Vpliv odprtega dostopa na citiranost znanstvenih objav s področja gradbeništva

Teja Koler Povh

Izvleček


Razvoj znanosti spremlja tudi rast znanstvenih objav, predvsem v obliki člankov v recenziranih znanstvenih revijah. Analizirali smo znanstvene članke iz 14 mednarodnih znanstvenih revij z dejavnikom vpliva s področja gradbeništva, vključene v JCR vsebinsko kategorijo Civil engineering, objavljenih leta 2007. Članke smo razvrstili v dve skupini, odprto dostopne članke (članki OA) in članke, ki niso odprto dostopni (članki NONOA). Ugotavljali smo vpliv odprtega dostopa na število citatov v obdobju od objave leta 2007 do konca leta 2012. Na osnovi vrednosti dejavnika vpliva in razvrstitve v kvartile smo proučevali tudi vpliv kakovosti revije na število citatov, ločeno za članke OA in NONOA. Citiranost smo proučevali po podatkovnih zbirkah WoS, Scopus in Google Scholar (GS) ter podatke primerjali. Prvi dve zbirki sta v Sloveniji dostopni le univerzam in raziskovalnim ustanovam ob plačilu licenčnin, v nasprotju z zbirko GS.

Za proučevanih 2026 člankov smo ugotovili, da je 21 % objavljenih kot članki OA in dosegajo 29 % vseh citatov v proučevanem obdobju od objave leta 2007 do konca 2012. Največ citatov je odkritih v zbirki GS. V zbirki GS dosegajo v povprečju članki OA več citatov kot članki NONOA v revijah prvih treh kvartilov, v zbirkah WoS in Scopus pa lahko z dovoljeno stopnjo tveganja α = 5 % trdimo le za članke, objavljene v revijah 1. kvartila, da dosegajo članki OA več citatov kot članki NONOA. Mestoma se ta rezultat izkaže tudi pri posameznih revijah 2. kvartila. Zaključimo lahko, da za znanstvene članke s področij gradbeništva, objavljene v kakovostnih revijah, velja, da so odprto dostopni članki citirani večkrat kot odprto nedostopni.

Ključne besede: znanstvene objave, gradbeništvo, citiranost, odprti dostop, vpliv na citiranost
