    Abstract
    This paper gives a comprehensive overview over the problem of Semantic Interoperability in the Cultural Heritage domain, with a particular focus on solutions centered around extensional, i.e., instance-based, ontology matching methods. It presents three typical scenarios requiring interoperability, one with homogenous collections, one with heterogeneous collections, and one with multi-lingual collection. It discusses two different ways to evaluate potential alignments, one based on the application of re-indexing, one using a reference alignment. To these scenarios we apply extensional matching with different similarity measures which gives interesting insights. Finally, we firmly position our work in the Cultural Heritage context through an extensive discussion of the relevance for, and issues related to this specific field. The findings are as unspectacular as expected but nevertheless important: the provided methods can really improve interoperability in a number of important cases, but they are not universal solutions to all related problems. This paper will provide a solid foundation for any future work on Semantic Interoperability in the Cultural Heritage domain, in particular for anybody intending to apply extensional methods.

    Abstract
    The modern Web has grown from a publishing place of well-structured data and HTML pages for companies and experienced users into a vivid publishing and data exchange community in which everyone can participate, both as a data consumer and as a data producer. Unavoidably, the data available on the Web became highly heterogeneous, ranging from highly structured and semistructured to highly unstructured user-generated content, reflecting different perspectives and structuring principles. The full potential of such data can only be realized by combining information from multiple sources. For instance, the knowledge that is typically embedded in monolithic applications can be outsourced and, thus, used also in other applications. Numerous systems nowadays are already actively utilizing existing content from various sources such as WordNet or Wikipedia. Some well-known examples of such systems include DBpedia, Freebase, Spock, and DBLife. A major challenge during combining and querying information from multiple heterogeneous sources is entity linkage, i.e., the ability to detect whether two pieces of information correspond to the same real-world object. This chapter introduces a novel approach for addressing the entity linkage problem for heterogeneous, uncertain, and volatile data.

    Abstract
    Logic and precision are fundamental to ontologies underlying the semantic web and, by extension, to linked data. This special section focuses on the interaction of semantics, ontologies and linked data. The discussion presents the Simple Knowledge Organization Scheme (SKOS) as a less formal strategy for expressing concept hierarchies and associations and questions the value of deep domain ontologies in favor of simpler vocabularies that are more open to reuse, albeit risking illogical outcomes. RDF ontologies harbor another unexpected drawback. While structurally sound, they leave validation gaps permitting illogical uses, a problem being addressed by a W3C Working Group. Data models based on RDF graphs and properties may replace traditional library catalog models geared to predefined entities, with relationships between RDF classes providing the semantic connections. The BIBFRAME Initiative takes a different and streamlined approach to linking data, building rich networks of information resources rather than relying on a strict underlying structure and vocabulary. Taken together, the articles illustrate the trend toward a pragmatic approach to a Semantic Web, sacrificing some specificity for greater flexibility and partial interoperability.

    Abstract
    This article 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 article 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 Dewey Decimal Classification [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
    In Digitalen Bibliotheken als integrierten Zugängen zu in der Regel mehreren verschiedenen Dokumentsammlungen tritt Heterogenität in vielerlei Spielarten auf: - als technische Heterogenität durch das Zusammenspiel verschiedener Betriebs-, Datenbank- oder Softwaresysteme, - als strukturelle Heterogenität durch das Auftreten verschiedener Dokumentstrukturen und Metadaten-Standards und schließlich - als semantische Heterogenität, wenn Dokumente mit Hilfe unterschiedlicher Ontologien (hier verwendet im weiteren Sinn von Dokumentationssprachen wie Thesauri und Klassifikationen) erschlossen wurden oder aber Dokumente überhaupt nicht mit Metadaten ausgezeichnet wurden. Semantische Heterogenität lässt sich behandeln, indem die Standardisierung von Metadaten (z.B. von der Dublin Core Metadata Initiative oder das Resource Description Framework (RDF) im Kontext des Semantic Web) vorangetrieben und ihre Verwendung gefördert wird. Allerdings besteht auf Grund der unterschiedlichen Interessen aller beteiligten Partner (u.a. Bibliotheken, Dokumentationsstellen, Datenbankproduzenten, "freie" Anbieter von Dokumentsammlungen und Datenbanken) kaum die Aussicht, dass sich durch diese Standardisierung semantische Heterogenität restlos beseitigen lässt. Insbesondere ist eine einheitliche Verwendung von Vokabularen und Ontologien nicht in Sicht. Im Projekt CARMEN wurde unter anderem das Problem der semantischen Heterogenität einerseits durch die automatische Extraktion von Metadaten aus Internetdokumenten und andererseits durch Systeme zur Transformation von Anfragen über Cross-Konkordanzen und statistisch erzeugte Relationen angegangen. Ein Teil der Ergebnisse der Arbeiten am IZ Sozialwissenschaften waren statistische Relationen zwischen Deskriptoren, die mittels Kookurrenzbeziehungen berechnet wurden. Diese Relationen wurden dann für die Übersetzung von Anfragen genutzt, um zwischen verschiedenen Ontologien oder auch Freitexttermen zu vermitteln. Das Ziel dieser Übersetzung ist die Verbesserung des (automatischen) Überstiegs zwischen unterschiedlich erschlossenen Dokumentbeständen, z.B. Fachdatenbanken und Internetdokumenten, als Lösungsansatz zur Behandlung semantischer Heterogenität.
