Pregled sistemov predmetnih oznak za področje znanosti o živalih v izbranih biotehniških podatkovnih zbirkah = Overview of systems of subject headings in the field of animal sciences, production and protection in selected agricultural databasesBartol, Tomaž, BFČlanek obravnava tri najpomebnejše biotehniške/kmetijske podatkovne zbirke Agricola, Agris, in CAB Abstracts (CABA) glede na predmetne oznake o znanosti o živalih (proizvodnja in varstvo živali, ... veterina). Podan je obsežen pregled zbirk, indeksiranje in klasifikacijske sheme. Predstavljeni so koncepti, kot so ontologije in metapodatki. Prikazane so predmetne kategorije in razlike med zbirkami pri opisovanju vsebin o živalih, akvakulturi in ribištvu. Različni pojmi se uporabljajo za podobne koncepte. Drevesaste strukture, tezavri, ključne besede oz. deskriptorji so predstavljeni glede na ožje in širše pojme, preferenčne pojme, nedeskriptorje in sorodne pojme oz. gesla. Obstajajo različne hierarhične smeri glede na proizvodne ali taksonomske koncepte. CABA ima najbolj kompleksno hierarhično drevo v smislu taksonomije. V različnih zbirkah se uporabljajo različne relacije med deskriptorji, nedeskriptorji in sorodnimi gesli, zato je kartiranje vsebine odvisno od podatkovne zbirke. Zaslonske slike opisujejo rabo spletnih tezavrov. Prikazane so večjezikovne funkcije tezavra Agrovoc. Portali oz. platforme so obravnavane glede na iskalno sintakso, fraze, boolovo logiko, znake za krajšanje ali maskiranje. Razlike med zbirkami vplivajo na natančnost in odziv oz. priklic ter šum. Za učinkovitejšo rabo bi morali uporabniki pridobiti več znanj o učinkovitih rabah podatkovnih zbirk in informacijskih sistemov.Source: Acta agriculturae Slovenica. - ISSN 1581-9175 (Letn. 94, št. 1, okt. 2009, str. 55-69)Type of material - article, component partPublish date - 2009Language - slovenianCOBISS.SI-ID - 2540424
