Why DOI Records Matter for Publication Attribution
How persistent research-object identifiers help remove duplicates and support auditable impact calculations.
One work, many appearances
An article may appear as a publisher page, repository manuscript, indexing entry and institutional listing. If a platform counts every appearance as a separate publication, productivity statistics become inflated. Persistent identifiers can help connect manifestations of the same work.
DOI strengths and limits
A DOI often gives a stable way to retrieve publication metadata and establish a canonical object. However, not every scholarly output has a DOI, and DOI metadata may contain incomplete author details. The identifier alone cannot prove who controls a researcher profile.
Deduplication needs judgment
Exact DOI matches are strong evidence of duplicate records, while title similarity is less certain. Preprints and final articles may require an explicit version relationship instead of an indiscriminate merge. Corrections and retractions should remain visible.
For ranking accuracy
Inspect surprising publication counts and identify any duplicated versions or misattributed author names. Reliable output counting requires consistent identity rules, clear document types and a traceable record of what was admitted.
