Abstract

The MTSR 2013 program and the contents of these proceedings show a rich diversity of research and practices, drawing on problems from metadata and semantically focused tools and technologies, linked data, cross-language semantics, ontologies, metadata models, and semantic system and metadata standards. The general session of the conference included 18 papers covering a broad spectrum of topics, proving the interdisciplinary field of metadata, and was divided into three main themes: platforms for research data sets, system architecture and data management; metadata and ontology validation, evaluation, mapping and interoperability; and content management. Metadata as a research topic is maturing, and the conference also supported the following five tracks: Metadata and Semantics for Open Repositories, Research Information Systems and Data Infrastructures; Metadata and Semantics for Cultural Collections and Applications; Metadata and Semantics for Agriculture, Food and Environment; Big Data and Digital Libraries in Health, Science and Technology; and European and National Projects, and Project Networking. Each track had a rich selection of papers, giving broader diversity to MTSR, and enabling deeper exploration of significant topics.

Abstract

Purpose - The paper aims to argue that digital library retrieval should be based on semantic representations and propose a semantic infrastructure for digital libraries. Design/methodology/approach - The approach taken is formal model based on subject representation for digital libraries. Findings - Search engines and search techniques have fallen short of user expectations as they do not give context based retrieval. Deploying semantic web technologies would lead to efficient and more precise representation of digital library content and hence better retrieval. Though digital libraries often have metadata of information resources which can be accessed through OAI-PMH, much remains to be accomplished in making digital libraries semantic web compliant. This paper presents a semantic infrastructure for digital libraries, that will go a long way in providing them and web based information services with products highly customised to users needs. Research limitations/implications - Here only a model for semantic infrastructure is proposed. This model is proposed after studying current user-centric, top-down models adopted in digital library service architectures. Originality/value - This paper gives a generic model for building semantic infrastructure for digital libraries. Faceted ontologies for digital libraries is just one approach. But the same may be adopted by groups working with different approaches in building ontologies to realise efficient retrieval in digital libraries.

Zusammenarbeit mit Bibliotheken Bereits früh setzte sich Tim Spalding für eine Zusammenarbeit mit Bibliotheken ein. Zum Eintragen von neuen Büchern in LibraryThing können zahlreiche Bibliothekskataloge ausgewählt werden, die via Z39.50 eingebunden werden - seit Oktober 2006 ist auch der GBV dabei. Im April 2007 veröffentlichte Tim Spalding mit LibraryThing for Libraries ein Reihe von Webservices, die Bibliotheken in ihre OPACs einbinden können.4 Ein Webservice ist eine Funktion, die von anderen Programmen über das Web aufgerufen werden kann und Daten zurückliefert. Bereits seit Juni 2006 können über verschiedene offene LibraryThing-Webservices unter Anderem zu einer gegebenen ISBN die Sprache und eine Liste von ISBNs anderer Auflagen und Übersetzungen ermittelt werden, die zum gleichen Werk gehören (thinglSBN). Damit setzt LibraryThing praktisch einen Teil der Functional Requirements for Bibliographic Records (FRBR) um, die in bibliothekswissenschaftlichen Fachkreisen bereits seit Anfang der 1990er diskutiert werden, aber bislang nicht so Recht ihre Umsetzung in Katalogen gefunden haben. Die Information darüber, welche Bücher zum gleichen Werk gehören, wird von der LibraryThing-Community bereitgestellt; jeder Benutzer kann einzelne Ausgaben mit einem Klick zusammenführen oder wieder trennen. Vergleiche mit dem ähnlichen Dienst xISBN von OCLC zeigen, dass sich thinglSBN und xISBN gut ergänzen, allerdings bietet LibraryThing seinen Webservice im Gegensatz zu OCLC kostenlos an. Neben Empfehlungen von verwandten Büchern ist es im Rahmen von LibraryThing for Libraries auch möglich, die von den Nutzern vergebenen Tags in den eigenen Katalog einzubinden. Ein Nachteil dabei ist allerdings die bisherige Übermacht der englischen Sprache und dass nur selbständige Titel mit ISBN berücksichtigt werden. Die VZG prüft derzeit, in welcher Form LibraryThing for Libraries am besten in GBV-Bibliotheken umgesetzt werden kann. Es spricht allerdings für jede einzelne Bibliothek nichts dagegen, schon jetzt damit zu experimentieren, wie der eigene OPAC mit zusätzlichen Links und Tags von LibraryThing aussehen könnte. Darüber hinaus können sich auch Bibliotheken mit einem eigenen Zugang als Nutzer in LibraryThing beteiligen. So stellt beispielsweise die Stadtbücherei Nordenham bereits seit Ende 2005 ihre Neuzugänge im Erwachsenenbestand in einer Sammlung bei LibraryThing ein.
Beispiel für die Anwendung von LibraryThing for Libraries im Katalog des Waterford Institute of Technology (): Zu einer ISBN werden auf Basis der in LibraryThing gesammelten Daten andere Auflagen und Übersetzungen, ähnliche Bücher und Tags eingeblendet. Soziale Software lebt vom Mitmachen Vieles spricht dafür, dass LibraryThing auf dem besten Weg ist, sich zu einem der wichtigsten Web 2.0-Dienste für die Zusammenarbeit mit Bibliotheken zu entwickeln. Wie schon bei Wikipedia gibt es allerdings noch viel zu oft Berührungsängste und die Vorstellung, dass sich diese Dienste erst durch Hilfe von Außen in der eigenen Einrichtung einführen ließen. Soziale Software lebt jedoch von der Zusammenarbeit und dem freien Austausch von Gedanken und Informationen. Deshalb hilft nur eins: Ausprobieren und Mitmachen. Ebenso wie Wikipedia schwer zu beurteilen ist, ohne selbst mit anderen Wikipedianern einen Artikel erstellt und diskutiert zu haben, erschließt sich LibraryThing erst vollständig durch eine eigene dort angelegte Büchersammlung. Zum Kennenlernen reicht der kostenlose Zugang und mit 15 $ Jahresgebühr können auch Bibliotheken problemlos bis zu 5.000 Medieneinheiten pro Sammlung einstellen. Wenn Sie erstmal mehr mit Library-Thing vertraut sind, werden Ihnen sicherlich weitere Einsatzmöglichkeiten für Ihre Einrichtung und deren Nutzer einfallen. LibraryThing entwickelt sich beständig weiter und dürfte noch für einige Überraschungen gut sein.

