A Web of Science ResearcherID is a unique identifier that connects an author with his or her Works across the Web of Science ecosystem (Web of Science, Publons, and InCites).
The Researcher ID is now integrated in the Publons platform. Publons is a platform that records, verifies, and showcases peer reviewed contributions of researchers.
Information stored on Publons automatically integrates with Web of Science and data imported from ORCID, as well as your reference manager (Mendeley) and manual uploads, allowing you to track citations to your research outputs and know your h-index.
Each author can set their researcher ID profile privacy settings as they see fit.
