Improving the presentation of library data using FRBR and Linked data

When a library end-user searches the online catalogue for works by a particular author, he will typically get a long list that contains different translations and editions of all the books by that author, sorted by title or date of issue. As an attempt to make some order in this chaos, the Pode project has applied a method of automated FRBRizing based on the information contained in MARC records. The project has also experimented with RDF representation to demonstrate how an author’s complete production can be presented as a short and lucid list of unique works, which can easily be browsed by their different expressions and manifestations. Furthermore, by linking instances in the dataset to matching or corresponding instances in external sets, the presentation has been enriched with additional information about authors and works

Normalizing library records display using FRBR model for al-Qur'an work-set

The Functional Requirements for Bibliographic Records (FRBR) model is a conceptual entity-relationship model developed for better arrangement, collocation, and navigation in bibliographic databases. As such, a FRBRized library online catalog (OPAC) can improve the performance of OPAC as a retrieval tool. We explored the utility of FRBR framework for supporting rich indexation, and rich interaction in digital libraries using an open source FRBR tool developed by the Library of Congress. We tested the system on some MARC-based bibliographic records from the International Islamic University Malaysia (IIUM) library. Several issues have been found useful to be explored which includes multi-script, complex work, and missing fields. We also experimented on FRBRzing the work-set on al-Quran using the LOC FRBR Display Tool. This paper will elaborate on the process of FRBRizing using this open-source tool. Several problems encountered in the experiment are discussed and future enhancements are proposed. This work may initiate interest among the librarian to adopt FRBR as advancement to the existing digital library system

From MARC silos to Linked Data silos?

Libraries are opening up their bibliographic metadata as Linked Data. However, they have all used different data models for structuring their bibliographic data. Some are using a FRBR-based model with several layers of entities while others use flat, record-oriented data models. The proliferation of data models limits the reusability of bibliographic data. In effect, libraries have moved from MARC silos to Linked Data silos of incompatible data models. Data sets can be difficult to combine and reuse. Small modelling differences may be overcome by schema mappings, but it is not clear that interoperability has improved overall. We present a survey of published bibliographic Linked Data, the data models proposed for representing bibliographic data as RDF, and tools used for conversion from MARC. Also, the approach of the National Library of Finland is discussed. Seit einiger Zeit stellen Bibliotheken ihre bibliografischen Metadadaten verstärkt offen in Form von Linked Data zur Verfügung. Dabei kommen jedoch ganz unterschiedliche Modelle für die Strukturierung der bibliografischen Daten zur Anwendung. Manche Bibliotheken verwenden ein auf FRBR basierendes Modell mit mehreren Schichten von Entitäten, während andere flache, am Datensatz orientierte Modelle nutzen. Der Wildwuchs bei den Datenmodellen erschwert die Nachnutzung der bibliografischen Daten. Im Ergebnis haben die Bibliotheken die früheren MARC-Silos nur mit zueinander inkompatiblen Linked-Data-Silos vertauscht. Deshalb ist es häufig schwierig, Datensets miteinander zu kombinieren und nachzunutzen. Kleinere Unterschiede in der Datenmodellierung lassen sich zwar durch Schema Mappings in den Griff bekommen, doch erscheint es fraglich, ob die Interoperabilität insgesamt zugenommen hat. Der Beitrag stellt die Ergebnisse einer Studie zu verschiedenen veröffentlichten Sets von bibliografischen Daten vor. Dabei werden auch die unterschiedlichen Modelle betrachtet, um bibliografische Daten als RDF darzustellen, sowie Werkzeuge zur Erzeugung von entsprechenden Daten aus dem MARC-Format. Abschließend wird der von der Finnischen Nationalbibliothek verfolgte Ansatz behandelt

From the web of bibliographic data to the web of bibliographic meaning: structuring, interlinking and validating ontologies on the semantic web

Bibliographic data sets have revealed good levels of technical interoperability observing the principles and good practices of linked data. However, they have a low level of quality from the semantic point of view, due to many factors: lack of a common conceptual framework for a diversity of standards often used together, reduced number of links between the ontologies underlying data sets, proliferation of heterogeneous vocabularies, underuse of semantic mechanisms in data structures, "ontology hijacking" (Feeney et al., 2018), point-to-point mappings, as well as limitations of semantic web languages for the requirements of bibliographic data interoperability. After reviewing such issues, a research direction is proposed to overcome the misalignments found by means of a reference model and a superontology, using Shapes Constraint Language (SHACL) to solve current limitations of RDF languages.info:eu-repo/semantics/acceptedVersio

