Research Impact: Author Identifiers

Author Identifiers - Distinguish Yourself

Author identifiers are useful to help with author name disambiguation. In order to measure your impact as an author, you want to be sure you get credit for all your research output. By having an author identifier, it will help to connect your research outputs which you could have published under variations of your name, or different institutions, to you, instead of your work being incorrectly associated with another author.

Commonly Used Researcher IDs


ORCID is a unique and persistent digital identifier which allows you to distinguish yourself from other researchers, specifically those who have the same names or initials as you. Unlike Web of Science and Scopus, ORCID profile is not tied to a particular citation index database. ORCID can be synchronised with Web of Science and Scopus to update your profile automatically.

For more information on how to register, authorise NTU and to optimise your ORCID record, see this link.


Publons (ResearcherID)

You would need to register to Publons to get a ResearcherID, then populate it with the publications. Publons previously allowed authors to showcase their peer review and editorial contributions, but since being purchased by Clarivate Analytics and integrated with ResearcherID and Web of Science, it now also allows authors to link their publication activity as well.


Scopus Author ID

Scopus assigns each author with a unique Author Identifier (Author ID) and automatically groups publications by the same author under the Author ID. This automatic population comes with its pros and cons as duplicates of author IDs can occur (e.g. change of affiliations by researchers over time, researchers using different name variants for different publications).

Google Scholar Profile

Authors can create their own Google Scholar Profile, a free service provided by Google. Once you have created your Profile, you can populate the Profile with publications. You can check who is citing your articles, graph citations over time, and compute several citation metrics. You can make your profile public, so that it may appear in Google Scholar results when people search for your name, e.g., Richard Feynman.
