Who or what is Scopus?
Scopus is the Elsevier database of bibliometric data. Or in other words, it is a product operated by Elsevier and is known as largest abstract and citation database of research literature and quality web sources.
What document types are used to extract citations?
All.
Scopus offers articles, conference papers, reviews, letters , editorials, short surveys, articles in press, notes, erratum, books, conference reviews, dissertations and reports.
Are self-citations in- or excluded?
In 2011 self-citations are excluded for the first time.
Do you apply any time frame?
Data is drawn from Scopus for a five year window – in case of the 2011 QS World University Rankings that is 2006-2010.
Does the five year window refer to citations of papers published only from this period OR to citations for all recorded papers regardless of publication year?
The numbers relate to publications during the given period and citations for those papers during the same period. Or in other words, the 5 year period refers to BOTH the publication cycle AND the citation window. So, we collect data for all 5 years and citation counts within the same 5 year period.
Why do our own figures differ from those QS retrieved from Scopus?
Numbers may differ from those retrieved from Scopus as QS conducted additional mapping that aggregates multiple records and may retrieve more data. Additionally, Elsevier frequently adds records to Scopus and backfills for editions during the evaluated periods.
