DOI, ORCID and researcher identity: what each identifier actually does

DOIs and ORCID iDs are often shown next to each other on scholarly platforms, but they identify different things. A DOI normally identifies a research output such as an article, dataset or other registered object. An ORCID iD identifies a researcher. Connecting the two helps a platform answer both “what is this work?” and “which person is associated with it?” without relying only on text matching.

Names alone are fragile identifiers. Researchers can share the same name, publish under initials, change surnames or appear in different transliterations. A persistent person identifier reduces that ambiguity, while a persistent work identifier reduces ambiguity among publications.

Bibliographic feeds frequently contain author strings rather than verified people. A string such as “H. M. Muafa” may refer to a known researcher, but a platform should not silently assume identity from spelling alone. The safer approach is to treat the string as authorship evidence and strengthen the link using ORCID, verified account claims, affiliations and publication history.

This prevents two opposite errors: merging different people who happen to have similar names, and splitting one researcher into many profiles because different sources formatted the name differently.

ResearchHub separates the idea of an imported author record from a person who actively controls a profile. A claimed profile can be enriched with verified identifiers, biography, affiliations and researcher-selected information. An imported record is more limited and should remain clearly labelled until stronger identity evidence is available.

That distinction gives readers useful context and gives researchers a path to improve the accuracy of their public identity without pretending that every imported author string has already been verified as a person.

No single field should carry the full burden of identity verification. Reliable researcher identity is built from multiple consistent signals: persistent identifiers, publication relationships, institutional affiliations, direct claims and source provenance.

The practical benefit is a graph that is easier to search and harder to corrupt through accidental duplication. Better identity links also improve downstream features such as citation summaries, institutional analytics, recommendations and research discovery.
