Research impact metrics

Article citations count

With the citation counts metric, the underlying assumption is that the number of times a publication has been cited by other researchers reflects the influence or impact of a specific publication. The impact of an article is calculated based on the total number of times this document has been cited. 
 

You will need to select the database that provides adequate coverage of your work by checking :

• the number and the type publications covered ie. scholarly journals, trade journals, conference papers, book series
• the date ranges. i.e. some sources are not indexed or they are being indexed for a specific period of time. 

You can check (and compare) the impact of your publications in Scopus, Web of Science, Google Scholar, Crossref, Academia.edu, and ResearchGate. 
 

Normalized citations count

The number of citations is heavily influenced by both discipline and the time period used to collect data. To reduce bias for both these factors, methods have been introduced to normalize the citation impact of papers. Therefore, each citation is normalized according to subject and publication year. (See : Field-Weighted Citation Impact (FWCI), Citation Benchmarking or Percentiles).

 Scopus article metrics (Brought by UOB libraries)

Citation Count

• It shows how many times this publication has been cited.  

Field-Weighted Citation Impact (FWCI)

• It is the ratio of the document's citations to the average number of citations received by all similar documents over a three-year window.
• It shows how well cited this document is when compared to documents in similar subject field.
• A value greater than 1.00 means the document is more cited than expected according to the average.
• It takes into account: the year of publication, the document type, and the disciplines associated with its source.

Citation Benchmarking or Percentiles

• This metric shows how citations received by this article compare with the average for articles in the same field.
• 99th percentile is high, and indicates an article in the top 1% globally. 
• Citation benchmarking takes into account: the date of publication, the document type and disciplines associated with its source within an 18 month window.

PlumX Metrics

• It includes five categories of metrics : Citations (citation indexes, patent citations, clinical citations, policy citations), Usage (clicks, downloads, views, library holdings, video plays), Captures ( bookmarks, code forks, favorites, readers), Mentions (blog posts, comments, reviews, Wikipedia references, news media), and Social Media (shares, likes, comments, tweets).

Example of an article from Scopus

Open Scopus and search an article or subject. In the article page, you will find the metrics details. 

This article is cited in 1958 documents indexed in Scopus database. The FWCI is 20.20 which means that this article is very well cited in compare to documents in similar subject field.  The Citation Benchmarking shows a 99th percentile which means that this article is in the top 1% of documents in similar subject field.  PlumX Metrics indicate a total of 1350 of citations from multiple citation indexes,86 abstract views, 3 link-outs clicked from library catalogs, 512 readers added to personal libraries, 5 exports/saved, and 2 mentions in Wikipedia.

Google Scholar article citation (Free)

• Reflects the state of the web visible to Google search robots. Google scholar employs indexing algorithms aiming to identify bibliographic data or references in materials published on the web.
• Needs to be verified for accuracy as it often misidentifies or duplicates citations leading to artificial inflation of citation figures.

​Open Google Scholar and search an article or subject. In the results list, the number of citations the article has received is visible underneath each article ('Cited by'). Click on this number to see a list of all citations.
