Making a Grope for an Understanding of Taiwan’s Scientific Performance through the Use of Quantified Indicators Prof. Dr. Hsien-Chun Meng Science and Technology Information Center (STIC) National Science Council 2002/12/
Outline • Research Background • Research Goals • Methodology • Results & Discussion • Future Works • References
Research Background • Insufficient bibliometric indicators to evaluate scientific research performance in Taiwan • Limited inquiry function of NSI and JCR • Lack of international comparison of the performance with benchmarking countries • STIC has aggressively involved in evaluating scientific activities
Research questions… • Is Taiwan’s research performance world class? • Has the performance improved or deteriorated? • What are the relatively strong and weak fields?
Research Goals • To assess the position of Taiwan’s S&T research system in an international comparative perspective • To identify relative strengths and weaknesses of scientific fields • To serve as a reference for technology policy formulation and for the future allocation of innovation resources
Methodology • Methodology : Bibliometric Method • Study Scope : • Time interval : 1995~2001 • Benchmarking Country Selection : • 7 advanced countries • 4 developing countries in Eastern Asia • CWTS Classification system : • 7 broad areas 43 fields
Advanced Countries United States of America Japan United Kingdom France Germany Netherlands Israel Developing Countries in Eastern Asia South Korea Peoples Republic of China Singapore Taiwan Benchmarking Country Selection
Bibliometric Indicators (1) • P: Publications • An indicator of scientific productivity and specialization of a country • Cx: Citations excluding self-cited • a frequently cited paper has had a greater influence on subsequent research activities • A measure of impact of research in the scientific community and recognition of scientific quality
Bibliometric Indicators (2) • CPPx: Average number of citations per publication (excluding self-cited) • CPPx/FCSm: normalized citation impact • FCSm: World citation average in the subfields • CPPx/FCSm score within the range of 0.8 and 1.2 is considered world average; above 1.2 indicates citation impact levels significantly above world average.
Data sources • ISI database • SCI (Science Citation Index) • SSCI (Social Sciences Citation Index) • AHCI (Arts & Humanities Citation Index) • Specialty Citation Indexes: “CompuMath”, “Biotechnology”, “Biochemistry”, “Chemistry”, “Materials Science”, “Neurosciences”
Overview of publication output • Country ranking in worldwide publication output (96’~01’)
Overview of publication output • Growth rates in total publication output

Future Works (1) • Micro level bibliometric analyses of Taiwanese science • Bibliometric data of 279 subfields in the period of 1995-2001 • Other bibliometric indicators are included: • CPPx/JCSm: compare the impact factor with the worldwide average in the same journal sets • JCSm/FCSm: to evaluate whether the country publishes in top journals • Breakdown of output (P) and impact (CPPx/FCSm) into ‘international collaboration’ and ‘national work’
Impact: Low Average High Example 1 Scientific Research Profile Output And Impact in Physics 1991 - 2000 Field (Impact Score= CPPx/FCSmx) *CPPx:The average numbers of citations per publication (excluding self-citations) *FCSmx:The average citation rate of all papers in the fields in which the group is active. *Impact Score (CPPx/FCSmx) within 0.8 and 1.2 is considered world average; scores above 1.2 indicates citation impact levels significantly above world average.
Impact: Low Average High Example 2 Scientific Research Profile Output And Impact in Physics 1991 - 2000 Field (Impact Score= JCSm/FCSm) *JCSmx:The average citation rate of all papers published in the ISI-covered journals in which a group has published. *FCSmx:The average citation rate of all papers in the fields in which the group is active. *Impact Score (JCSmx/FCSmx) within 0.8 and 1.2 is considered world average; scores above 1.2 indicates citation impact levels significantly above world average.
Future Works (2) • The research performance of Taiwan’s universities/institutions • 55 universities and 20 institutions are included • Breakdown of output and impact into scientific fields • International collaboration will be analyzed
