- | **Vrelci in brezna v usmerjenih omrežjih** | + | **Analyzing bibliometric networks: Tools, techniques, and applications** |
- | Pred kratkim sem naletel na članka http://arxiv.org/abs/1005.2179 in | + | Bibliometric networks are networks of, for instance, scientific |
- | http://www.springerlink.com/content/5701377033448410/ , v katerih | + | publications, journals, or authors connected by citation or |
- | avtorji vpeljejo pojma vrelca (volcano) in brezna (blackhole) ter | + | co-authorship links. Other popular bibliometric networks are |
- | podajo nekaj algoritmov za njih določitev. | + | networks of words or terms extracted from scientific publications |
- | + | and connected by co-occurrence links. | |
- | Na seminarju si bomo na kratko ogledali oba članka, ki ju bom | + | In this talk, I will give an overview of the research program |
- | razširil s svojimi razmišljanji in zamislijo alternativnega | + | into bibliometric network analysis at the Centre for Science and |
- | algoritma. | + | Technology Studies (CWTS) of Leiden University. I will introduce |
- | http://vlado.fmf.uni-lj.si/vlado/papers/Euler.pdf | + | two software tools developed at CWTS for analyzing bibliometric |
+ | networks: VOSviewer (www.vosviewer.com) and CitNetExplorer | ||
+ | (www.citnetexplorer.nl). I will also discuss some of the techniques | ||
+ | used in these tools, in particular the unified approach to network | ||
+ | layout and network clustering and the smart local moving algorithm | ||
+ | for optimizing clustering quality functions. Finally, I will show | ||
+ | some practical applications of bibliometric network analysis in the | ||
+ | context of research planning and research evaluation, and I will | ||
+ | discuss a number of important open research problems. | ||
