentrate on the content of the actual paper that was submitted, saving precious time in reading and cross-checking every single article on that specific topic.

PlagScan currently includes over 10.800 journals and 14 million articles by following publishers - and constantly adds more:

  • BMJ
  • Gale, a Cengage company
  • Taylor & Francis 
  • Wiley Blackwell
  • Springer
  • And many more

Collusion Checking With Your Own Documents

No matter if your organization is a university, high school or business: Chances are high that someone else may have already written a document on the assigned or discussed topic. As an option, PlagScan provides the opportunity to build up your own database consisting of assignments, theses or articles that have been added to your repository. This ensures originality for every submitted document.

Documents in the Plagiarism Prevention Pool

As a way to ensure that universities can cross-check assignments in different regions and to make sure that they haven’t already been submitted at another university or school, PlagScan users can participate in the global Plagiarism Prevention Pool. This index of documents lists every submitted document, and ensures that credit is given where credit is due. Read more about the Plagiarism Prevention Pool here.


Our Algorithm

Three consecutive word matches constitute the basic element of our plagiarism detection algorithm to ultimately find plagiarism despite the text being reordered or containing synonyms.

At the end of the detection process, we apply artificial intelligence to identify direct quotations, insignificantly small matches and whitelisted content, in order to present you with the most comprehensive results.

Our in-house indexing technology is based on Apache Solr™.
