The ORCID iD: a unique, persistent identifier free of charge to researchers. Open Researcher and Contributor ID is a nonproprietary alphanumeric code to uniquely identify authors and contributors of scholarly communication.
This addresses the problem that a particular author's contributions to the scientific literature or publications can be hard to recognize as most personal names are not unique, they can change (such as with marriage), have cultural differences in name order, contain inconsistent use of first -name abbreviations and employ different writing systems.
Scopus Author Profile
Each Scopus Author Profile is a unique record of that researcher’s publication activity. The details come from peer-reviewed articles and other publications that are indexed in Scopus (published in journals, books and other sources, that the Scopus Content Selection and Advisory Board has selected for inclusion and indexing) where the researcher is specified as an author. The information in a profile includes the author name, affiliation(s), subject area(s), publications, citations, and co-authors. The profiles do not cover editorship, managerial or executive roles, or teaching positions.
ResearcherID / Publons
The identifier consists of alphanumeric characters and includes the year in which the user was registered. The service presents the researcher's public profile (linked to Web of Science), his or her e-mail, affiliation and research interests, list of publications, and allows data correction, citation count and Hirsch index monitoring.
In 2019, all ResearcherID accounts marked as 'public' have been transferred (along with their existing content) to the Publons platform. The existing ResearcherID ID numbers and login details remain unchanged, and any links leading to the ResearcherID profile automatically redirect to the relevant page on the Publons platform.
Publons presents information about publications, citations and reviews by researchers in one place. It is associated with the Web of Science database, the ORCID system and thousands of scientific journals, so that publications from different resources can be automatically imported or updated.
A tool that allows users to create and manage their own scientific profile. These profiles are compiled from publications and other scientific data available on Google Scholar. Users can make their profile public, so that it may appear in Google Scholar results when people search for their name.
