"Die "Liste der fachlichen Nachschlagewerke zu den Normdateien" (NSW-Liste) stellt mit ihren derzeit rund 1.660 Einträgen ein verbindliches Arbeitsinstrument für die tägliche Praxis in der kooperativen Normdaten-pflege des deutschsprachigen Raumes, speziell für die Terminologiearbeit in der bibliothekarischen Sacherschließung dar. In jedem Normdatensatz der Schlagwortnormdatei (SWD) werden für den Nachweis und die Begründung der Ansetzungs- und Verweisungsformen eines Deskriptors im Feld "Quelle" Referenzwerke aus der so genannten Prioritätenliste (Rangfolge der Nachschlagewerke), darüber hinaus aus der gesamten NSW-Liste, festgehalten und normiert abgekürzt. In gedruckter Form erscheint diese von der Deutschen Nationalbibliothek (DNB) regelmäßig aktualisierte Liste jährlich mit einem Änderungsdienst (Änderungen, Neuauflagen; Neuaufnahmen) und steht seit einigen Jahren auch elektronisch abrufbar bereit. Dennoch ist sie "in die Jahre" gekommen. Eine verbesserte Form dieser Liste war ein langjähriges Desiderat für die Neuansetzungspraxis in der SWD. Erst eine Projektarbeit im Rahmen des ULG bot 2008/2009 in Wien die Gelegenheit, solch einem elektronischen Hilfsmittel entscheidend näher zu kommen. Das Projektergebnis war praxistauglich und wurde 2010 von der UB Wien in ein Content Management System (CMS) eingebettet. Zahlreiche Tests und funktionelle Anpassungen sowie eine genaue Durchsicht des Grunddatenbestandes und aller Links in den Katalog des Pilotverbundes (OBV) waren noch nötig, und auch die erste Aktualisierung nach der Druckausgabe 2010 führten wir durch, bevor wir im Herbst 2010 der Fachöffentlichkeit eine Beta-Version vorstellen konnten. Seither steht die Suche im NSW-Tool als Alternative zur Benützung der Druckausgabe allen frei zur Verfügung: http://www.univie.ac.at/nsw/. Sämtliche SWD-Kooperationspartner-Redaktionen und die Lokalen Redaktionen (ÖSWD-LRs) des Österreichischen Bibliothekenverbundes (OBV) können über das Web-Frontend von "NSW online" ihre Wünsche an die Redaktion der NSW-Liste (Fachabteilung SE, DNB) direkt im Tool deponieren (Korrekturanträge sowie Vorschläge zur Aufnahme fehlender oder neuer Nachschlagewerke) und frei im Internet zugängliche Volltexte zu den bereits in der Liste vorhandenen Titeln verlinken (Erstanmeldung über den Webmaster: via Hilfe-Seite im Tool).
Nur die Verbundbibliotheken des OBV können überdies ihre zu den Nachschlagewerken passenden Bestände in Aleph hinzufügen, ggf. selbst via Web-Frontend im Tool einen Link zum eigenen Verbundkatalog neu anlegen, und insbesondere ihre lokal verfügbaren elektronischen Volltexte anbinden3. Im Backend werden neue Datensätze angelegt, vorhandene Einträge korrigiert, redaktionelle Kommentare platziert und Korrekturanträge abgeschöpft sowie Neuauflagen für die richtige Anzeige und Verknüpfung, etwa mit der Rangfolgeliste, zu ihrem "Anker-Datensatz" umgelenkt. Außerdem werden hier HTML-Seiten wie Hilfetext, Rangfolgeliste u. ä. gepflegt. - Zum Administrationsinterface haben nur der Webmaster der UB Wien, die SWD-Zentralredaktion des OBV sowie die Fachabteilung SE der DNB Zugang. (Nicht nur) Sacherschließerinnen können das Tool mit all seinen Vorteilen nutzen und dennoch in gewohnter Weise vorgehen, wenn sie nach Quellen für ihre Neuansetzungen suchen wollen und darin recherchieren müssen, denn die Struktur des Tools folgt dem Aufbau der Druckfassung. Es empfiehlt sich, im jeweiligen Bibliothekssystem für SWD und PND zum Feld Quelle einen Hypertextlink im Erfassungsmodul anzubringen. Die Normdateiarbeit ist komplex und anspruchsvoll. Die Einhaltung der für alle Neuansetzungen verbindlichen Rangfolge wird mit dem Tool und seiner praxisorientierten Aufbereitung ganz entscheidend erleichtert, was von Beginn an zu einer hohen Qualität jedes Normdatensatzes verhilft. Den größten Zeitgewinn in der täglichen Praxis bringt der sofortige Zugriff auf verlinkte Volltexte. - Angesichts des zunehmenden multilateralen Datentausches bei gleichzeitiger dramatischer Verknappung personeller Ressourcen trotz eines erheblichen Anstiegs des inhaltlich zu erschließenden Literaturaufkommens wird dies im Workflow des vor kurzem eingeführten Online-Redaktionsverfahrens (ONR) für Normdateien der wohl nachhaltigste Effekt von "NSW online" sein."

