    Abstract
    This paper reports on the second part of an initiative of the authors on researching classification systems with the conceptual model defined by the Functional Requirements for Subject Authority Data (FRSAD) final report. In an earlier study, the authors explored whether the FRSAD conceptual model could be extended beyond subject authority data to model classification data. The focus of the current study is to determine if classification data modeled using FRSAD can be used to solve real-world discovery problems in multicultural and multilingual contexts. The paper discusses the relationships between entities (same type or different types) in the context of classification systems that involve multiple translations and /or multicultural implementations. Results of two case studies are presented in detail: (a) two instances of the DDC (DDC 22 in English, and the Swedish-English mixed translation of DDC 22), and (b) Chinese Library Classification. The use cases of conceptual models in practice are also discussed.

    Abstract
    Aufgrund der durch die Nutzer verstärkt geforderten Zusammenführung bislang verteilt vorliegender Informationssammlungen an einer Stelle tritt in der Praxis ein Phänomen zu Tage, das mit Blick auf die einzelne Informationssammlung in vielen Fällen bereits als gelöst betrachtet wurde: Heterogenität. Es zeigt sich, dass Standardisierungsansätze oft zu kurz greifen, da sie für die praktische Anwendung keine Modelle bieten, die trotz Standardisierungsbemühungen verbleibenden Unterschiede effizient und wirksam zu behandeln. Der Artikel stellt anhand zweier Beispiele aus dem Bereich der Fachinformation Lösungswege vor, wie in der Praxis Heterogenität zwischen Informationssammlungen auf semantischer Ebene behandelt werden kann. Sie tritt immer dann auf, wenn mehrere Quellen gleichzeitig durchsucht werden sollen, diese aber mit unterschiedlichen Indexierungsvokabularen erschlossen wurden. Am Beispiel statistischer Daten für die Marktforschung und wissenschaftlicher Literaturinformationssysteme werden Lösungen vorgestellt, mit dem Erschließungsvokabulare so aufeinander abgebildet werden können, dass sie Nutzer sowohl bei der Anfrageformulierung unterstützen können als auch bei der Suche eine für den Nutzer transparente und automatische Anfragetransformation ermöglichen. Ziel dieser Verfahren ist es, die kognitive Last beim Nutzer währender der Anfrageformulierung zu verringern und den Recall von Suchen in heterogen erschlossenen Informationssammlungen zu erhöhen.

    Abstract
    A case study in compatibility and heterogeneity of knowledge organization (KO) systems and processes is presented. It is based in the experience of the author in the field of information for consumer protection, a good example of the emerging transdisciplinary applied social sciences. The activities and knowledge organization problems and solutions of the Aragonian Consumers' Information and Documentation Centre are described and analyzed. Six assertions can be concluded: a) heterogeneity and compatibility are certainly an inherent problem in knowledge organization and also in practical domains; b) knowledge organization is also a social task, not only a lögical one; c) knowledge organization is affected by economical and efficiency considerations; d) knowledge organization is at the heart of Knowledge Management; e) identifying and maintaining the focus in interdisciplinary fields is a must; f the different knowledge organization tools of a institution must be considered as an integrated system, pursuing a unifying model.

    Abstract
    As a part of a research project aiming to connect library data to the unfamiliar data sets available in the Linked Data (LD) community's CKAN Data Hub (thedatahub.org), this project collected, analyzed, and mapped properties used in describing and accessing music recordings, scores, and music-related information used by selected music LD data sets, library catalogs, and various digital collections created by libraries and other cultural institutions. This article reviews current efforts to connect music data through the Semantic Web, with an emphasis on the Music Ontology (MO) and ontology alignment approaches; it also presents a framework for understanding the life cycle of a musical work, focusing on the central activities of composition, performance, and use. The project studied metadata structures and properties of 11 music-related LD data sets and mapped them to the descriptions commonly used in the library cataloging records for sound recordings and musical scores (including MARC records and their extended schema.org markup), and records from 20 collections of digitized music recordings and scores (featuring a variety of metadata structures). The analysis resulted in a set of crosswalks and a unified crosswalk that aligns these properties. The paper reports on detailed methodologies used and discusses research findings and issues. Topics of particular concern include (a) the challenges of mapping between the overgeneralized descriptions found in library data and the specialized, music-oriented properties present in the LD data sets; (b) the hidden information and access points in library data; and (c) the potential benefits of enriching library data through the mapping of properties found in library catalogs to similar properties used by LD data sets.

