Sjednocovánà věcného popisu agregovaných záznamů v repozitáři NUŠL: Unification of Subject Description of Aggregated Records in National Repository of Grey Literature
Diplomová práce se zabĂ˝vá metodami sjednocenĂ vÄ›cnĂ©ho popisu v záznamech agregovanĂ˝ch z rĹŻznĂ˝ch zdrojĹŻ v prostĹ™edĂ digitálnĂho repozitáře na pĹ™Ăkladu NárodnĂho ĂşloĹľištÄ› šedĂ© literatury (NUĹ L). Po pĹ™edstavenĂ zahraniÄŤnĂch zkušenostĂ ze systĂ©mĹŻ BASE a LASSO je popsána i souÄŤasná praxe v repozitáři NUĹ L, v nÄ›mĹľ je k jednotnĂ©mu popisu pomocĂ PolytematickĂ©ho strukturovanĂ©ho hesláře (PSH) vyuĹľĂvána automatická indexace. V rámci práce byly na PSH namapovány skupiny Konspektu a tezaurus MeSH. Tato mapovánĂ byla aplikována na záznamy pĹ™ebĂranĂ© do systĂ©mu NUĹ L z NárodnĂ lĂ©kaĹ™skĂ© knihovny a v prĹŻbÄ›hu navrĹľenĂ©ho experimentu byl srovnán vĂ˝slednĂ˝ vÄ›cnĂ˝ popis tvoĹ™enĂ˝ hesly PSH pĹ™iĹ™azenĂ˝ch na základÄ› vytvoĹ™enĂ˝ch mapovánĂ a vÄ›cnĂ˝ popis vytvoĹ™enĂ˝ automatickou indexacĂ. KromÄ› toho byla Ĺ™ešena i moĹľnost mapovánĂ autorskĂ˝ch klĂÄŤovĂ˝ch slov popisujĂcĂch vysokoškolskĂ© kvalifikaÄŤnĂ práce v záznamech pocházejĂcĂch z repozitářů spolupracujĂcĂch vysokĂ˝ch škol.The diploma thesis focuses on subject description unification methods in records aggregated from different sources in digital repositories, using the example of the National Repository of Grey Literature (NRGL). After presenting experiences with systems BASE and LASSO abroad, I describe the current situation in NRGL, where the automatic indexing is used to assign each record a unified subject heading from the Polythematic Structured Subject Heading System (PSSHS). The thesis then presents how the MeSH thesaurus and Conspectus categorization scheme were mapped to PSSHS. These mappings were then applied to records from the National Medical Library. The aim of the experiment was to compare the subject description consisting of PSSHS subject headings created by automatic indexing, and the subject description created by mapping. In addition to that I explore the possibilities of mapping author keywords in records of academic theses
