Scopus

Scopus Citation Analytics

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

  • SNIP (Source Normalized Impact per Paper)
  • SJR (SCImago Journal Rank) indicator
  • H-index (Hirsch index)
  • CiteSource

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.

Click on Compare sources to compare up to 10 Scopus sources on a variety of parameters, including those outlined above. The journal analyzer includes data from 1996 to the current year. When citations are calculated for a source, documents published before 1996 are not included, because complete citation information for documents published prior to 1996 is not available in Scopus. The analyzer is available in both a line chart and a table view. The line chart displays information in a line graph, with separate graphs for each parameter. The table lists parameters together in one table.

More on CiteScore

CiteScore is another metric for measuring journal impact in Scopus. The calculation of CiteScore for the current year is based on the number of citations received by a journal in that year for the documents published in the journal in the past three years, divided by the documents indexed in Scopus published in those three years. This is how CiteScore of 2018 is calculated:​

Calculation of CiteScore in the Year 2018:

CiteScore in 2018 = No. of citations to all items published in 2015-2017
No. of all items published in 2015-2017

 

Note: CiteScore includes all document types indexed in Scopus, e.g. articles, reviews, letters, notes, editorials and conference papers.


CiteScore metrics are a family of 8 indicators, include: CiteScore, CiteScore Tracker, CiteScore Percentile, CiteScore Quartiles, CiteScore Rank, Citation Count, Document Count and Percentage Cited.

  • CiteScore Tracker provides a current review of how a journal is performing during the course of the year. It is updated every month.
  • CiteScore Percentile indicates how a journal ranks relative to other journals in the same subject field. (The fields are defined according to the Scopus field definitions).

More on SJR and SNIP

SJR (SCImago Journal Rank):

  • ranks publications by weighted citations per document.
  • is a prestige metric based on the idea that not all citations are the same. Citations are weighted more or weighted less – depending on the source they come from.
  • with SJR, subject field, quality and reputation of the journal have a direct effect on the value of a citation.
  • with SJR, self-citations are limited to the maximum of 33%.

SNIP (Source Normalized Impact per Paper):

  • measures contextual citation impact by weighting citations based on the total number of citations in a subject field. The impact of a single citation is given higher value in subject areas where citations are less likely, and vice versa. For example, journals in Mathematics, Engineering and Social Sciences tend to have higher values than titles in Life Sciences.
  • allows direct comparison of sources in different subject fields.
  • with SNIP, the differences of journals’ SNIP are due to the quality of the journals but not the different citation behavior between subject fields.
Use SJR ... Use SNIP ...
  • to enhance position of post-prestigious journals (SJR emphasizes the differences)
  • if focusing on Life and Health Sciences
  • if topicality is important in journal performance
  • if you want to weight citations based on the status of the citing journal
  • if value is less important than rank (SNIP reduces the differences)
  • if focusing on Engineering, Computer Science, and Social Sciences
  • if you are focused on subject field normalization
  • if you think that impact and topicality are separate and should be considered independently

Article Metrics

Example of Article Metrics

Article-level metrics (ALMs) quantify the reach and impact of published research. Scopus now integrates data from PlumX

Metrics as the primary source of its article-level metrics, along with traditional measures (such as citations), to present a richer and more comprehensive picture of an individual article’s impact.

The Article Metrics module can be found on Scopus in the Document details page, where a sidebar highlights Scopus citation count (along with percentile benchmarking), Field-weighted citation impact and PlumX Metrics. Clicking on “View all metrics” opens a more detailed Metrics page, displaying all available metrics and the underlying content for further analysis and understanding.

 

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.
  • Author Evaluator: 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 "View Author Evaluator." 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.

Affiliation Metrics

Scopus allows researchers to determine citation metrics by institution.

From the Search page click on the "Affiliation Search" option. 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.
