Exploring How Turnitin Checks Submitted Documents Against Each Other and in Its Database
Turnitin is a widely used tool in academic settings to ensure the originality and integrity of submitted documents. This article delves into how Turnitin checks submitted documents, both against each other and against its vast database. We will also explore the implications of storing submitted documents and the options instructors have to customize this process.
Understanding Turnitin's Document Comparison Process
Turnitin's primary function is to identify potential plagiarism by comparing submitted documents to a vast database of academic sources, student submissions, and content available on the internet. This comprehensive database includes previously submitted papers, academic publications, and web content. When multiple students submit similar documents, Turnitin can detect these similarities not only within the group but also against its entire repository. This level of detail helps educators ensure that student work is original and properly cited.
How Turnitin Stores and Utilizes Submissions
Most submitted documents are stored in the Turnitin repository, which means that these documents become part of the database for future comparison. This wide-scale storage ensures that all future submissions are checked against the entire database, enhancing the accuracy and reliability of the plagiarism detection process. However, instructors have the option to disable the inclusion of certain submission types in the repository to prevent internal sharing or external sale of documents.
Accessing Originality Reports
Instructors can access detailed Originality Reports that highlight matching phrases, sentences, and re-worded paragraphs. These reports indicate whether the matches originated from online articles, websites, publications, or other student-submitted papers. The reports also facilitate easy comparison between the source material and the submitted document, allowing instructors to assess whether proper attribution has been given or if plagiarism has occurred. This transparency is crucial in maintaining academic integrity.
Strategic Exclusions from the Repository
While the default is to include submissions in the repository, there are situations where this might be counterproductive. For example, early drafts of papers or chapters in a cumulative thesis may be submitted as part of the final project. In such cases, instructors can disable the inclusion of these documents in the repository. This ensures that the internal sharing of these drafts is controlled and does not affect the plagiarism detection process. Strategic exceptions like these allow for a more nuanced application of Turnitin's tools.
Retention of Submitted Documents in Turnitin
Documents submitted to Turnitin on academic contracts remain in its database forever. This permanent retention helps in identifying cases where students might copy each other's work. In contrast, personal accounts may have varying retention policies, which students and instructors should be aware of for security and privacy reasons.
Understanding how Turnitin checks submitted documents and its broader database, as well as the options for customizing this process, is essential for educators and students alike. This knowledge empowers both parties to uphold academic integrity and ensure the originality of their work.
