Disentangling the origin of chemical differences using GHOST

1. We Can Do It!
Bibliometrics as a Library Service
in Special Libraries
Bibliometrics and Research Assessment:
A Workshop for Librarians
and Information Professionals
May 21, 2015

2. Ease of access to citation data and a
(natural?) desire to reduce complex
evaluations to numbers has led to
“unreflected use of ready-made indicators
offered by the owners of bibliometric
databases”
Librarians are ideally situated in our
institutions to provide bibliometric
support in a sensible and reliable way
3. Agenda
Why and How Librarians
Examples from APL
(about APL)
Questions Answered
Tools Used
Development Areas and What’s Next
5. Domain knowledge
To be successful librarians we know a bit
about:
Scholarly communication
Information retrieval in our areas
Organization of information
Our organization’s research output (what
types, where it goes, etc)
6. Data
We license the databases
We know how to do good searches
We know how to manage citations
coming from searches
7. But probably need to add…
The specifics of which calculations to
use for what
And the experts do not agree!
Tool knowledge
How to go from a database to a network or
count
How to clean up database results
Visualizing the results
8. Ethics
What to measure and how
How to represent results so that they
are clear about what they tell you

11. Critical Contributions to Critical Challenges
We are committed to public
service and strive for
excellence in all we do
Our goal is to strengthen the nation
through transformative innovation
and trusted technical leadership
in national security and space
We collaborate across
the University in
areas of national
importance

14. Sample Questions
In <research area>, do University
Affiliated Research Centers collaborate
more internationally than government
labs?
Define the research area (reference
interview! Discussion with local domain
expert)
Search domain databases (Inspec &
Compendex)
Co-authorship networks
Keyword – Country and Institution graphs
Check with domain experts

17. Given these records (unicode csv file of
unknown origin), what can we say about
the country’s published research in <this
large area>?
Who are the primary researchers?
What are the primary institutions?
How much collaboration is there among
institutions and internationally?
What methods are associated with
<terms>?
What are the trends over time?
18. Collaboration at APL:
What is the level of collaboration among
departments?
Has <intervention> changed collaboration?
19. Tools Used
Sci2
VantagePoint*
UCInet/NetDraw*
iGraph in R
Pajek
Inspire**
Note: NodeXL is also very good, but I am unable to install it at
work. YMMV. I have also used Sitkis, BibExcel, CiteSpace… and
maybe others!
* Licensed ($)
** Only available to government or for government contract work, I think
20. Takeaways
Librarians can and should leverage their
information science, subject, and
organization knowledge to support
bibliometric activities
There are many interesting and
important questions to answer
Additional training, self study, and
experimentation might be required (start
now!)
