Each scientific search platform has its own system to link publications to a specific author. The following instructions show you how to create author IDs and associated profiles. You can also use these IDs to calculate your h-index.
Web of Science - Publons
The Web of Science researcher identifier is called a ResearcherID. Within Web of Science, the ResearcherID can be used to look for publications by certain authors, like yourself. Having a ResearcherID is therefore good for the visibility and findability of your work. All ResearcherID profiles are shown on the Publons platform. Your Publons page lists your publications in Web of Science with their citation counts, and your h-index. Publons also lets you showcase your peer reviewing and journal editing history. Your profile metrics display both your publications/citations and peer reviewing activities. From your Publons profile, you can easily export your publications and activities to your ORCID.
Scopus automatically groups publications that have the same author, affiliation, and subject area. Every separate set of publications is assigned a Scopus Author Identifier. As such, you may have more than one Scopus Author Identifier. But, you can have Scopus merge these profiles into one. You can then use your Scopus Author Identifier to fill your ORCID or to calculate your h-index.
Google Scholar lets you create a profile to list all your publications. Google Scholar automatically assigns publications to your profile. You can manually add publications and remove publications that have been assigned incorrectly. Your h-index is also shown in your profile. This index is based on all your publications and citations in Google Scholar.
