• Scientific Communication
• Bibliometrics
• Uses, Benefits and Pitfalls
• Some other ideas and opportunities
• What can be done
SCIENTIFIC COMMUNICATION
Knowledge
• Creation
• Transmission
• Adoption
OPEN ACCESS CONTEXT
• Authors: of such articles, who will see their papers more read,
more cited, and better integrated into the structure of science
• Academic readers: in general at institutions that cannot afford
the journal, or where the journal is out of scope
• Researchers: at smaller institutions, where their library cannot
afford the journal
• Readers: in general, who may be interested in the subject
matter
• The general public: who will have the opportunity to see
what scientific research is about
• Taxpayers: who will see the results of the research they pay for
• Patients: and those caring for them, who will be able to keep
abreast of medical research

SCIENTIFIC COMMUNICATION
• Is about people
BIBLIOMETRICS: USES
• …a set of methods to quantitatively analyze scientific
and technological literature..used.
• …in library and information sciences
• …to explore the impact of
• their field,
• a set of researchers, or
• a particular paper.
• …. in quantitative research assessment exercises of
academic output which is starting to threaten practice
based research
• Paraphrased from
http://en.wikipedia.org/wiki/Bibliometrics
BIBLIOMETRICS
• Is about documents
BENEFITS
Benefits
• Have focused attention on quantitative measures
of impact
• Attracted some smart people to think about hard
problems
• Identified some interesting patterns
PITFALLS
(ILLUSTRATIVE NOT EXHAUSTIVE)
Scientific validity
• Limited in its behavioral micro-foundations
• Based on suspect scientific frame (unit of analysis,
currency, coverage etc.)
• Not generalizable or replicable
Inferential validity
• Generates spurious results
• Subject to misuse and gaming
Value for evaluation
• Creates perverse incentive structure
ILLUSTRATIVE CRITICISM
Evaluators often rely on numerically–based shortcuts
drawn from the closely related fields (Hood and
Wilson, 2001) of bibliometrics and scientometrics — in
particular, Thompson Scientific’s Journal Impact
Factor (JIF). However, despite the popularity of this
measure, it is slow (Brody and Harnad, 2005); narrow
(Anderson, 2009); secretive and irreproducible
(Rosner, et al., 2007); open to gaming (Falagas and
Alexiou, 2008); and based on journals, not the articles
they contain.
Priem and Hemminger, 2010
ILLUSTRATIVE EXAMPLE
WHY GETTING IT RIGHT MATTERS
MEASURING COMMUNICATION:
SOME IDEAS AND OPPORTUNITIES
Focus on people (scientists)
• How to start a movement
Make use of scientific advances
• New theories (graph theory; RCT)
• New applications (social networks)
• New ways of communicating knowledge
• New application (graph oriented databases)
• New data (natural language processing; computational
linguistics)
New opportunities
=> Potential for new science, new scientific field and
theoretically grounded, metrics
CONCEPTUAL FRAMEWORK
Source: Ian Foster University of
Chicago
SCIENTIFIC ADVANCES
• Graph Theory applied to social networks
• E.g. Jason Owen Smith
• dyadic measures of the strength of individual ties;
• structural measures of cohesion in the overall network; and
• node demographic measures that highlight the degree of
heterogeneity of academic researchers
• Randomized Controlled Trials
• E.g John Willinsky
• Physicians
• Community Health Organizations

NEW DATA
• Natural language processing (=> mine actual text
and identify topics)
• Information extraction to capture data on people
and institutions
WHAT CAN BE DONE
• Build on current advances to develop and
automatically extract de-duplicated crossreferenced database of
•
•
•
•
•
•
papers (and references)
Topics
People
Grants
publication venues
Institutions
• Build a common data infrastructure
• STAR METRICS
WHAT CAN BE DONE TO CREATE NEW
SCIENCE
• Agree on handful of people based metrics
• Engage social scientists to develop open and
transparent data and standardized measures
• Use them