Abstract

This exploratory study examined Linked Data (LD) schemas/ontologies and data models proposed or in use by libraries around the world using MAchine Readable Cataloging (MARC) as a basis for comparison of the scope and extensibility of these potential new standards. The researchers selected 14 libraries from national libraries, academic libraries, government libraries, public libraries, multi-national libraries, and cultural heritage centers currently developing Library Linked Data (LLD) schemas. The choices of models, schemas, and elements used in each library's LD can create interoperability issues for LD services because of substantial differences between schemas and data models evolving via local decisions. The researchers observed that a wide variety of vocabularies and ontologies were used for LLD including common web schemas such as Dublin Core (DC)/DCTerms, Schema.org and Resource Description Framework (RDF), as well as deprecated schemas such as MarcOnt and rdagroup1elements. A sharp divide existed as well between LLD schemas using variations of the Functional Requirements for Bibliographic Records (FRBR) data model and those with different data models or even with no listed data model. Libraries worldwide are not using the same elements or even the same ontologies, schemas and data models to describe the same materials using the same general concepts.

Abstract

Purpose - The general science portal "vascoda" merges structured, high-quality information collections from more than 40 providers on the basis of search engine technology (FAST) and a concept which treats semantic heterogeneity between different controlled vocabularies. First experiences with the portal show some weaknesses of this approach which come out in most metadata-driven Digital Libraries (DLs) or subject specific portals. The purpose of the paper is to propose models to reduce the semantic complexity in heterogeneous DLs. The aim is to introduce value-added services (treatment of term vagueness and document re-ranking) that gain a certain quality in DLs if they are combined with heterogeneity components established in the project "Competence Center Modeling and Treatment of Semantic Heterogeneity". Design/methodology/approach - Two methods, which are derived from scientometrics and network analysis, will be implemented with the objective to re-rank result sets by the following structural properties: the ranking of the results by core journals (so-called Bradfordizing) and ranking by centrality of authors in co-authorship networks. Findings - The methods, which will be implemented, focus on the query and on the result side of a search and are designed to positively influence each other. Conceptually, they will improve the search quality and guarantee that the most relevant documents in result sets will be ranked higher. Originality/value - The central impact of the paper focuses on the integration of three structural value-adding methods, which aim at reducing the semantic complexity represented in distributed DLs at several stages in the information retrieval process: query construction, search and ranking and re-ranking.
