Social network analysis: a powerful strategy, also for the information sciences
The growth of SNA is documented and a co-author network of S NA is drawn, and centrality measures of the SNA network are calculated.
The R- and AR-indices: Complementing the h-index
The R- and AR-indices are introduced and it is proposed the pair (h, AR) as a meaningful indicator for research evaluation and a relation characterizing the h-index in the power law model is proved.
Requirements for a cocitation similarity measure, with special reference to Pearson's correlation coefficient
It is concluded that Pearson's r is probably not an optimal choice of a similarity measure in ACA and further empirical research is needed to show if, and in that case to what extent, the use of similarity measures in ACA that fulfill these requirements would lead to objectively better results In full-scale studies.
Similarity measures in scientometric research: The Jaccard index versus Salton's cosine formula
Sitations: an exploratory study
- R. Rousseau
We investigate the distribution of domain names and the distribution of links between web sites. It is shown that the Lotka function provides an adequate description. The percentage of self-sitations…
An informetric model for the Hirsch-index
It is shown that in each practical situation an IPP always has a unique h-index, which is based on the total number of items in Lotkaian systems.
Introduction to Informetrics: Quantitative Methods in Library, Documentation and Information Science
This chapter discusses informetric models, the dual approach between sources and items giving rise to the definition of Information Production Processes, and some science policy applications.
Diversity of references as an indicator of the interdisciplinarity of journals: Taking similarity between subject fields into account
The often‐heard argument, namely, that interdisciplinary research exhibits larger visibility and impact, is studied on the basis of these selected journals, yet, as only 7 journals are studied, albeit chosen to cover a large range of interdisciplinarity, further research is still needed.
Mapping collaborative knowledge production in China using patent co-inventorships
Examination of geographic variations in intraregional, inter-regional and international knowledge exchanges of China from 1985 to 2007 shows that a strong knowledge transfer network would much improve the innovation capacities in less favored regions and help them break out from their “locked-in” development trajectories.
