Thank you to everyone who responded with feedback on the Op Cit proposal. This post clarifies, defends, and amends the original proposal in light of the responses that have been sent. We have endeavoured to respond to every point that was raised, either here or in the document comments themselves.
We strongly prefer for this to be developed in collaboration with CLOCKSS, LOCKSS, and/or Portico, i.e. through established preservation services that already have existing arrangements in place, are properly funded, and understand the problem space.
I’m pleased to share the 2023 board election slate. Crossref’s Nominating Committee received 87 submissions from members worldwide to fill seven open board seats.
We maintain a balance of eight large member seats and eight small member seats. A member’s size is determined based on the membership fee tier they pay. We look at how our total revenue is generated across the membership tiers and split it down the middle. Like last year, about half of our revenue came from members in the tiers $0 - $1,650, and the other half came from members in tiers $3,900 - $50,000.
Crossref acquires Retraction Watch data and opens it for the scientific community Agreement to combine and publicly distribute data about tens of thousands of retracted research papers, and grow the service together
12th September 2023 —– The Center for Scientific Integrity, the organisation behind the Retraction Watch blog and database, and Crossref, the global infrastructure underpinning research communications, both not-for-profits, announced today that the Retraction Watch database has been acquired by Crossref and made a public resource.
Today, we are announcing a long-term plan to deprecate the Open Funder Registry. For some time, we have understood that there is significant overlap between the Funder Registry and the Research Organization Registry (ROR), and funders and publishers have been asking us whether they should use Funder IDs or ROR IDs to identify funders. It has therefore become clear that merging the two registries will make workflows more efficient and less confusing for all concerned.
To work out which version you’re on, take a look at the website address that you use to access iThenticate. If you go to ithenticate.com then you are using v1. If you use a bespoke URL, https://crossref-[your member ID].turnitin.com/ then you are using v2.
The Folders page contains the main functionality of iThenticate, the service which powers Crossref Similarity Check. It is where folders are created, browsed and shared with other users, where documents are submitted within a folder to be checked against the iThenticate database for similarity, and where documents can be deleted or moved from one folder to another.
Use the relevant tick boxes to exclude quotes, bibliography, certain phrases (set these under Account Info), small matches, and small sources.
To exclude small matches, you set an exclusion threshold. Any match with fewer words than the threshold will be excluded from the Similarity Check. This affects the Match Overview view in Document Viewer. Modify this option from within Document Viewer.
To exclude small sources, you set a word count or a percentage exclusion threshold. Any matches with fewer words, or lower than a certain percentage matched will be excluded from the Similarity Check. This affects the All Sources view in Document Viewer. Modify this option from within Document Viewer.
Think carefully about using percentage thresholds if you are working with large documents, where a set percentage of 1% may exclude very large matches/sources. For example, 1% of a 100-page document is one full page.
The exclude sections option allows you to exclude longer abstracts or methods and materials sections from being picked up by the Similarity Check.
Please be aware that section exclusion may not work properly if documents contain:
Unevenly spaced line numbering
Sub-headings that are indistinguishable from the Methods and Materials heading
Abstract or Methods and Materials section appearing within a table
Section headings and body text using the same font, font size, and font treatment
Repositories to search against (v1)
Choose which collections to include in the Similarity Check. Here are the currently available repositories:
Crossref - research articles, books, and conference proceedings provided by publishers of scholarly content all over the world
Crossref posted content - preprints, eprints, working papers, reports, dissertations, and many other types of content that has not been formally published but has been registered with Crossref
Internet - a database of archived and live publicly-available web pages, including billions of pages of existing content, and with tens of thousands of new pages added each day
Publications - third-party periodical, journal, and publication content including many major professional journals, periodicals, and business publications
To buy the option to create a customizable database source with your own content to submit to and search against, please contact firstname.lastname@example.org.
Save your new folder (v1)
Once you are satisfied with the changes you’ve made, click Create at the bottom of the form to create your new folder.
Create a new folder group (v1)
Start from the New folder section to the right of the page, and click New Folder Group.
On the Create A New Folder Group screen, name your new folder group, and click Create.
Now you have an empty folder group. To add a folder to this folder group, click Create a folder. To delete an empty folder group, click Remove this empty group.
Organize folders (v1)
Folders in the folder group are shown in alphabetical order. To see a folder group’s content, go to the My Folders section on the left, and click My Folders.
