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.
TL;DR We missed an error that led to resource resolution URLs of some 500,000+ records to be incorrectly updated. We have reverted the incorrect resolution URLs affected by this problem. And, we’re putting in place checks and changes in our processes to ensure this does not happen again.
How we got here Our technical support team was contacted in late June by Wiley about updating resolution URLs for their content. It’s a common request of our technical support team, one meant to make the URL update process more efficient, but this was a particularly large request.
Crossref Conversations is an audio blog we’re trying out that will cover various topics important to our community. This conversation is between colleagues Anna Tolwinska and Rosa Morais Clark, discussing how we can make research happen faster, with fewer hurdles, and how Crossref can help. Our members have been asking us how Crossref can support open science, and we have a few insights to share. So we invite you to have a listen.
We’ve just added to our input schema the ability to include affiliation information using ROR identifiers. Members who register content using XML can now include ROR IDs, and we’ll add the capability to our manual content registration form, participation reports, and metadata retrieval APIs in the near future. And we are inviting members to a Crossref/ROR webinar on 29th September at 3pm UTC.
The background We’ve been working on the Research Organization Registry (ROR) as a community initiative for the last few years.
Cited-by gives our members full access to citations, helping them to build a picture of how research has been received by the community.
Scholars use citations to critique and build on existing research, acknowledging the contributions of others. Members can include references in their metadata deposits which Crossref uses to create links between works that cite each other. The number of citations each work receives is visible to anyone through our public APIs. Through our Cited-by service, members who deposit references for their content can retrieve and display itemized lists of works that cite their own.
Members who use this service are helping readers to:
easily navigate to related research,
see how the work has been received by the wider community, and
explore how ideas evolve over time by highlighting connections between works.
Watch the introductory Cited-by animation in your language:
Cited-by begins with depositing references as part of the metadata records for your content. Learn more about depositing references.
A member registers content for a work, the citing paper. This metadata deposit includes the references list. Crossref automatically checks these references for matches to other registered content. If this is successful, a citation is created.
Crossref logs the citations and updates the citation counts for each work. You can retrieve citation counts through our public APIs. Members who deposit references can sign up for the Cited-by service to retrieve the full list of citing works (not just the count), and can display them on their website. Cited-by complements citation counts by allowing access to the detail of each citation, even in cases where members have have chosen to set their references to limited or closed.
Note that citations from Crossref may differ from those provided by other services because we only look for links between Crossref-registered works and use a different matching algorithm.
Obligations and fees for Cited-by
Participation in Cited-by is optional, but encouraged
There is no charge for Cited-by
You must include references when you register content in order to be eligible for Cited-by
You only retrieve Cited-by metadata for your own content.
Best practice for Cited-by
Because citations can happen at any time, Cited-by links must be kept up-to-date. Members should either check regularly for new citations or (if performing XML queries) set the alert attribute to true. This means the search will be saved in the system and you’ll get an alert when there is a new match.
Also in the metadata is the number of citations a work has received, under the tag "is-referenced-by-count".
However, to retrieve the full list of citations for your own works, you need to register for Cited-by. While anyone can use an API query to see the number of citations a work has received, through Cited-by the member who deposited the work can retrieve a list of citing DOIs. Details of the citing works can be displayed on your website alongside the article.
In addition, Cited-by users can receive callback notifications or emails informing them when one of their works has been cited.
