  1. The uses, benefits and pitfalls of bibliometrics Julia Lane American Institutes for Research

  2. TO Describe Scientific Communication

  3. Outline • Context • Scientific Communication • Bibliometrics • Uses, Benefits and Pitfalls • Some other ideas and opportunities • What can be done

  4. Scientific Communication Knowledge • Creation • Transmission • Adoption

  5. 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 Source: http://en.wikipedia.org/wiki/Open_access_journal accessed May 26, 2012

  7. Scientific Communication • Is about people

  8. 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

  9. Bibliometrics • Is about documents

  10. Benefits Benefits • Have focused attention on quantitative measures of impact • Attracted some smart people to think about hard problems • Identified some interesting patterns

  11. 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

  12. 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

  13. Illustrative Example

  14. Why Getting it Right Matters

  15. 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

  16. Conceptual Framework Source: Ian Foster University of Chicago

  17. 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

  18. New Ways of Communicating Knowledge

  19. Scientometrics 2.0: Toward new metrics of scholarly impact on the social Web by Jason Priem and Bradley M. Hemminger.First Monday, Volume 15, Number 7 - 5 July 2010http://firstmonday.org/htbin/cgiwrap/bin/ojs/index.php/fm/article/viewArticle/2874/

  20. New Data • Natural language processing (=> mine actual text and identify topics) • Information extraction to capture data on people and institutions

  21. What can be done • Build on current advances to develop and automatically extract de-duplicated cross-referenced database of • papers (and references) • Topics • People • Grants • publication venues • Institutions • Build a common data infrastructure • STAR METRICS

  22. 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
