Turnitin is a Web-based service that identifies passages in submitted papers that match passages in other sources, such as websites, articles in scholarly journals, and other student papers. TurnItIn then generates an Originality Report, which highlights passages of matching text. See more information on Turnitin here. Turnitin does not state outright whether or not plagiarism has occurred. Plagiarism is a large category that includes many different behaviors, ranging from poorly paraphrasing a cited source to purchasing a paper and submitting it as one’s own work. While no software can make a blanket statement about whether a paper contains plagiarism, Turnitin does provide originality reports that show which passages from submitted papers match other sources. To make a determination about whether a paper contains plagiarized material, analysis is required. Originality reports make analysis easier and more convenient.
