Scopus

Scopus Citation Analytics

Scopus allows you to examine several citation metrics for the publications included in the Scopus database.

  • Journals: Scopus uses CiteScore, SJR, and SNIP scales along with other measurement scores to allow comparison between journals and other publications.
  • Authors: Using Scopus search functions and author evaluation tools, you can determine citation records and other impact factors for your own or other authors' publications.

Journal Analytics

Scopus allows researchers to analyze the journals contained in its database based on a variety of metrics on the "Analytics" page. Up to 10 journals can also be compared based on these same metrics in either chart or tabular form.

Journal metrics used include:

  • CiteScore: Counts the citations received in a year to documents published in the previous three years. This number is then divided by the number of documents indexed in Scopus published in those same three years. ‚ÄčDocument types used in numerator and denominator are the same and include research articles, reviews, conference proceedings, editorials, errata, letters and short surveys. CiteScore is not field-normalized and should not be used to be compared between disciplines. More info on CiteScore
  • SJR (SCImago Journal Rank): A journal "prestige metric" based on subject field, quality, and reputation of the journal. Uses the Google Page Rank algorithm and assigns relative scores to all sources in a citation network. Can be compared between disciplines. More info on SJR. 
  • SNIP (Source Normalized Impact per Paper): Considered a "popularity metric," SNIP is a weighted measure of contextual citation impact. It is calculated by diving the source's average citation count per paper and dividing it between the citation potential of its subject field. Can be used to compare between disciplines. More info on SNIP
  • Citations: the total number of citations a journal receives within a year
  • Documents: the total number of documents published by a journal within a year
  • Plus: Percent Not Cited (percent of documents published by the journal not cited to date) and Percent Reviews (percent of documents published by the journal each year that are review articles)

Author Analytics

Scopus allows researchers to analyze citation metrics on authors as well as specific articles by an author.

  • Author Search: Start by using the "Author Search" tab contained in the "Search" page to locate materials by the author of interest. The more detail you can provide regarding the author, the more precise your search will be, but last name and first initial and/or institutional affiliation are generally the minimum requirements. Scopus uses the "Scopus Author Identifier" to attempt to group documents by the same author, but be aware that a single author may be listed more than once depending on different forms of the name or a change in institutional affiliation. Once you select the correct author then you can use the analytic tools below.
  • Citation Overview: After you have completed the "Author Search", tick the box next to the author name(s) to select, and then click on "View citation overview" at the top of the list of names. This will show a table listing the documents by the author(s), and the number of times each article has been cited by year.
  • Analyze Author Output: After you have completed the "Author Search", click on the author's name to go into the author's details page. Next to the listing for "Documents" click on "Analyze Author Output." From here you can examine various aspects of the author's "Documents" including: sources (where published), document types, years of publication, subject areas and co-authors. Other tabs on this page include "Citations" offering a graph of the total number of citations by year of an author's published works and the "h Index" and h-graph (see below).
  • h-index: This measure is based on the number of the author's published works and the number of citations. The accompanying h-graph displays the "h Index" for an author, a group of authors or selected documents.

Institution

Scopus allows researchers to determine citation metrics by institution.

Affiliation Search: From the Search page click on the "Affiliation Search" tab. Enter the institution of interest in the search box and click search. If more than one institution returned, click on the result that is most appropriate. Results for each institution provide the percentage of publications in each of the covered subject areas, the total number of documents published by the institution, the total number of authors affiliated with the institution, journals and other sources of the documents, major collaborating affiliations of the institution, etc. You may further sort the documents, authors, web results, patent results, sources and affiliated institutions retrieved by clicking on the appropriate link.

Analyze Results

For any given search, once you have retrieved a list of documents, you can click the Analyze Results button in the top left corner of the results box.  A window will open with several tabs.  Each tab in the Analyze Results windown contains a set of graphical displays and charts that can be manipulated.  Search metrics are organized by Year, Source Title, Author name, Affiliation, Name Country, Document type and Subject area.  The graphics also offer contextual boxes that give insight on specific points along the curve.

Scopus Limitations
