1 Welcome to the International Workshop on Webometrics, Informetrics and Scientometrics & Seventh COLLNET Meeting 10-12 May, 2006 INIST-LORIA-Nancy

2 The main mission of LORIA is the fundamental and supplied research in the field of information and communication technologies. LORIA plays also a strategic role in the training of young researchers, in partnership with Universities and in the technology transfer via partnerships with industry and support in the creation of start-up companies The institute for Scientific and Technical Information (INIST) is a service unit of the French National Center for Scientific Research (CNRS). Its mission is to collect, analyze and disseminate the results and findings of worldwide research in science, technology, medicine, humanities, economics and social sciences.

6 COLLNET The outstanding works of Donald deB Beaver, Derek John de Solla Price and others on the theme of collaboration in science have been inspiring many over several decades to devote themselves to research in this area. Welcome to Donald deB. Beaver: First Invited Plenary Talk

7 COLLNET is a global interdisciplinary research network under the Title „Collaboration in Science and in Technology“ Since foundation in 2000 six COLLNET Meetings were already held in conjunction with international conferences or workshops on science studies. COLLNET cordially thanks INIST and LORIA for invitation to organize the 7th COLLNET Meeting here in the beautiful Nancy! Why in Nancy? Decision at the 5th COLLNET Meeting in Roorkee, India

8 The focus of COLLNET is to examine the phenomena of collaboration in science, its effect on productivity, innovation and quality, and the benefits and outcomes accruing to individuals, institutions and nations of collaborative work and co-authorship in science. On account of the diversity of these issues it is possible to obtain promising results only against the backdrop of an interdisciplinary approach and from an intercultural viewpoint including both developing and developed countries. COLLNET was founded in 2000 in Berlin by three scientists from China, India and Germany. In 2006 there are about 80 members from more than 20 countries of all continents (about 30% are ISSI members).

16 A New Centrality Measure for Social Network Analysis Applicable to Bibliometric and Webometric Data Kretschmer, H.& T. Kretschmer: In the literature there are a large number of publications in sociology, in computer science or in information sciences, as well as in studies of collaboration in science describing the studies of social networks with unweighted ties because measures involving unweighted ties are easier to calculate. It is not surprising that there are few studies on networks with weighted ties since they not only need more complex formulas but need a process of quantification when quantitative empirical data are not directly available. However quantitative empirical data are directly available under the condition of using bibliometric or webometric data. In conclusion new complex measures of the degree centrality are introduced including weighted ties possible for use of the analysis of co-authorship or citation networks. Both co-authorship relations and citations are well quantified data (weighted ties). These new measures are applied to a co-authorship network as an example.

18 The Complex Measure of Degree Centrality CDCA of a node A is equal to the geometric mean of the “number” of nodes to which this node is connected and the total strength of the ties. The “number” is calculated as the transformed entropy of the weights. The Complex Group Degree Centralization measure is proposed describing the dispersion in a connected graph.

Department of Library and Information Science, Humboldt-University Berlin, Dorotheenstr. 26, D-10099 Berlin, Germany; 4. Department of Sociology, University of California - Riverside, USA Abstract By mapping the electronic database containing all publications in Scientometrics for a 26-year period (1978-2004), we uncover the topological measures that characterize the network as a whole, as well as the time evolution of these quantities. The results indicate that the network is scale-free with exponent αcite=1.9977, and shows small-world feature with mean geodesic distance less than 4.
