    Abstract
    Although service-oriented architectures go a long way toward providing interoperability in distributed, heterogeneous environments, managing semantic differences in such environments remains a challenge. We give an overview of the issue of semantic interoperability (integration), provide a semantic characterization of services, and discuss the role of ontologies. Then we analyze four basic models of semantic interoperability that differ in respect to their mapping between service descriptions and ontologies and in respect to where the evaluation of the integration logic is performed. We also provide some guidelines for selecting one of the possible interoperability models.

    Abstract
    In recent years, cultural heritage institutions have been exploring the benefits of applying Linked Open Data to their catalogs and digital materials. Innovative and creative methods have emerged to publish and reuse digital contents to promote computational access, such as the concepts of Labs and Collections as Data. Data quality has become a requirement for researchers and training methods based on artificial intelligence and machine learning. This article explores how the quality of Linked Open Data made available by cultural heritage institutions can be automatically assessed. The results obtained can be useful for other institutions who wish to publish and assess their collections.

    Abstract
    Terminology registries (TRs) are a crucial element of the infrastructure required for resource discovery services, digital libraries, Linked Data, and semantic interoperability generally. They can make the content of knowledge organization systems (KOS) available both for human and machine access. The paper describes the attributes and functionality for a TR, based on a review of published literature, existing TRs, and a survey of experts. A domain model based on user tasks is constructed and a set of core metadata elements for use in TRs is proposed. Ideally, the TR should allow searching as well as browsing for a KOS, matching a user's search while also providing information about existing terminology services, accessible to both humans and machines. The issues surrounding metadata for KOS are also discussed, together with the rationale for different aspects and the importance of a core set of KOS metadata for future machine-based access; a possible core set of metadata elements is proposed. This is dealt with in terms of practical experience and in relation to the Dublin Core Application Profile.

    Abstract
    Smart applications behave intelligently because they understand at least partially the context where they operate. To do this, they need not only a formal domain model but also formal descriptions of the data they process and their own operational behaviour. Interoperability of smart applications is based on formalised definitions of all their data and processes. This paper studies the semantic interoperability of data in the case of eLearning and describes an experiment and its assessment. New content is imported into a knowledge-based learning environment without real updates of the original domain model, which is encoded as a knowledge base of conceptual graphs. A component called mediator enables the import by assigning dummy metadata annotations for the imported items. However, some functionality of the original system is lost, when processing the imported content, due to the lack of proper metadata annotation which cannot be associated fully automatically. So the paper presents an interoperability scenario when appropriate content items are viewed from the perspective of the original world and can be (partially) reused there.

    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
    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
    Mit zunehmender Nutzung netzwerkbasierter Systeme und steigender internationaler Zusammenarbeit werden Informationsräume geschaffen, in denen unterschiedlich indexierte Informationsressourcen aus verschiedenen Ländern über das Internet frei zugänglich gemacht werden. Bedingt durch die Unterschiedlichkeit der verwendeten Erschließungsinstrumente in Sprache und Struktur gestaltet sich die thematische Recherche in diesen Informationsräumen umständlich und langwierig. Im Rahmen des von der Deutschen Forschungsgemeinschaft (DFG) geförderten und von der Deutschen Nationalbibliothek (DNB) in Kooperation mit der Fachhochschule Köln durchgeführten Projekts CrissCross wird ein multilinguales, thesaurusbasiertes und benutzergerechtes Recherchevokabular erstellt, das einen wesentlich effizienteren Zugriff auf heterogen erschlossene Informationsressourcen ermöglicht.

    Abstract
    Am 29. und 30. Oktober 2009 fand in der Königlichen Bibliothek in Den Haag das zweite internationale UDC-Seminar zum Thema "Classification at a Crossroad" statt. Organisiert wurde diese Konferenz - wie auch die erste Konferenz dieser Art im Jahr 2007 - vom UDC-Konsortium (UDCC). Im Mittelpunkt der diesjährigen Veranstaltung stand die Erschließung des World Wide Web unter besserer Nutzung von Klassifikationen (im Besonderen natürlich der UDC), einschließlich benutzerfreundlicher Repräsentationen von Informationen und Wissen. Standards, neue Technologien und Dienste, semantische Suche und der multilinguale Zugriff spielten ebenfalls eine Rolle. 135 Teilnehmer aus 35 Ländern waren dazu nach Den Haag gekommen. Das Programm umfasste mit 22 Vorträgen aus 14 verschiedenen Ländern eine breite Palette, wobei Großbritannien mit fünf Beiträgen am stärksten vertreten war. Die Tagesschwerpunkte wurden an beiden Konferenztagen durch die Eröffnungsvorträge gesetzt, die dann in insgesamt sechs thematischen Sitzungen weiter vertieft wurden.

    Abstract
    Das BMBF hat bis Ende 2007 ein Projekt gefördert, dessen Aufgabe es war, die Erstellung und das Management von Crosskonkordanzen zwischen kontrollierten Vokabularen (Thesauri, Klassifikationen, Deskriptorenlisten) zu organisieren. In drei Jahren wurden 64 Crosskonkordanzen mit mehr als 500.000 Relationen zwischen kontrollierten Vokabularen aus den Sozialwissenschaften und anderen Fachgebieten umgesetzt. In der Schlussphase des Projekts wurde eine umfangreiche Evaluation durchgeführt, die die Effektivität der Crosskonkordanzen in unterschiedlichen Informationssystemen testen sollte. Der Artikel berichtet über die Anwendungsmöglichkeiten der Heterogenitätsbehandlung durch Crosskonkordanzen und die Ergebnisse der umfangreichen Analysen.

