For more than a decade, Turnitin has been refining the process of comparing papers to a vast repository of data to deliver originality reports in just a few seconds.

Content Comparison

  • The Turnitin Web Crawler scans and indexes new and existing content from the Web in the Turnitin database.
  • A student uploads a paper to Turnitin.com
  • The paper is compared to millions of books/publications; over 45 billion web pages; and 337 million student papers.
  • Results are returned in seconds, showing matches of the student paper to content from the Turnitin database.

Content Databases

When a paper is submitted to Turnitin, it is compared against three vast databases of content from three primary sources:

  • The Current and Archived Web: Similar to Google and Bing, Turnitin has built a web crawler that crawls the Internet and indexes content into a searchable form. Turnitin currently contains over 45 billion web pages from the current web as well as archived web pages.
  • Student Papers: Over 50 percent of plagiarism comes from other student’s work. Turnitin compares submitted papers to a database of over 337 million papers in the Turnitin paper database. Each day, the Turnitin student database grows by 190,000 papers.
  • Content Partnerships: Turnitin has partnered with leading content publishers, including library databases, text-book publishers, digital reference collections, subscription-based publications, homework helper sites and books. These partnerships have contributed over 130 million additional articles to our databases.
