datos.bne.es: A library linked dataset
Social Work, 2013Co-Authors: Daniel Vila-suero, Boris Villazón-terrazas, Asunción Gómez-pérezAbstract:We describe the datos.bne.es library dataset. The dataset makes available the Authority and bibliography catalogue from the Biblioteca Nacional de Espaoa BNE, National Library of Spain as Linked Data. The catalogue contains around 7 million Authority and bibliographic records. The records in MARC 21 format were transformed to RDF and modelled using IFLA International Federation of Library Associations ontologies and other well-established vocabularies such as RDA Resource Description and Access or the Dublin Core Metadata Element Set. A tool named MARiMbA automatized the RDF generation process and the data linkage to DBpedia and other library linked data resources such as VIAF Virtual International Authority File or GND Gemeinsame Normdatei, the Authority dataset from the German National Library.

Einbindung von RVK-Registerbegriffen in die Katalogrecherche – eine Analyse des Potenzials und der Umsetzungsmöglichkeiten am Beispiel des K10plus
2020Co-Authors: Hasubick JuliaAbstract:The Regensburger Verbundklassifikation (RVK) is an established classification scheme for academic libraries and includes index terms for finding classification marks of the RVK. The RVK index terms have been linked to the Integrated Authority File (GND) since 2016. As a result, new opportunities to use the index terms for library catalogue searches have opened up – especially within the context of “explorative searches” as an application possibility for further searches. As these opportunities are barely used yet, the present thesis examines if and to what extent index terms of the RVK are qualified for an integration into library catalogue search. In doing so the following aspects are addressed: To what extent can the index terms of the RVK be utilized for further catalogue searches? Are there parts of the RVK, certain types or the like, which are not or especially qualified for an integration? How to deal with classification marks with more than one index term? The results of the present thesis are based on a quantitative and qualitative evaluation of classification mark samples from selected sections of the RVK. Therefore, title data records, that hold index terms of classification marks as subject headings, are retrieved by use of search requests in the WinIBW. Besides an analysis of the hit rate, the quality of the achieved results is evaluated based on a specially developed scale. The scale shows the extent to which a retrieved title data record corresponds or fits to a classification mark of the RVK (“level of correspondency”). The examined classification marks and their index terms are pooled in three general categories: definitely qualified, definitely not qualified and a major part of cases, that can reasonably only be integrated in catalogue searches under wide preliminary work

Einbindung von RVK-Registerbegriffen in die Katalogrecherche - eine Analyse des Potenzials und der Umsetzungsmöglichkeiten am Beispiel des K10plus
2020Co-Authors: Hasubick JuliaAbstract:Die Regensburger Verbundklassifikation (RVK) ist ein etabliertes Klassifikationssystem für wissenschaftliche Bibliotheken und beinhaltet zur Recherche von Notationen Registerbe-griffe. Mit der seit 2016 umgesetzten Verknüpfung der RVK-Registerbegriffe mit der Ge-meinsamen Normdatei (GND) eröffnen sich Möglichkeiten diese für die Katalogrecherche – insbesondere im Rahmen der „entdeckenden Suche“ als Möglichkeit für Anschluss-recherchen – einzusetzen. Da diese Möglichkeiten bislang kaum genutzt werden, wird im Rahmen der vorliegenden Arbeit untersucht, ob und inwiefern sich die RVK-Registerbegriffe für eine Einbindung in die Katalogrecherche eignen. Dabei wird auf fol-gende Fragen eingegangen: Inwieweit können die Registerbegriffe für Anschlussrecher-chen verwendet werden? Gibt es RVK-Bereiche, bestimmte Typen oder ähnliches, die sich nicht oder besonders gut eigenen? Wie ist mit Notationen umzugehen, welche mehrere Registereinträge aufweisen? Die Ergebnisse der vorliegenden Arbeit basieren auf einer quantitativen und qualitativen Auswertung von Notationsstichproben aus ausgewählten RVK-Systematiken. Hierfür werden mittels Suchanfragen in der WinIBW Titeldaten aus dem K10plus-Katalog abgefragt, welche die Registereinträge einer Notation als Schlagwör-ter besitzen. Neben einer Analyse der Treffermengen wird anhand eine eigens entwickelte Skala die Qualität der erzielten Titeltreffer bewertet. Die Skala gibt an, in welchem Maße ein gefundener Titel zu einer RVK-Systemstelle passt („level of correspondency“). Die un-tersuchten Notationen und deren Registereinträge können im Wesentlichen zu drei Kate-gorien zusammengefasst werden: eindeutig geeignete, eindeutig nicht geeignete und ein Großteil an Fällen, die nur unter umfassenden Vorarbeiten sinnvoll in die Katalogrecher-che eingebunden werden können.The Regensburger Verbundklassifikation (RVK) is an established classification scheme for academic libraries and includes index terms for finding classification marks of the RVK.