Next generation catalogues: an analysis of user search strategies and behavior

The movement from online catalogues to search and discovery systems has not addressed the goals of true resource discoverability. While catalogue user studies have focused on user search and discovery processes and experiences, and construction and manipulation of search queries, little insight is given to how searchers interact with search features of next generation catalogues. Better understanding of user experiences can help guide informed decisions when selecting and implementing new systems. In this study, fourteen graduate students completed a set of information seeking tasks using UIUC's VuFind installation. Observations of these interactions elicited insight into both search feature use and user understanding of the function of features. Participants used the basic search option for most searches. This is because users understand that basic search draws from a deep index that always gives results regardless of search terms; and because it is convenient, appearing at every level of the search, thus reducing effort and shortening search time. Participants rarely used advanced search but selected it as a secondary alternative, especially when searching for local library or print collections. Participants understand an online catalogue as a list of library holdings that provides access to local print collections; and offers options for refining voluminous result sets. Participants frequently used author, title, subject, keywords; and citation, search within, print, save, e-mailing, fulltext download that offered clear alternatives to searching and search reformulation respectively. Such features are familiar to users from past search experiences and puts them in control of the system. Participants understand the function of VuFind features based on their perception and preference that: VuFind will give relevant and current information because of the large collection size at UIUC; because of their prior experiences with quick, minimal effort search reformulation strategies; and VuFind‘s large result sets, presented in systematic and logical order. The evidence confirms that information tasks guide and shape the way searchers select and use system features. Participant search processes change during and after using a specific system. Alternatives to improve the design of more robust search features are proposed

Topic Maps and library and information science : an exploratory study of Topic Maps principles from a Knowledge and Information Organization perspective

Purpose: This master thesis attempts to present a ‘state of the art’ of the placement of Topic Maps (ISO13250) in Library and Information Science, through an extensive literature review and a synthesis based on their principles. It was sited from a Knowledge and Information Organization perspective, represented by the work by Elain Svenonius The Intellectual Foundation of Information Organization and some of the concepts of Knowledge Organization. This thesis also intends to present a conceptual and theoretical framework for future research. Design/methodology/approach: The study under review presents a qualitative approach based on Grounded Theory principles to analyse the literature and build the conceptual framework for its analysis. The literature reviewed consisted of more than sixty documents, which included, among others, journal articles, conference presentations and papers, student reports and thesis, as well as a book chapter. Moreover, this was complemented with information obtained from mailing lists, blog postings and websites, and some unstructured interviews. Findings: Topic Maps appears to be a development aligned within the tradition of Knowledge and Information Organization but is completely adapted to the context of the Web and the digital environments. In a LIS perspective, it is bibliographic meta-language able to represent, extend and mostly integrate all the existing Knowledge Organization Systems in a standards-based generic model applicable to digital content and online presentation. Conceptually, Topic Maps is in the borders of the LIS discipline with Knowledge Representation and Computer Science, where LIS conceptual models play the role of intermediaries by providing the ontologies to the ‘bibliographic universe’. Topic Maps questions traditional LIS views and principles. Even though some of them still remain the same, as the meaning-based identification of entities, the notions of ‘document’ and ‘subject’ require further studies. Some important applications give account of the capabilities and potentials for further developments and research on Topic Maps in LIS. The main field of application is the Digital Humanities and TEIcodified texts presentation.Joint Master Degree in Digital Library Learning (DILL

The “Black Box”: How Students Use a Single Search Box to Search for Music Materials

Given the inherent challenges music materials present to systems and searchers (formats, title forms and languages, and the presence of additional metadata such as work numbers and keys), it is reasonable that those searching for music develop distinctive search habits compared to patrons in other subject areas. This study uses transaction log analysis of the music and performing arts module of a library’s federated discovery tool to determine how patrons search for music materials. It also makes a top-level comparison of searches done using other broadly defined subject disciplines’ modules in the same discovery tool. It seeks to determine, to the extent possible, whether users in each group have different search behaviors in this search environment. The study also looks more closely at searches in the music module to identify other search characteristics such as type of search conducted, use of advanced search techniques, and any other patterns of search behavior.Ope
