Can iThenticate be used by Admissions Offices?

Yes. For Admissions offices, iThenticate has an easy to use submission process that checks incoming application documents (essays, short answers, letters of recommendation, etc)  for similarity against the world’s top published works and a repository of more than 70 billion current and archived web pages. The written portions of the application packet are the most subjective and take the most time to review, so having a solution that provides a quantifiable metric without increasing the review time helps to protect your reputation while fitting seamlessly into your current application review process.

Against what resources will my manuscript be compared?
iThenticate compares submissions to premium academic content including: premium scholarly journals, books, law reviews, patents, dissertations & theses, pre-prints, conference proceedings and internet pages.  Learn more about our constantly growing database of content

Are my submissions to iThenticate kept private?

If using the zip file upload method, all files contained in a zip file are extracted and uploaded one by one. Each one will be considered a separate upload and will use up a single credit even if the 25,000 words are not fully used, the remaining words do not roll over.

A revision is when you submit a manuscript that you have already uploaded to iThenticate and you have either revised it or added more material to it and want to check your manuscript again. 

How many times can I submit a manuscript for a plagiarism check?
After you submit your document once, you may resubmit it a maximum of five times. If your revised manuscript is substantially different (60%) than the first submission, iThenticate may ask you if you would like to submit the revision as a new manuscript.

Can editors see my Similarity Report?
No. iThenticate gives you your own personal account so that you can check for plagiarism privately. This means that no one can access it but you. If you would like to share your report, you can download a PDF version to print or email. 


Reports

What do iThenticate reports highlight?
iThenticate identifies material that matches text from documents found in our extensive database. Highlighted text will include text that has been properly quoted and cited so it is not necessarily plagiarized. You will need to verify that every highlighted section has been properly quoted, summarized or paraphrased. As a result, iThenticate makes it easier for you to identify and attribute any material in that may contain unintentional plagiarism.

How long will I have to wait until my results are ready?
Results are usually delivered within one minute to several minutes, depending on document length.

How will I know if my results are ready?
While this analysis is in progress, you will see the word "pending" in the report column next to the title of your manuscript. When your results are ready, you will see a percentage, or "Similarity Index" in the report column next to the title of your manuscript.

How do I see my results?
To see your results, click the "Similarity Report" icon in the report column next to the title of your manuscript.

What does the percentage mean?
The results include a percentage score, called a "Similarity Score", which indicates how much of the document matches other sources. Please note that iThenticate does not determine whether a manuscript contains plagiarism. The service identifies content in a submitted manuscript that matches other sources, primarily to encourage the author of the manuscript to check that other sources have been properly cited. Watch a demo

What do the highlighted boxes mean?
The results include number-coded and color-coded highlighting of parts of the manuscript that correspond to matching sources in the iThenticate database. You are encouraged to look carefully at these portions to determine whether other sources have been properly cited.