a framework for unified Authority Files a case study of corporate body names in the fao catalogue
International Conference Theory and Practice Digital Libraries, 2003Co-Authors: James Weinheimer, Kafkas CaprazliAbstract:We present a Unified Authority File for Names for use with the FAO Catalogue. This Authority File will include all authorized forms of names, and can be used for highly precise resource discovery, as well as for record sharing. Other approaches of creating unified Authority Files are discussed. A major advantage of our proposal lies in the ease and sustainability of sharing records across Authority Files. The public would benefit from the Unified Authority File with its possibilities for cross-collection searching, and metadata creators would also have a greater possibility to utilize bibliographic records from other collections. A case study describes the treatment and use of corporate body names used in the catalogue of The Food and Agriculture Organization of the United Nations.

PVAF: an environment for disambiguation of scientific publication venues
International Journal on Digital Libraries, 2020Co-Authors: Tiago Antônio Paraizo, Denilson Alves PereiraAbstract:A publication venue Authority File stores variants of the names of journals and conferences that publish scientific articles. It is useful in the construction of search tools and data disambiguation, and it is of special interest to agencies funding research and evaluating graduate programs, which use the quality of publication venues as a basis for evaluating researchers’ and research groups’ publications. However, keeping an updated Authority File is not a trivial task. Different names are used to refer to the same publication venue, these venues sometimes change their name, new venues emerge regularly, and journal bibliometrics are updated frequently. This paper presents the publication venue Authority File (PVAF), an environment for the disambiguation of scientific publication venues. It consists of an Authority File and a set of tools for updating and querying its data. We describe and experimentally evaluate each of these tools. We also propose a search algorithm based on an associative classifier, which allows for incremental updates of its learning model. The results show that the PVAF has coverage greater than 86% for publication venues in several fields of knowledge, and its tools attain a good accuracy in the classification of publication venues from curricula vitae formatted in various citation styles.

enriching an Authority File of scientific conferences with information extracted from the web
Journal of Computer Science, 2017Co-Authors: Heider Alvarenga De Jesus, Denilson Alves PereiraAbstract:Authority Files maintain variant forms to refer to the same entity and they are very useful in digital libraries. However, collect data and keep an updated Authority File is not a trivial task. This paper proposes an approach for the enrichment of a publication venue Authority File by extracting information on conferences from their web pages. Collecting additional data is important to improve the effectiveness of data disambiguation tools and information retrieval, such as those that measure the quality of a scientific publication based on bibliometrics (e.g., Journal Impact Factor). Most applications use only basic citation metadata, such as author's names, work and publication venue titles. However, data external to the publication, contained in the publication venue web page, can be very useful in the disambiguation task. Our approach includes the steps for querying a web search engine, classifying documents obtained in the result sets and extracting information from the relevant pages. We evaluated two methods for classifying documents, one based on genre and content and one based on content only. The experiments show good results to trace a history of conference editions, with data such as URL, year of each edition and dates of changing in their names.
