Checking for originality: Crossref Similarity Check

  1. 1. Checking for originality: Crossref Similarity Check
  2. 2. What is Similarity Check? • Not plagiarism detection • It is a similarity screening service that uses the iThenticate text comparison software that was developed by Turnitin • What are papers checked against? • 59.1 million items from 1,271 Crossref organizations participating in the service (over 1,500 distinct members) • 105 million items from other content partners like Pearson, McGraw Hill, Cengage, EBSCOHost • Over 60 billion web pages archived back nearly a decade • Then provides a report for editors to evaluate
  3. 3. Good and growing adoption Total number of manuscripts scanned in iThenticate between 1st Oct 2016 - 1 Oct 2017 was 4,720,098
  4. 4. Setting up the service • Must be registering content and assigning DOIs in order to start using the service • Content must be indexed to be added to the Turnitin database • Indexing is done via as-crawled URLs. These must be present in your Crossref DOI deposit metadata • Function to deposit as-crawled URLs available in OJS 2.4.7 and above
  5. 5. What are as-crawled URLs? • Link used by Turnitin’s crawler service to identify and index the content associated with your DOIs • The as-crawled URL points the location of the full- text content, either PDF or HTML, associated with the DOI. • New DOIs the URL an be included as part the deposit metadata • Existing DOIs maybe updated
  6. 6. Similarity report
  7. 7. What issues are publishers looking for • Poor, missing, or incomplete references (can be fixed) • Self-plagiarism/text recycling (can be fixed) • Unattributed use of parts of another person’s work • Submitting another person’s work as your own • Is the author attempting to mislead/misrepresent?
  8. 8. How are people using it? Publishers putting time and effort into their policies and workflows: • Resources (staff & time) • Cost • Workflow • What will you look for & how will you look for it? • Education • Follow-up actions
  9. 9. Cost • Administrative fee = 20% of Crossref member fee • Document checking fees paid annually to Turnitin • Each publisher has their own login • More cost effective than joining Turnitin directly
