In May, we updated you on the latest changes and improvements to the new version of iThenticate and let you know that a new similarity report and AI writing detection tool were on the horizon.

On Wednesday 1 November 2023, Turnitin (who produce iThenticate) will be releasing a brand new similarity report and a free preview to their AI writing detection tool in iThenticate v2. The AI writing detection tool will be enabled by default and account administrators will be able to switch it off/on.

In 2022, we flagged up some changes to Similarity Check, which were taking place in v2 of Turnitin’s iThenticate tool used by members participating in the service. We noted that further enhancements were planned, and want to highlight some changes that are coming very soon. These changes will affect functionality that is used by account administrators, and doesn’t affect the Similarity Reports themselves.

From Wednesday 3 May 2023, administrators of iThenticate v2 accounts will notice some changes to the interface and improvements to the Users, Groups, Integrations, Statistics and Paper Lookup sections.

Since we announced last September the launch of a new version of iThenticate, a number of you have upgraded and become familiar with iThenticate v2 and its new and improved features which include:

• A faster, more user-friendly and responsive interface
• A preprint exclusion filter, giving users the ability to identify content on preprint servers more easily
• A new “red flag” feature that signals the detection of hidden text such as text/quotation marks in white font, or suspicious character replacement
• A private repository available for browser users, allowing them to compare against their previous submissions to identify duplicate submissions within your organisation
• A content portal, helping users check how much of their own research outputs have been successfully indexed, self-diagnose and fix the content that has failed to be indexed in iThenticate.

We’ve received some great feedback from iThenticate v2 users and user testers:

Some context

The Similarity Check Advisory Group met a number of times last year to discuss current and emerging originality issues with text-based content. During those meetings, the topic of image integrity was highlighted as an area of growing concern in scholarly communications, particularly in the life sciences.

Over the last few months, we have also read with interest the recommendations for handling image integrity issues by the STM Working Group on Image Alteration and Duplication Detection, followed closely image integrity sleuths such as Elizabeth Bik and have, like many of you, noticed that image manipulation is increasingly given as the reason for retractions.

Crossref Similarity Check news: iThenticate v2.0 ready for launch

Last year, we announced the upcoming launch of a new version of iThenticate, the product from Turnitin that powers Crossref Similarity Check. We know some of you have been waiting a long time for this upgrade and we are very happy to share with you that we are now ready to release it.

We will be rolling out this new version in stages, so not everyone will be able to upgrade to the new version immediately. We’ll start with new Crossref Similarity Check subscribers who use iThenticate in the browser, and one member who uses iThenticate via the eJournalPress API integration.

Crossref’s Similarity Check service is used by our members to detect text overlap with previously published work that may indicate plagiarism of scholarly or professional works. Manuscripts can be checked against millions of publications from other participating Crossref members and general web content using the iThenticate text comparison software from Turnitin.

Tl;dr

Crossref is taking over the service management of Similarity Check from Turnitin. That means we’re your first port of call for questions and your agreement will be direct with us. This is a very good thing because we have agreed and will continue to agree the best possible set-up for our collective membership. Similarity Check participants need to take action to confirm the new terms with us as soon as possible and before 31st August 2019. Instructions will be circulated early June via email.

Today, I’m thinking back to 2008. A time when khaki and gladiator sandals dominated my wardrobe. The year when Obama was elected, and Madonna and Guy Ritchie parted ways. When we were given both the iPhone 3G and the Kindle, and when the effects of the global financial crisis lead us to come to terms with the notion of a ‘staycation’. In 2008 we met both Wall-E and Benjamin Button, were enthralled by the Beijing Olympics, and became addicted to Breaking Bad. And lest we forget, 2008 was also the year in which Beyoncé brought us Single Ladies; in all its sassy hand-waving, monochrome glory. For Crossref though, 2008 holds another important milestone as it was the year we launched our Similarity Check initiative. Today, the artist formerly known as CrossCheck provides our members with cost-effective access to Turnitin’s powerful text comparison tool, iThenticate.

New features, new indexing, new name - oh my!

TL;DR The indexing of Similarity Check users’ content into the shared full-text database is about to get a lot faster. Now we need members assistance in helping Turnitin (the company who own and operate the iThenticate plagiarism checking tool) to transition to a new method of indexing content.
