The University of ZagrebFaculty of Humanities and Social Sciences
Department of Information SciencesIvana Lučića 3, 10000 Zagreb, Croatia
The Future of Information Sciences, INFuture 2009, 4 – 6 November 2009.
Objectives of analysis
• Development of Information Science– Development of Information
Science paradigm – Alterations of dominant authors
in information science from 1978 to 2007
– New approach for understanding of scientific paradigm by bibliometric analysis
Approach to analysis: most cited authors
• empirical display of dominant authors within scientific paradigm: – empirical knowledge zone,– conceptual knowledge zone and – research front zone
• alterations of dominant authors across three time periods
• To display of most cited authors and publications in information systems, museology and information science.
Research subject
• biblometric analysis of doctoral dissertations in Information Science at Croatian Universities (1978-2007)– doctoral dissertations are
original scientific publications which are using up to date world key literature
Data about dissertation
• from 1978 to 2007 at Croatian universities 134 doctoral dissertations were done in seven different disciplines: – information systems: 53 – communicology: 22 – information science: 21 – librarianship: 20– museology: 9 – archivistics and documentation: 8 – lexicography: 1
Methodology
• Cluster analysis • Citation “half-life” • Communication zones based on nature
of citation usage :– empirical knowledge zone – research front zone – conceptual knowledge zone

Methodology
• analysis of relationships between authors in research and in conceptual knowledge zones indicates that it is possible to identify three different groups of authors:– Predecessors– Scholars– Researchers
The Most Cited Authors in Information Science Disciplines
The Most Cited Authors in Museology• The number of all cited authors in
museology is 1279:– There are 972, or 76% of authors that
are cited only once in museology– 51.9 % of documents are cited only
once– 22 of the most cited authors make only
1.7%• 22 authors hold 10.2% of citations from
overall number of cited documents in museology
• almost 1/5 of all multiple citations hold 1.7%, that is, 22 most cited authors
The Most Cited Authors in Information Science
• The number of cited autors in information science is 1770 – 80.8% of authors are cited only once– number of all documents (with or
without authors) cited only once is 62.9%.
– 32 of the most cited authors (1.8%) hold 7.7% of citations
• A small number of authors (1.8%) holds 1/6 of all multiple citations
The Most Cited Authors in Information Systems
• The number of all cited authors in information systems is 3662: – 2981 authors, or 81.4%, are cited
only once– 61.1% of documents are cited
only once– 31 most cited authors make only
0.8%
• So, 0.8% authors hold almost 1/6 of multiple citations
The Most Cited Authors in Information Science Disciplines• In three analyzed disciplines 90
authors hold 1/6 of all citation:– 50% of authors is “mutual”
• 44 authors are cited in two or three disciplines.
• Cited in other disciplines:– In museology: 4 out of 27 authors– In information science: 26 out of
32 authors – In information systems: 19 out of
31 authors
The presents of the most cited authors from museology, information science and information systems in all disciplines • In seven disciplines:
– 1 author (M. Tuđman)
• In five different disciplines:– 4 authors (N. J. Belkin, G. Salton,
T. Saračević, A. I. Mihajlov)
• In four different disciplines :– 7 authors (V. Anić, M. Kržak, D.
de S. Price, V. Srića, B. Težak, S. Tkalac, M. Žugaj)
Researchers, Scholars and Predecessors
in Museology, Information Science and Information Systems
Researchers, Scholars and Predecessors• According to the criteria of cited
literature obsolescence, and according to location in the cluster of cited authors, we recognize several groups of authors: – Predecessors
• authors that are continuously cited after double citation half-life
• define conceptual knowledge zone– Scholars
• the authors that are cited after the period of citation half-life and until the end of double period of citation half-life
• define conceptual knowledge zone– Researchers
• the most cited authors in the first half of citation half-life
• define research front
Predecessors
• In museology: – R. Horvat, M. Gorenc, I. Čejvan, Z. Z.
Strànský, I. Mirnik, A. Bauer
• In information science:– N. Chomsky, H. A. Simon, D. J. de S.
Price, W. D. Garvey, K. Katičić, P. D. Allison, G. Salton, J. S. Long, B. C. Brookes
• In information systems:– W. D. Garvey, G. Salton, S. Dobrenić, D.
Radošević, A. I. Mihajlov, A. V. Aho
Scholars• In museology:
– D. F. Cameron, L. Dobronić, J. Neustupný, O. Maruševski, W.E. Washburn
• In information science:– A. Bookstein, T. Saračević, N. Pravdić,
M. Tuđman, M. Kržak, Q. L. Burrell, L. Egghe, J. Martin, D. W. Allen, Y. S. Chen, V. Anić, N. J. Belkin, V. Srića, D. R. Cruickshank, R. Rousseau, H. Sackman, L. M. Stolurow, D. Boras, Z. Dovedan

Predecessors, Scholars and Researchers’ Key Publications
Predecessors, Scholars and Researchers’ Key Publications• An overview of key authors and
their publications can be presented according to several criteria, or combination of criteria, so far described as:– overview of most cited authors and their
publications according to disciplines– overview of most cited authors and their
publications according to periods– overview of most cited authors
according to location and authors’ role in scientific community: predecessors, scholars, researchers
– overview of most cited authors and their publications according to the number of disciplines in which they were cited

Instead of conclusion
• The task of this paper is to prepare possible methodology for the research of Information science development
• In our analysis of Information Science development we advocate several starting points:
Instead of conclusion
1. We demonstrate how it is possible to identify dominant field of scientific influence inside the scientific paradigm– empirical knowledge zone– conceptual knowledge zone– research knowledge zone
Instead of conclusion
2. We propose criteria for the recognition of several groups of authors, with different influence and roles in described zones:– Predecessors– Scholars– Researchers
Instead of conclusion
3. We use several criteria that can serve as a filter for data selection: a) citation of authors according to
disciplinesb) citation of authors and their
publications according to periodsc) classification of authors according to
location and role in scientific community • Predecessors• Scholars• Researchers
d) overview of authors and their publications according to the number of disciplines in which they are cited.
Instead of conclusion
• Suggested “filters” for data selections are not sufficient for qualitative analysis, but they limit data to a small number that can be processed by qualitative analysis
• Thank you• Questions?
