Why measure journal impact?
◦ Attempt to measure quality and prestige of
journals
◦ Note that it was not meant to evaluate
quality of the individual articles in the
journals

Journal Metrics: Journal Impact Factor
No. of cites received by articles published in 2013 & 2014, in year 2015
Total no. of citable articles from that journal in 2013 & 2014
2015
Impact
Factor

What does this number mean?
How frequently an average article in this journal has been cited in year 2015
Source of data?
Web of Science citation data
How to find this number?
Journal Citation Report (JCR) subscribed by SMU Libraries

How to access Journal Citation Report (JCR)
1. Go to SMU Libraries website (library.smu.edu.sg)
2. Click on Databases, search for ‘JCR’
3. Click on ‘Journal Citation Report’
4. Search for the journal title

JCR > Journal title search > Full record
Click on Psychology,

Also at http://journalmetrics.scopus.com [Free]
SCImago Journal Rank (SJR) expresses the average number of
weighted citations received in the selected year by the documents
published in the selected journal in the three previous years

How to find CiteScore & SJR in Scopus
1. Go to SMU Libraries website (library.smu.edu.sg)
2. Click on Databases, search for ‘Scopus’
3. Click on ‘Scopus’, click on “Sources”

Scopus > Sources > Journal title search

Journal Metrics > Subject area search

Things to Note
◦ You cannot compare impact factor/
CiteScore/SJR across different subject areas
◦ It gives you an idea about the quality of a
journal, but not the quality of an article

Comparison of Top Journals
◦ Academy of Management Journal
JIF = 6.233 | CiteScore = 8.71 | SJR = 10.317
◦ Journal of Finance
◦ Quarterly Journal of Economics
◦ Journal of Applied Psychology
◦ Political Analysis
◦ ACM Computing Surveys
◦ Nature

Types of Research Metrics
• Journal Impact Factor, CiteScore, SJR
Journal Metrics
• h-index, FWCI
Author Metrics
• Citation count, FWCI, Altmetrics
Article-level Metrics

Article-Level Metrics
ALMs measures the impact of individual articles
Citation Count
Can be found from a variety of sources: WOS, Scopus, Google Scholar.
Altmetrics
• A non-traditional metrics to capture influences outside academia
• Capture interest on social media, readership, discussions and so on
• Gives indication of immediate impact compared to citations
Field Weight Citation Impact (FWCI)
Can be found from a variety of sources: InCites, Scopus

What is FWCI?
◦ Field-Weighted Citation Impact (FWCI)
indicates how the number of citations
received by a publication compares with the
average number of citations received by all
other similar publications in the data
universe
◦ Where 1 is average and the higher the ratio
the better
◦ Normalised for Subject area (of journal),
Publication year, Document type
20

How to access WOS / Scopus / Google Scholar for
citation count
1. In the database, search for the article title

WOS > Article title search
Click on Times Cited
to see details of citing
articles

Scopus > Article title search
Scroll down the page to

including FWCI

GS > Article title search [http://scholar.google.com]

Altmetrics
Usage Data
• Clicks & page views
• Downloads
Discussions on
the open web
• Blog posts
• Comments, shares, likes in Facebook, Twitter, etc.
Interest in
reading/citing
the work
• Bookmarks, saves, subscriptions, citation exports
• Readership on citation managers such as
Mendeley - a good early indicator of future
citations

Altmetric in InK

AltMetric on Publisher website

Author Metrics
H-index measures both productivity and citation impact
If I have an h-index of 5, I have at least 5 publications that have been cited at
least 5 times.
Source of data?
H-index from different sources can be different!
Web of Science | Scopus | Google Scholar
Web of Science (Researcher ID)
Scopus (Scopus Author ID)
Google Scholar only if you have a Google Scholar Profile)

Author Metrics
Field Weighted Citation Impact
If I have an FWCI of 2, my impact is 200% better than average
for the same type of publications, same subject areas and
same publication years. [Note: Less reliable if < 20 publications]
Source of data?
This metric is calculated using
Web of Science / InCites | Scopus / SciVal
InCites for individual publications or authors or groups or
institutions
SciVal for authors or groups or institutions
