Cross-field comparison ofscientometric indicators 1 is severely hindered by the differences in publication and citation habits of science fields. However, relating publication and citation indicators to proper field-specific reference standards,relative indicators can be built, which may prove rather useful in the comparative assessment of scientists,(More)
A two-level hierarchic system of fields and subfields of the sciences, social sciences and arts and humanities is proposed. The system was specifically designed for scientometric (evaluation) purposes with the ultimate goal of classifying every single document into a well-defined category. This goal was achieved using a three-step iterative process. The(More)
An attempt is made to find statistical evidences of the relation between international co-authorship and citation impact. It was found that international co-authorship, in average, results inpublications with higher citation rates than purely domestic papers. No correlation has beenfound, however, between the strength of co-authorship links and the relative(More)
Scientific cooperation of the EU countries with other developed regions, with Economies in Transition and with Developing Countries is analysed as it is reflected in the bibliometric indicators of internationally co-authored publications. The citation attractivity of these publications shows that international scientific collaboration is particularly(More)
As a first element of a macro-level country-by-country cross-reference and cross-citation analysis, domestic/international character of reference and citation behavior of 36 countries is studied and compared with international co-authorship patterns. Indicators of reference and citation domesticity as well as reference-citation domesticity balance are(More)
The authors present ranked lists of world’s countries — with main focus on EU countries (together with newly acceeded and candidate countries) — by their h-index on various science fields. As main source of data Thomson Scientific’s Essential Science Indicators (ESI) database was used. EU countries have strong positions in each field but none of them can(More)
A common problem in comparative bibliometric studies at the meso and micro level is the differentiation and specialisation of research profiles of the objects of analysis at lower levels of aggregation. Already the institutional level requires the application of more sophisticated techniques than customary in evaluation of national research performance. In(More)
A number of advantages of nanostructured materials over bulk materials and their potential applications in many scientific and technological fields have been revealed in recent years. To find out the main growth and trends of this exciting new scienence and technology fields the growth rate of the nano-prefixed terms in the title of journal papers has been(More)