Abstract

We illustrate the principle of unified treatment of all authority data for any kind of entities, subjects/topics, places, events, persons, organizations, etc. through the design and implementation of an enriched authority database for organizations, maintained as an integral part of an authority database that also includes subject authority control / classification data, using the same structures for data and common modules for processing and display of data. Organization-related data are stored in information systems of many companies. We specifically examine the case of the World Bank Group (WBG) according to organization role: suppliers, partners, customers, competitors, authors, publishers, or subjects of documents, loan recipients, suppliers for WBG-funded projects and subunits of the organization itself. A central organization authority where each organization is identified by a URI, represented by several names and linked to other organizations through hierarchical and other relationships serves to link data from these disparate information systems. Designing the conceptual structure of a unified authority database requires integrating SKOS, the W3C Organization Ontology and other schemes into one comprehensive ontology. To populate the authority database with organizations, we import data from external sources (e.g., DBpedia and Library of Congress authorities) and internal sources (e.g., the lists of organizations from multiple WBG information systems).

Abstract

Purpose - The purpose of this paper is to present functional requirements for bibliographic records (FRBR)-based model and functional requirements for authority data (FRAD)-based model; both of which incorporate an event concept that transforms FRBR and FRAD with minimal modification. Design/methodology/approach - Relationships between the entities defined in FRBR/FRAD are transformed into event entities and relationships with other kinds of entities. The cardinality of those relationships is also examined. In addition, a comparison of the proposed FRBR-based model with the object-oriented FRBR (FRBROO) is conducted. Findings - In the proposed event-aware FRBR model, an event and its output resource are dependent on each other and necessary information about an event can be expressed with information about its output resource, and vice versa. Therefore, the usefulness and expressiveness of the proposed model is limited. In the FRBROO model, dependency between an event and its output resource is not observed, except in a few cases, since a different resource and event modeling was adopted there. The event-aware FRAD model proposed is useful - but also the scope of its usefulness limited since dependency between an event and its input/output resource is not observed on some event entities. Originality/value - The proposed models are meaningful in terms of understanding the basic structure and features of a model that incorporates an event concept. The usefulness and limitation of event modeling have been clarified through such model building. The proposed models provide a stable basis for examining FRBR/FRAD further.

Abstract

Authority control is a standard practice in the library community that provides consistent, unique, and unambiguous reference to entities such as persons, places, concepts, etc. The ideal way of referring to authority records through unique identifiers is in line with the current linked data principle. When presenting a bibliographic record, the linked authority records are expanded with the authoritative information. This way, any update in the authority records will not affect the indexing of the bibliographic records. The structural information in the authority files can also be leveraged to expand the user's query to retrieve bibliographic records associated with all the variations, narrower terms or related terms. However, in many digital libraries, especially largescale aggregations such as WorldCat and Europeana, name strings are often used instead of authority record identifiers. This is also partly due to the lack of global authority records that are valid across countries and cultural heritage domains. But even when there are global authority systems, they are not applied at scale. For example, in WorldCat, only 15% of the records have DDC and 3% have UDC codes; less than 40% of the records have one or more topical terms catalogued in the 650 MARC field, many of which are too general (such as "sports" or "literature") to be useful for retrieving bibliographic records. Therefore, when a user query is based on a Dewey code, the results usually have high precision but the recall is much lower than it should be; and, a search on a general topical term returns millions of hits without being even complete. All these practices make it difficult to leverage the key benefits of authority files. This is also true for authority files that have been transformed into linked data and enriched with mapping information. There are practical reasons for using name strings instead of identifiers. One is the indexing and query response. The future infrastructure design should take the performance into account while embracing the benefit of linking instead of copying, without introducing extra complexity to users. Notwithstanding all the restrictions, we argue that largescale aggregations also bring new opportunities for better exploiting the benefits of authority records. It is possible to use machine learning techniques to automatically link bibliographic records to authority records based on the manual input of cataloguers. Text mining and visualization techniques can offer a contextual view of authority records, which in return can be used to retrieve missing or mis-catalogued records. In this talk, we will describe such opportunities in more detail.

Abstract

The paper introduces TinREAD (The Information Navigator for Readers), an integrated library system produced by IME Romania. The main feature of interest is the way TinREAD can handle a classification-based thesaurus in which verbal index terms are mapped to classification notations. It supports subject authority control interlinking the authority files (subject headings and UDC system). Authority files are used for indexing consistency. Although it is said that intellectual indexing is, unlike automated indexing, both subjective and inconsistent, TinREAD is using intellectual indexing as input (the UDC notations assigned to documents) for the automated indexing resulting from the implementation of a thesaurus structure based on UDC. Each UDC notation is represented by a UNIMARC subject heading record as authority data. One classification notation can be used to search simultaneously into more than one corresponding thesaurus. This way natural language terms are used in indexing and, at the same time, the link with the corresponding classification notation is kept. Additionally, the system can also manage multilingual data for the authority files. This, together with other characteristics of TinREAD are largely discussed and illustrated in the paper. Problems encountered and possible solutions to tackle them are shown.
