A Machine for Automatic Subject Indexing Using ToC
Pokorný, Jan
The technology developed in the National Library of Technology can extract a document’s table of content (TOC), generate relevant keywords, and suggest terms for various classification schemas (UDC, DDC, LCC, Conspectus). It can fully or substantially automate the process of generating subject access, unite it across libraries, and significantly increase accuracy and relevancy compared to subject assignments by non-specialist catalogers. Such increased quality in subject access terms is often seen in the superior subject facets generated by discovery systems and library OPAC advanced search forms.

International conference ELPUB 2015
Pokorný, Jan
Cílem účasti na mezinárodní konferenci ELPUB byla konfrontace znalostí a postupů v oblasti zpřístupňování digitálního obsahu. Letošní ročník byl dvěma nosným tématům, které jsou pro NTK aktuální: problematika vyhledávání a zpřístupňování obsahu vzhledem k vzrůstajícímu množství informací spolu s fyzickým objemem sbírek a problematika indexování netextových dokumentů.

Unification of Subject Description of Aggregated Records in National Repository of Grey Literature
Charvátová, Michaela ; Bratková, Eva (advisor) ; Kučerová, Helena (referee)
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. Powered by TCPDF (www.tcpdf.org)

Online Subject Searching of Dissertations
Bratková, Eva
This paper evaluates searching for doctoral dissertations by topic in various online systems. The situation in the Czech Republic is introduced, including the problems involved in completing successful topical searches for dissertations – is it possible to find all relevant materials, or is it sufficient just to find something? The Czech situation is then compared with how systems abroad, particularly in the United States, are being implemented with new access routes for dissertations in the form of linked open data, in which controlled vocabularies of subject terms figure prominently. The paper also discusses how selected European systems whose dissertations are already presented in the WorldCat database will cope with a challenge: “... Over time, these references [for topic entities] will be replaced with persistent URIs to... Linked Data resources”?
