Researcher identifiers

You are here

What and why?

As a result of the exponential growth in the number of scientific publications, it becomes increasingly difficult to distinguish authors with the same surname or initials from one another. In order to avoid linking an author to the wrong publication, researcher identifiers have been created, with which authors can be uniquely identified. The unique identification numbers are very useful for researchers to create and maintain their bibliometric profile, regardless of their host institution. Identification numbers are also used for the profiling of researchers, the evaluation of financial applications and analyses of publications. Each of these identifiers operates globally and interdisciplinary. 

Below you can find an overview of the researcher identifiers that are most commonly used within Hasselt University:

ORCID  |  ResearcherID  |  Scopus Author ID  |  ResearchGate person ID  |  Manuals  |  Contact


Open Researcher and Contributor Identifier (ORCID) is an international non-profit system, managed by a consortium of universities, national libraries, research institutes and data repositories, with which scientific authors can identify themselves by using a unique identifier (ORCID ID). With an ORCID ID, researchers can merge their own research output from multiple databases into one research profile. This research profile provides, next to the possibility of registering 37 different types of research output (ranging from journal articles to dance performances), the opportunity to bundle information regarding a researcher’s education, affiliations and granted financing. In this way it becomes possible to find information on a researcher based on his/her unique identifier. The ORCID ID also drastically reduces the confusion that may occur when authors have similar names, because names are sometimes not unique, may change over time and could be spelled differently depending on which database you consult. In other words, an ORCID profile provides you a complete list of information on an author’s academic career. It unites all scientific output of one researcher into one profile without ambiguity.


Clarivate provides its own researcher identifier within Web of Science, called the ResearcherID. This ResearcherID is compatible and interoperable with ORCID ID. 

Scopus Author ID

Elsevier provides its own researcher identifier within Scopus, called the Scopus Author ID. This Scopus Author ID is also compatible and interoperable with ORCID ID. 

ResearchGate person ID

ResearchGate is an online social network where authors of scientific publications can create a ResearchGate person ID. Through this platform they can share their publications, ask and answer questions and find potential collaborators. They can receive updates about the research from colleagues, who have looked at their publications, other researchers who follow publications within their research field, the most read articles, etc.

This FRIS platform has been created by the Flemish government with the intention to make Flemish research information publicly available.