You can choose to organize the folders within a folder group by title, or by date processed:
To sort the folders by title, click the Title header in the title column. A down arrow shows that the folders have been arranged in alphabetical order. Click the down arrow again to put the folders in reverse alphabetical order.
To sort the folders by date created, click the Date Created header in the date created column. A down arrow shows that the folders have been arranged by date created, with the most recent first (reverse chronological order). Click the down arrow again to put the folders in chronological order.
Move folders (v1)
To move folders to another folder group, go to the folder group containing the folders you wish to move. Click the tick box beside the folder you want to move. From the drop-down menu, use Move selected to… to choose the destination folder group, and click Move.
The drop-down menu will not show unless you have created other folders to make it possible to move a document.
Delete folders (v1)
Start from the My Folders side menu, and hover over the folder you wish to delete. Click the trash can icon to move the folder to the Trash folder group.
To delete multiple folders, go to the folder group, and check the tick boxes for each folder you wish to delete. Click Trash in the menu bar above to move the folders to the Trash folder group.
Once a folder has been moved to the trash, you can review it before you delete it permanently. From the My Folders menu on the left, click the Trash folder group. In the trash, you can see all the folders you have moved here. To remove a folder from the trash, check its tick box, and use Move selected to… to move the folder to another location.
To permanently delete a folder, check its tick box, and click Delete in the menu bar above. Once you have permanently deleted a folder from Trash, you will not be able to get it back.
Share folders (v1)
Depending on how your account administrator has set up sharing permissions, you may be able to (a) view only folders shared by other users, (b) view all users’ folders, or (c) view folders of selected users. If you cannot automatically view others’ folders, use the sharing feature to share folders with other users within the same account.
Start from the folder you want to share, and click the Sharing tab.
You will see a list of users with whom you can share the folder. Check the box next to the users’ names, and click Update Sharing.
Sharing a folder with another user allows them to view the Similarity Report only. It does not allow them to submit a document to the folder.
Once a folder has been shared, there are two ways to unshare the folder:
by the user who shared it: uncheck the box next to the user’s name, and click Update Sharing
by the user with whom it is being shared: in the user’s directory, hover the cursor over the folder name, and an X icon will appear to the right of the folder name. Click the X icon to remove the shared folder.
Account administrators can enable or disable sharing access based on the organization’s internal guidelines. If the sharing feature is disabled, users will not be able to view previously shared documents.
Edit folder settings (v1)
To customize a folder’s settings, use the Settings tab within the folder. Folder settings includes three tabs: Folder Options, Report Filters, and Phrase Exclusions.
Use Folder Options to view and modify the options you chose when you created the folder.
Use Report Filters to manage the list of URLs that are filtered out from comparison checking for that folder.
Use Add URL to add a URL to be filtered, and click Add URL. The URL you add may be as specific or general as you wish, for example:
http://example.com/ (don’t forget to include the trailing “/”) - to exclude an entire site
http://example.com/docs/ - to exclude a specific directory
http://example.com/docs/paper.pdf - to exclude a specific document
To remove a URL, click the X icon to the right of the URL.
Use Phrase Exclusions to add and remove phrases to exclude from comparison checking for every submission in this folder. To add a new phrase, click Add a new phrase, enter the phrase you wish to exclude in the Phrase text box, and click Create. If you don’t want to create a phrase to exclude, click Back to list to return to the Phrase Exclusions tab, or Back to folder to return to the folder view.
Automatic exclusion of bibliography sections (v1)
iThenticate detects the following keywords and ignores any matches after the keyword:
reference cited, references cited
reference and note, reference and notes
references and note, references and notes
reference & note, references & note
reference & notes, references & notes
references and further reading
works cited, work cited
When it reaches any of the following words in the paper, it resumes the Similarity Check:
Automatic exclusion of quotations (v1)
Supported marks: iThenticate recognizes these quotation marks and will ignore any matches that use them:
Unsupported marks: iThenticate does not recognize these quotation marks and will flag any matches that use them:
This applies even when (single) ‘quotes’ appear within (double) “quotes”. For example:
“This text would be excluded ‘but this text would not be excluded’ “then this text would also be excluded.”
iThenticate will also exclude formatted block quotations (indented blocks of text) in .doc or .docx files.
