Abstract
Bibliographic information systems are the gateway to the wealth of informationheld and produced by libraries. However, despite their importance for discovering and exploring library resources, bibliographic information systems are still missing some of the core functions they should be providing to support users in their information seeking process and the tasks of finding, identifying, selecting, and navigating the resources. Our research looked at how we could better fulfil the missing objectives by proposing a model that could support a more efficient and user friendly presentation and navigation in user interfaces of bibliographic information systems. We have built our work on the concepts of work family, FRBR (Functional Requirements for Bibliographic Records) and information visualization, creating a model on how to bring together and present all versions of a work, related works, and other works by and about the author. The thesis describes all stages of model development and shows how the model was implemented into a FrbrVis prototype system. It further reports on two user studies, a formal experiment and an observational experiment that have been carried out to evaluate the usability of the proposed prototype system designs. Comparing four information visualization designs between themselves and comparing a FRBR-visual approach against a current bibliographic information system, the results showed that all FRBR-visual prototypes offered better user experience than the baseline system, but the hierarchical indented tree and sunburst design proved as the best, both in performance as well as user preference. The thesis also reports on usability issues discovered during the evaluation and gives pointers for future research.

Title:Vizualizacija rezultatov in podpora navigaciji v vmesnikih bibliografskih informacijskih sistemov
Abstract:
Bibliografski informacijski sistemi predstavljajo vrata do bogastva informacij, ki jih hranijo in kreirajo knjižnice. Vendar pa kljub njihovi pomembnosti za odkrivanje in raziskovanje knjižničnega gradiva, bibliografski informacijski sistemi še vedno ne premorejo vseh osnovnih funkcij, ki bi bile potrebne za dobro podporo uporabnikom pri njihovem iskanju in nalogah kot so najdenje, identifikacije, izbira, in navigacija med informacijskimi viri. V študiji smo raziskovali, kako bi lahko bolje izpolnili manjkajoče cilje in predlagali model, ki bi omogočil bolj učinkovito in uporabniku prijazno predstavitev in navigacijo v uporabniških vmesnikih bibliografskih informacijskih sistemov. Delo smo gradili na konceptih družine del, modela FZBZ (Funkcionalne zahteve za bibliografske zapise) in vizualizacije informacij ter tako ustvarili model, ki povezuje in skupaj prikazuje vse verzije in izdaje istega dela, povezana dela, in ostala dela istega avtorja ali dela o tem avtorju. Doktorska naloga opisuje vse stopnje izgradnje modela in prikazuje, kako je bil model implementiran v FrbrVis prototipni sistem. Poroča tudi o dveh uporabniških študijah, formalnem eksperimentu in opazovalnem eksperimentu, ki sta bila uporabljena za evalvacijo uporabnosti predlaganih prototipnih zasnov. Primerjava štirih različnih vizualizacijskih tehnik med seboj ter primerjava FZBZ-vizualnega pristopa s trenutno zasnovo bibliografskih informacijskih sistemov je pokazala, da so vse FZBZ-vizualne prototipne zasnove nudile boljšo uporabniško izkušnjo kot sistem, kakršen je danes v uporabi v večini knjižnic, pri čimer pa sta se najbolje tako v uporabnosti kot pri preferencah uporabnikov odrezala hierarhičen zamaknjen oris in krožni sosednostni prikaz. Naloga tudi poroča o težavah, ki so bile odkrite pri evalvaciji in poda smernice za nadaljnje raziskave.
