This section of the guide discusses various ways of demonstrating author impact:
Citation counts measure the impact of a particular publication or an individual author by counting the number of times either has been cited in other works. This analysis of a particular author's work is one of the components used to evaluate the quality of that's individual's scholarly output and the impact he or she is having upon a particular discipline. Although such counting sounds relatively straightforward, it is complicated by the fact that there is no single citation analysis source that covers all publications and their cited references.
There are a number of ways to measure this:
Citation analysis as a qualitative measurement should be used cautiously, for the following reasons:
Scopus and Web of Science offer tools for article benchmarking. Citation benchmarking indicates how citations received by the document being viewed compare with the average for similar documents.
Scopus citation benchmarking takes into account the date of publication, the document type, and the disciplines associated with the item. Citation Benchmarking compares documents within an 18 month window and is computed separately for each of its sources' disciplines.
In Web of Science, there are a few more steps to obtaining the baseline information. In the top navigation, look for Essential Science Indicators. Once in it, navigate to Field Baselines and Percentiles. Baselines are annualized expected citation rates for papers in a research field. Percentiles indicate how many citations it will take for a paper to be in the top 1%, 10%, 20%, 50% of papers in that field that year. For example, a 2017 material science article that received 18 citations would put that paper among the top 10% of papers published that year.
More information about Web of Science tools for author benchmarking can be found in Authors / Researchers: What is your impact? guide by Clarivate Analytics. Please note that the University Libraries does not currently have a subscription to the InCites section of Web of Science.
The FWCI score in Scopus indicates how the article's citation count compares to similar articles in the same field and timeframe.
A score of 1.00 is the "global average" and means the article is cited at an average level. Articles with a FWCI greater than 1.00 are performing better than global average. A FWCI below 1.00 suggests the article may be underperforming.
Important To Know
Because the FWCI comes from Scopus, only documents within the database (1996 to the present) will have a FWCI.
Because the FWCI includes field normalization, theoretically, the score should be a better indicator of performance than a raw citation count.
How to Find the FWCI
Locate the article in Scopus and go to its full record (Document Details). The FWCI is displayed within the Metrics area:
Along with citation data, many databases now display usage data for articles.The count reflects the number of times a user of that database has accessed the full text of or saved the article
For example, Web of Science displays usage for "Last 180 Days" and "Since 2013":
Scopus displays a variety of metrics in addition to citation data: usage in EBSCO databases, captures on sites such as CiteULike or Mendeley, as well as Wikipedia / social media references. These additional metrics are typically referred to as altmetrics or alternative metrics. Besides Scopus, PlumX Metrics are available on these platforms: EBSCOHost databases, EBSCO Discovery Service, ScienceDirect, Engineering Village.
Q: When looking for citation counts or h-index, is it better to use Web of Science, Scopus, or Google Scholar?
A: Since each indexes different content, it is a good idea to search all three, export the results into Refworks or other citation manager, and remove all duplicates. You may also want to consult discipline-specific databases that offer citation data.
Researchers should take steps to ensure that their online presence reflects their work and scholarly contribution by creating or reviewing their profiles in Scopus, Web of Science, and Google Scholar.
