| KRATKA VSEBINA | Despite some criticism and the search for alternative methods of citation analysis it's an important bibliometric method, which measures the impact of published research results. In the last decade, special attention has been paid to highly cited papers, publications representing the highest quality, scientific excellence. In two studies, we have studied the highly cited papers in Slovenian co-authorship published in journals indexed in the bibliographic databases Web of Science and Scopus. These are defined as papers ranking by the number of citations among the top per cent in a given research field. The first hypothesis was that highly cited publications co-authored by Slovenian researchers are published in the top quarter ranked journals in agiven field of research, and the second that these papers are written in international collaboration and that Slovenian authors are a minority amongthe authors. The hypothesis that Slovenian authors form a minority in international co-authored teams was confirmed only in the case of the top one per cent most cited publications, but not in the case of publications in the top ten per cent most cited publications. The use of indicators related to most prestigious journals for the evaluation purposes is particularly well suited when growth in the number of publications is high,but the impact is not corresponding, as is the case in Slovenia. // Kljub nekaterim kritikam in iskanju alternativnih metod, je analiza citiranja pomembna bibliometrijska metoda, s katero merimo odzivnost objavljenih raziskovalnih rezultatov. V zadnjem desetletju se posebna pozornost namenjavisokocitiranim objavam, ki predstavljajo najvišjo kakovost, znanstveno odličnost. V dveh študijah smo obravnavali visoko citirane objave v slovenskem soavtorstvu v revijah, indeksiranih v bibliografskih bazah Web of Science in Scopus. Gre za objave, ki se po številu citatov uvrščajo v zgornji odstotek oziroma zgornjih 10 odstotkov objav na določenem raziskovalnem področju. V zvezi z visoko citiranimi objavami v slovenskem soavtorstvu smo postavili dve hipotezi. Prva, da so visoko citirane objave v slovenskem soavtorstvu objavljene v visoko rangiranih revijah, in druga, da so visoko citirane objave v slovenskem soavtorstvu nastale praviloma v sodelovanju s kolegi iz tujine in da slovenski soavtorji v teh soavtorskih timih tvorijo manjšino. Hipotezo, da so slovenski soavtorji praviloma v manjšini v mednarodnih soavtorskih timih, smo potrdili v primeru objav iz zgornjega odstotka najbolj citiranih objav, ne pa tudi v primeru objav iz zgornjih 10 odstotkov najbolj citiranih objav. Večja uporaba kazalnikov, vezanih na visoko citirane objave, se v postopkih merjenja raziskovalnih rezultatov zdi še posebej primerna v okoljih, kot je slovensko, kjer je visoka rast števila objav, ki ji ne sledi ustrezna odmevnost. |
