Personal identifiers (IDs)
IDs enable the system of large citation databases to automatically establish correspondences between a published work and its author, which makes it possible to quickly find information about publications and citations of a scientist, to view his/her publication profile, to specify a reference to the author's data in various documents, including grant applications for participation in competitions.
Open Research Contributor ID is a unique identification number assigned to a scientist within the framework of the project of an open non-profit organisation, whose work is aimed at creating and maintaining a register of unique identifiers of researchers. The uniqueness of the registry lies in its independence from national boundaries and scientific disciplines. Its main task is to solve the problem of identifying scientists with matching first and last names and to establish a link between researchers and their work.
Researcher Identification is an international identification system for creating a unique researcher profile containing information about their scientific publications and their history. Currently owned by Clarivate.
