Evaluation of research activities of universities of Ukraine and Belarus: a set of bibliometric indicators and its implementation Vladimir Lazarev, Serhii Nazarovets and Alexey Skalaban Monitoring bibliometric indicators of University rankings is considered as a subject of a University library activity. In order to fulfill comparative assessment of research activities of the universities of Ukr...
OBJECTIVES To perform a bibliometric analysis of theses and dissertations on prematurity in the Capes database from 1987 to 2009. METHODS This is a descriptive study that used the bibliometric approach for the production of indicators of scientific production. Operationally, the methodology was developed in four steps: 1) construction of the theoretical framework; 2) data collection sourced f...
OBJECTIVE We have carried out a bibliometric study on the scientific publications in relation to atypical or second-generation antipsychotic drugs (SGAs) in South Korea. METHODS With the EMBASE and MEDLINE databases, we selected those publications made in South Korea whose title included the descriptors atypic(*) (atypical(*)) antipsychotic(*), second-generation antipsychotic(*), clozapine, r...
In November 2012 the Google Scholar Metrics (GSM) journal rankings were updated, making it possible to compare bibliometric indicators in the 10 languages indexed – and their stability – with the April 2012 version. The h-index and h-5 median of 1,000 journals were analysed, comparing their averages, maximum and minimum values and the correlation coefficient within rankings. The bibliometric fi...
In bibliometrics, interdsicsiplinatity is often measured in terms of the "diversity" of research areas in the references that an article cites. The standard indicators used are borrowed mostly from other research areas, notably from ecology (biodiversity measures) and economics (concentration measures). This paper discusses a new class of measures, which are used in the study of biodiversity an...
The British controversy over the validity of Urquhart’s and Garfield’s Laws during the 1970s constitutes an important episode in the formulation of the probability structure of human knowledge. This controversy took place within the historical context of the convergence of two scientific revolutions—the bibliometric and the biometric—that had been launched in Britain. The preceding decades had ...
This text is based on a translation of a chapter in a handbook about network analysis (published in German) where we tried to make beginners familiar with some basic notions and recent developments of network analysis applied to bibliometric issues (Havemann and Scharnhorst 2010). We have added some recent references.
Latent Semantic Analysis (LSA) has been in use in several different fields of science. Several modeling techniques including Boolean, settheoretic, vector space, and probabilistic models studied. In this paper, we first describe the concept of “LSA” and then present the preliminary results of an exploratory study. We carried out a small-scale bibliometric analysis to find out the impact of LSA ...
Percentiles have been established in bibliometrics as an important alternative to mean-based indicators for obtaining a normalized citation impact of publications. Percentiles have a number of advantages over standard bibliometric indicators used frequently: for example, their calculation is not based on the arithmetic mean which should not be used for skewed bibliometric data. This study descr...
This is a follow-up on the bibliometric evaluation of Finnish astronomy presented by the author at the LISA V conference in 2006. The data from the previous study are revisited to determine how a wider institutional base and mergers affect comparisons between research units. Bibliometrics can be an useful tool for evaluating research done in separate institutes working in the same field. The au...
