Duke University has chosen iThenticate as the anti-plagiarism tool for the Duke research community

Using iThenticate allows early detection of potential plagiarism before works are disseminated. Using iThenticate can serve as both a teaching tool and a preventative measure to help ensure research manuscripts, grant applications, and scholarly documents have the appropriate citations and references of previously published work before submission to journals, funding agencies, and academic repositories.

How iThenticate can help you

If you are Faculty or a Researcher: iThenticate helps you detect un-cited or improperly cited material in manuscripts, grant proposals or other written documents so that you can correct the text before it is submitted. This is particularly useful because publishers and funding agencies, such as NSF and NIH, use plagiarism detection tools to screen manuscripts or grants upon submission.

You can use iThenticate to screen student dissertations, theses and final papers before submission or committee review. If you do so, you must be transparent and inform students in advance.

If you are Program Staff: iTheticate helps you identify improperly cited material so that you can revise the text before final submission for peer review, editorial decisions, committee examination, archiving, etc. You can use iThenticate to screen student dissertations, theses and final papers before submission or committee review.

If you do so, you must be transparent and inform students in advance. Advise students and mentees that instructors, publishers, funding agencies, the Graduate School, et al may screen their submissions through similar plagiarism detection software.

If you are a Student: iThenticate can serve as a learning tool, to help you identify sections of your writing that may need additional editing or re-writing when the tool detects text matches to other published texts.

Ask your faculty advisor or departmental staff to screen your papers, theses or other written documents before you submit them.

An overview of how iThenticate works

The process for using iThenticate is simple and relatively fast, taking only about 5-15 min to scan each document. 

  1. iThenticate users upload a document into their private cloud-based iThenticate accounts.
  2. iThenticate compares all text in that document to the text from an extensive and continually updated library of published materials and websites.
  3. iThenticate generates an interactive report to highlight the text from the user’s document that match text from outside published texts.

This report can be exported and provides an overall similarity score, the percentage of the user’s document that matches text from the library of published materials. Once iThenicate creates the report, the user can evaluate whether any matching similarities found in the text will require further discussion and re-writing.
