Scientometrics and semantic maps for development (Author: Iina Hellsten)

  1. 1. Scientometrics & Semantic Maps for Development? Sarah Cummings (IKM) & Iina Hellsten (VU/Athena)
  2. 2. Context • How to map differences in the codification of knowledge management and/ or development? • Methods from scientometrics and bibliometrics, incl. citation, co-authorships and semantic map analysis • Project with Sarah Cummings
  3. 3. Introduction • What is scientometrics? • “science of science” since 1978 • uses bibliometrics to map publication behavior • origin in study of scientific publications • main applications: citation & co-authorship analysis • What are semantic maps? * multiple in the text analysis * can be applied beyond science * mapping implicit frames across actors / discourses (e.g. sciences, the mass media, policy documents…)
  4. 4. Citation analysis Idea: * scientific publications (with bibliographies) * author / article level: A. who cites whom B. which authors get most citations * journal level: which journals cite each others articles * citations across domains (Triple helix: patents – publications) Aim * view into discipline & specialty formation * A. changes over time & B. comparisons between disciplines, journals etc. * impact of the publications Limitations: * restricted to publications with list of references
  5. 5. Example of citation analysis: Development journals in 2007 Main journals (in Web of Science): 1) World Development 2) Development and Change 3) Journal of Development Studies Source: Loet Citation impact environment of World Development in 2007. Leydesdorff (1% threshold; cosine > 0.2)
  6. 6. Co-authorship analysis Idea: • Co-authorship networks, global and local; national and international • Who publishes with whom (disciplinary differences & development over time) • Co-authorships between university-industry-government (Triple Helix) Aim: • General view on dynamics of collaborations; inter- and transdisciplinary Limitations: * restricted to publications with list of references
  7. 7. Example of co-authorship analysis: Dutch authors in Development and Change Co-authorships of Dutch authors publishing in Development and Change, the core 30 co- authorships, 2005-2008
  8. 8. Semantic maps • Idea • Automated analysis of communications (texts) • Different levels of codification (e.g. science / mass media / policy / practice) • Aims * development of a debate over time (e.g. stem-cell research) * differences across discourses within one debate (such as the mass media vs. sciences vs. economics vs. policy-making) * differences in debates on the same topic across countries (U.S. vs. Europe vs. Asia / UK vs. Netherlands…) * …and would be able to detect emerging sub-debates (within stem-cell debate across the discourses and the countries)?
  9. 9. Comparing semantics? Leydesdorff & Hellsten, 2005, p.66
  10. 10. Example of semantic maps: “Millennium Development Goals” in Dutch newspapers “Millennium Development Goals in Dutch newspapers, 2005-2008 (69 news items)
  11. 11. Next steps • Semantic maps on scientific, journalistic, policy and practice documents (MDG debate) • Different topics of debate • Different level of codification • Citation and co-authorship analysis on industry-government-academia relations
  12. 12. Expected outcomes • Conference presentation: Towards Knowledge Democracy –conference (Leiden, 25-27 August, 2009) • Article(s)… • Discussion on new methodological avenues and their limitations
