1Winnink, J.J. ; Tijssen, R.J.W. ; Raan, F.J. van: Theory-changing breakthroughs in science : the impact of research teamwork on scientific discoveries.
In: Journal of the Association for Information Science and Technology. 67(2016) no.5, S.1210-1223.
Abstract: We have developed and tested an evidence-based method for early-stage identification of scientific discoveries. Scholarly publications are analyzed to track and trace breakthrough processes as well as their impact on world science. The focus in this study is on the incremental discovery of the ubiquitin-mediated proteolytic system in the late 1970s by a small international team of collaborating researchers. Analysis of their groundbreaking research articles, all produced within a relatively short period of time, and the network of citing articles shows the cumulative effects of the intense collaboration within a small group of researchers working on the same subject. Using bibliographic data from the Web of Science database and the PATSTAT patents database in combination with expert opinions shows that these discoveries accumulated into a new technology. These first findings suggest that potential breakthrough discoveries can be identified at a relatively early stage by careful analysis of publication and citation patterns.

In: Journal of the American Society for Information Science and Technology. 63(2012) no.12, S.2405-2418.
Abstract: The Leiden Ranking 2011/2012 is a ranking of universities based on bibliometric indicators of publication output, citation impact, and scientific collaboration. The ranking includes 500 major universities from 41 different countries. This paper provides an extensive discussion of the Leiden Ranking 2011/2012. The ranking is compared with other global university rankings, in particular the Academic Ranking of World Universities (commonly known as the Shanghai Ranking) and the Times Higher Education World University Rankings. The comparison focuses on the methodological choices underlying the different rankings. Also, a detailed description is offered of the data collection methodology of the Leiden Ranking 2011/2012 and of the indicators used in the ranking. Various innovations in the Leiden Ranking 2011/2012 are presented. These innovations include (1) an indicator based on counting a university's highly cited publications, (2) indicators based on fractional rather than full counting of collaborative publications, (3) the possibility of excluding non-English language publications, and (4) the use of stability intervals. Finally, some comments are made on the interpretation of the ranking and a number of limitations of the ranking are pointed out.
3Tijssen, R.J.W.: Discarding the 'basic science/applied science' dichotomy : a knowledge utilization triangle classification system of research journals.
In: Journal of the American Society for Information Science and Technology. 61(2010) no.9, S.1842-1852.
Abstract: This paper introduces a comprehensive system for classifying scholarly journals according to their degree of 'application orientation.' The method extends earlier models and journal classification systems that were designed to tackle the crude duality between 'basic research' and 'applied research.' This metrics-based system rests on a 'Knowledge Utilization Triangle' typology, which distinguishes three types of coexisting knowledge application domains: 'clinical,' 'industrial,' and 'civic.' The empirical data relate to the institutional origin of authors who publish their research papers in the scientific journal literature. The case study applies indicators of 'clinical relevance' and 'industrial relevance' to 11,000 journals indexed by the Web of Science (WoS) database. The resulting multidimensional classification system of journals comprises six Journal Application Domain (JAD) categories. Macro-level trend analysis of the WoS-indexed research publication output by JAD category reveals redistributions within global science during the years 1999-2008, with a slight increase of output published in 'industrially relevant' journals.

In: Scientometrics. 42(1998) no.1, S.41-60.
Abstract: International bibliographic databases and related biblimetric indicators together provide an analytical framework and appropriate measure to cover both the 'supply side' - research capabilities and outputs - and 'demand side' - collaboration, diffusion and citation impact - related to information and communication technologies (ICT) research. Presents results of such a bibliometric study describing macro level features of this ICT knowledge base