    Abstract
    The paper reports about results on the GESIS-IZ project "Competence Center Modeling and Treatment of Semantic Heterogeneity" (KoMoHe). KoMoHe supervised a terminology mapping effort, in which 'cross-concordances' between major controlled vocabularies were organized, created and managed. In this paper we describe the establishment and implementation of crossconcordances for search in a digital library (DL).

    Abstract
    The CACAO Project (Cross-language Access to Catalogues and Online Libraries) has been designed to implement natural language processing and cross-language information retrieval techniques to provide cross-language access to information in libraries, a critical issue in the linguistically diverse European Union. This project report addresses two metadata-related challenges for the library community in this context: "false friends" (identical words having different meanings in different languages) and term ambiguity. The possible solutions involve enriching the metadata with attributes specifying language or the source authority file, or associating potential search terms to classes in a classification system. The European Library will evaluate an early implementation of this work in late 2008.

    Abstract
    One of the major problems facing systems for Computer Aided Design (CAD), Architecture Engineering and Construction (AEC) and Geographic Information Systems (GIS) applications today is the lack of interoperability among the various systems. When integrating software applications, substantial di culties can arise in translating information from one application to the other. In this paper, we focus on semantic di culties that arise in software integration. Applications may use di erent terminologies to describe the same domain. Even when appli-cations use the same terminology, they often associate di erent semantics with the terms. This obstructs information exchange among applications. To cir-cumvent this obstacle, we need some way of explicitly specifying the semantics for each terminology in an unambiguous fashion. Ontologies can provide such specification. It will be the task of this paper to explain what ontologies are and how they can be used to facilitate interoperability between software systems used in computer aided design, architecture engineering and construction, and geographic information processing.

    Abstract
    To make better use of knowledge organization systems (KOS) for query expansion, we have developed a pattern-based technique for composition ontology mapping in a specific domain. The technique was tested in a two-step mapping. The user's free-text queries were first mapped to Getty's Art & Architecture Thesaurus (AAT) terms. The AAT-based queries were then mapped to a search engine's indexing vocabulary (ARTstor terms). The result indicated that our technique has improved the mapping success rate from 40% to 70%. We discuss also how the technique may be applied to other KOS mapping and how it may be implemented in practical systems.

    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
    Thesaurus-Crosskonkordanzen bilden eine wichtige Voraussetzung für die integrierte Suche in einer verteilten Datenstruktur. Ihr Aufbau erfordert allerdings erhebliche personelle Ressourcen. Der vorliegende Beitrag liefert Evaluationsergebnisse des Library Track 2012 der Ontology Alignment Evaluation Initiative (OAEI), in dem Crosskonkordanzen zwischen dem Thesaurus Sozialwissenschaften (TheSoz) und dem Standard Thesaurus Wirtschaft (STW) erstmals automatisch erstellt wurden. Die Evaluation weist auf deutliche Unterschiede in den getesteten Matching- Tools hin und stellt die qualitativen Unterschiede einer automatisch im Vergleich zu einer intellektuell erstellten Crosskonkordanz heraus. Die Ergebnisse sprechen für einen Einsatz automatisch generierter Thesaurus-Crosskonkordanzen, um Domänenexperten eine maschinell erzeugte Vorselektion von möglichen Äquivalenzrelationen anzubieten.

    Abstract
    Die Verwendung von Erschließungsinstrumenten zur Beschreibung von Informationsressourcen kann Effizienz und Effektivität thematischer Recherchen wesentlich steigern: standardisierte Begriffe unterstützen Recall und Precision begrifflicher Suchen; Ausweisung von Relationen bietet die Grundlage für explorative Suchprozesse. Eine zusätzliche Steigerung der Funktionalitäten des Retrievals kann mittels einer Ausdifferenzierung und Spezifizierung der in Normdaten enthaltenen semantischen Informationen erreicht werden, die über die in Thesauri und Klassifikationen verbreiteten grundlegenden Relationstypen (äquivalent, hierarchisch, assoziativ) hinausgehen. In modernen Informationsräumen, in denen Daten verschiedener Institutionen über eine Plattform zeit- und ortsunabhängig zugänglich gemacht werden, können einzelne Wissenssysteme indes nur unzureichend das Information Retrieval unterstützen. Zu unterschiedlich sind die für thematische Suchanfragen relevanten Indexierungsdaten. Eine Verbesserung kann mittels Herstellung von Interoperabilität zwischen den verschiedenen Dokumentationssprachen erreicht werden. Im Vortrag wird dargelegt, in welcher Art und Weise die in Wissenssystemen enthaltenen semantischen Informationen zur Unterstützung thematischer Recherchen optimiert werden können und inwiefern Interoperabilität zwischen Systemen geschaffen werden kann, die gleichwertige Funktionalitäten in heterogenen Informationsräumen gewährleisten. In diesem Zusammenhang wird auch auf aktuelle Mappingprojekte wie das DFG-Projekt CrissCross oder das RESEDA-Projekt, welches sich mit den Möglichkeiten der semantischen Anreicherung bestehender Dokumentationssprachen befasst, eingegangen.

    Abstract
    This paper is about a better understanding of the structure and dynamics of science and the usage of these insights for compensating the typical problems that arises in metadata-driven Digital Libraries. Three science model driven retrieval services are presented: co-word analysis based query expansion, re-ranking via Bradfordizing and author centrality. The services are evaluated with relevance assessments from which two important implications emerge: (1) precision values of the retrieval services are the same or better than the tf-idf retrieval baseline and (2) each service retrieved a disjoint set of documents. The different services each favor quite other - but still relevant - documents than pure term-frequency based rankings. The proposed models and derived retrieval services therefore open up new viewpoints on the scientific knowledge space and provide an alternative framework to structure scholarly information systems.