    Abstract
    Named Entities (benannte Entitäten) - wie Personen, Organisationen, Orte, Ereignisse und Werke - sind wichtige inhaltstragende Komponenten eines Dokuments und sind daher maßgeblich für eine gute inhaltliche Erschließung. Die Erkennung von Named Entities, deren Auszeichnung (Annotation) und Verfügbarmachung für die Suche sind wichtige Instrumente, um Anwendungen wie z. B. die inhaltliche oder semantische Suche in Texten, dokumentübergreifende Kontextualisierung oder das automatische Textzusammenfassen zu verbessern. Inhaltlich präzise und nachhaltig erschlossen werden die erkannten Named Entities eines Dokuments allerdings erst, wenn sie mit einer oder mehreren Quellen verknüpft werden (Grundprinzip von Linked Data, Berners-Lee 2006), die die Entität eindeutig identifizieren und gegenüber gleichlautenden Entitäten disambiguieren (vergleiche z. B. Berlin als Hauptstadt Deutschlands mit dem Komponisten Irving Berlin). Dazu wird die im Dokument erkannte Entität mit dem Entitätseintrag einer Normdatei oder einer anderen zuvor festgelegten Wissensbasis (z. B. Gazetteer für geografische Entitäten) verknüpft, gewöhnlich über den persistenten Identifikator der jeweiligen Wissensbasis oder Normdatei. Durch die Verknüpfung mit einer Normdatei erfolgt nicht nur die Disambiguierung und Identifikation der Entität, sondern es wird dadurch auch Interoperabilität zu anderen Systemen hergestellt, in denen die gleiche Normdatei benutzt wird, z. B. die Suche nach der Hauptstadt Berlin in verschiedenen Datenbanken bzw. Portalen. Die Entitätenverknüpfung (Named Entity Linking, NEL) hat zudem den Vorteil, dass die Normdateien oftmals Relationen zwischen Entitäten enthalten, sodass Dokumente, in denen Named Entities erkannt wurden, zusätzlich auch im Kontext einer größeren Netzwerkstruktur von Entitäten verortet und suchbar gemacht werden können

    Abstract
    Normdaten spielen speziell im Hinblick auf die Qualität der Inhaltserschließung bibliografischer und archivalischer Ressourcen eine wichtige Rolle. Ein konkretes Ziel der Inhaltserschließung ist z. B., dass alle Werke über Hermann Hesse einheitlich zu finden sind. Hier bieten Normdaten eine Lösung, indem z. B. bei der Erschließung einheitlich die GND-Nummer 11855042X für Hermann Hesse verwendet wird. Das Ergebnis ist eine höhere Qualität der Inhaltserschließung vor allem im Sinne von Einheitlichkeit und Eindeutigkeit und, daraus resultierend, eine bessere Auffindbarkeit. Werden solche Entitäten miteinander verknüpft, z. B. Hermann Hesse mit einem seiner Werke, entsteht ein Knowledge Graph, wie ihn etwa Google bei der Inhaltserschließung des Web verwendet (Singhal 2012). Die Entwicklung des Google Knowledge Graph und das hier vorgestellte Protokoll sind historisch miteinander verbunden: OpenRefine wurde ursprünglich als Google Refine entwickelt, und die Funktionalität zum Abgleich mit externen Datenquellen (Reconciliation) wurde ursprünglich zur Einbindung von Freebase entwickelt, einer der Datenquellen des Google Knowledge Graph. Freebase wurde später in Wikidata integriert. Schon Google Refine wurde zum Abgleich mit Normdaten verwendet, etwa den Library of Congress Subject Headings (Hooland et al. 2013).

    Abstract
    In diesem Artikel wird ein Re-Ranking-Ansatz für Suchsysteme vorgestellt, der die Recherche nach wissenschaftlicher Literatur messbar verbessern kann. Das nichttextorientierte Rankingverfahren Bradfordizing wird eingeführt und anschließend im empirischen Teil des Artikels bzgl. der Effektivität für typische fachbezogene Recherche-Topics evaluiert. Dem Bradford Law of Scattering (BLS), auf dem Bradfordizing basiert, liegt zugrunde, dass sich die Literatur zu einem beliebigen Fachgebiet bzw. -thema in Zonen unterschiedlicher Dokumentenkonzentration verteilt. Dem Kernbereich mit hoher Konzentration der Literatur folgen Bereiche mit mittlerer und geringer Konzentration. Bradfordizing sortiert bzw. rankt eine Dokumentmenge damit nach den sogenannten Kernzeitschriften. Der Retrievaltest mit 164 intellektuell bewerteten Fragestellungen in Fachdatenbanken aus den Bereichen Sozial- und Politikwissenschaften, Wirtschaftswissenschaften, Psychologie und Medizin zeigt, dass die Dokumente der Kernzeitschriften signifikant häufiger relevant bewertet werden als Dokumente der zweiten Dokumentzone bzw. den Peripherie-Zeitschriften. Die Implementierung von Bradfordizing und weiteren Re-Rankingverfahren liefert unmittelbare Mehrwerte für den Nutzer.

    Abstract
    Die Interoperabilität von Metadaten ist eine wichtige Voraussetzung für das Generieren von Information und Wissen in einer vernetzten Welt. Aus diesem Grund entstehen seit Mitte der Neunziger Jahre verschiedene Standards mit dem Ziel, die Interoperabilität von Metadaten zu erhöhen. Genannt seien hier vor allem DCMES und DCAM, RDF und SKOS. Aufgabe von KIM ist es, diese Entwicklungen zu begleiten und in die deutschsprachige Community zu tragen. Dabei bietet KIM neben reinen Informationsangeboten (z. B. in Form von Übersetzungen, Vorträgen und Handreichungen) auch konkrete Unterstützung in Form von Schulungen und Beratungen an.

    Abstract
    The semantic heterogeneity presented by Web information in the Agricultural domain presents tremendous information retrieval challenges. This article presents work taking place at the Food and Agriculture Organizations (FAO) which addresses this challenge. Based on the analysis of resources in the domain of agriculture, this paper proposes (a) an application profile (AP) for dealing with the problem of heterogeneity originating from differences in terminologies, domain coverage, and domain modelling, and (b) a root application ontology (AAO) based on the application profile which can serve as a basis for extending knowledge of the domain. The paper explains how even a small investment in the enhancement of relations between vocabularies, both metadata and domain-specific, yields a relatively large return on investment.
