How is this computed?

h-index and citations are computed from the citation counts of this academic’s YÖKSİS articles matched in OpenAlex (not Google Scholar, WoS or Scopus). Unmatched articles are not included. 1 articles (0 citations) tagged with this academic’s YÖK author id in co-authors’ YÖKSİS records count only towards citations, h-index and i10; article counts, percentiles and rankings use their own YÖKSİS list.

Where does this list come from?

Extracted from the reference lists in Crossref’s public March 2026 data file; 20.3% of the file has been processed, so the list may be incomplete. Crossref citations are never added to or compared with the OpenAlex citation counts; the two sources have different coverage.
