1分快三骗局With editors under increased pressure to assess higher volumes of manuscript submissions each year, it’s important to find a fast, cost-effective solution that can fit seamlessly into your submission workflows. Similarity Check allows editors to upload a paper, and receive a report giving immediate feedback regarding a manuscript’s similarity to other published academic and general web content. And as the iThenticate database contains over 50 million full-text scholarly content items, editors can be confident that Similarity Check will provide a comprehensive and reliable addition to their workflow.
As members contribute their own published content into iThenticate’s database of full-text literature, the service is open to any Crossref member who is actively publishing and assigning Crossref DOIs to their journal article content.
1分快三骗局While there are several plagiarism screening tools available, Similarity Check participants enjoy cost-effective use of iThenticate because they contribute their own published content into Turnitin’s database of full-text literature. This means that as the number of participants grows, so too does the size of the database powering the service. More content in the database means greater peace of mind for editors looking to determine a manuscript’s originality.
Turnitin also provides our members with access to additional features in iThenticate, such as enhanced text-matches within the document viewer. And with access to Turnitin’s dedicated Similarity Check support team, our members always have a direct line to Turnitin in order to discuss any technical or billing queries.
1分快三骗局In return for a reduced fee for access to iThenticate, Similarity Check subscribers allow Turnitin to index their full catalogue of current and archival published content as this ensures the highest level of text-matching accuracy. This means that the service is only available to members who are actively publishing DOI-assigned content and including full-text URLs in their metadata which Turnitin can access.
Turnitin index members’ content directly via their Content Intake System. Their CIS accesses our metadata daily to collect the full-text content links provided by our members within their DOI deposit metadata. Turnitin follow these URLs and index the content found at each location.
On application to join the service, members must ensure they have full-text URLs present in the metadata of at least 90% of their registered articles (across all the member’s journal prefixes, as applicable). These URLs need to point directly to the full-text PDF, HTML or plain text content. Members must also ensure that these links are included in all future deposits too.
Please note that the metadata which members deposit with Crossref is available to be searched and retrieved by everyone, and this includes Similarity Check URLs. If your content is paywalled, please make sure that your Similarity Check URLs prompt an authentication step before allowing a user to access full-text content. You’ll need to ensure that your hosting provider has to ensure the content is accessible for Turnitin to index.
1分快三骗局Once members meet the eligibility criteria for Similarity Check, members will be provided with access to iThenticate. Using iThenticate, members will be able to upload their own manuscripts to compare against the full corpus of published academic and general web content in Turnitin’s database. iThenticate provides a similarity score and a highlighted set of matches to similar text. Editors can then further review matches in order to make their own decision regarding a manuscript’s originality.
