    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
    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
    In this presentation, we therefore focus on a solution for providing uniform access to Digital Libraries and other online services. In order to enable uniform query access to heterogeneous sources, we must provide metadata interoperability in a way that a query language - in this case SPARQL - can cope with the incompatibility of the metadata in various sources without changing their already existing information models.

    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.

    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
    During the years 2006 and 2007, the BnF has collaborated with the National Library of the Netherlands within the framework of the Dutch project STITCH. This project, through concrete experiments, investigates semantic interoperability, especially in relation to searching. How can we conduct semantic searches across several digital heritage collections? The metadata related to content analysis are often heterogeneous. Beyond using manual mapping of semantically similar entities, STITCH explores the techniques of the semantic web, particularly ontology mapping. This paper is about an experiment made on two digital iconographic collections: Mandragore, iconographic database of the Manuscript Department of the BnF, and the Medieval Illuminated manuscripts collection of the KB. While the content of these two collections is similar, they have been processed differently and the vocabularies used to index their content is very different. Vocabularies in Mandragore and Iconclass are both controlled and hierarchical but they do not have the same semantic and structure. This difference is of particular interest to the STITCH project, as it aims to study automatic alignment of two vocabularies. The collaborative experiment started with a precise analysis of each of the vocabularies; that included concepts and their representation, lexical properties of the terms used, semantic relationships, etc. The team of Dutch researchers then studied and implemented mechanisms of alignment of the two vocabularies. The initial models being different, there had to be a common standard in order to enable procedures of alignment. RDF and SKOS were selected for that. The experiment lead to building a prototype that allows for querying in both databases at the same time through a single interface. The descriptors of each vocabulary are used as search terms for all images regardless of the collection they belong to. This experiment is only one step in the search for solutions that aim at making navigation easier between heritage collections that have heterogeneous metadata.

    Abstract
    The paper describes a project to add value to controlled vocabularies by making inter-vocabulary associations. A methodology for mapping terms from one vocabulary to another is presented in the form of a case study applying the approach to the Educational Resources Information Center (ERIC) Thesaurus and the Library of Congress Subject Headings (LCSH). Our approach to mapping involves encoding vocabularies according to Machine-Readable Cataloging (MARC) standards, machine matching of vocabulary terms, and categorizing candidate mappings by likelihood of valid mapping. Mapping data is then stored as machine links. Vocabularies with associations to other schemes will be a key component of Web-based terminology services. The paper briefly describes how the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is used to provide access to a vocabulary with mappings.

    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
    Digital Libraries currently face the challenge of integrating many different types of research information (e.g. publications, primary data, expert's profiles, institutional profiles, project information etc.) according to their scientific users' needs. To date no general, integrated model for knowledge organization and retrieval in Digital Libraries exists. This causes the problem of structural and semantic heterogeneity due to the wide range of metadata standards, indexing vocabularies and indexing approaches used for different types of information. The research presented in this paper focuses on areas in which activities are being undertaken in the field of Digital Libraries in order to treat semantic interoperability problems. We present a model for the integrated retrieval of factual and textual data which combines multiple approaches to semantic interoperability und sets them into context. Embedded in the research cycle, traditional content indexing methods for publications meet the newer, but rarely used ontology-based approaches which seem to be better suited for representing complex information like the one contained in survey data. The benefits of our model are (1) easy re-use of available knowledge organisation systems and (2) reduced efforts for domain modelling with ontologies.

    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
    The one-year pilot project Methodology for mapping Humord to WebDewey at the University of Oslo Library (henceforth abbreviated UiO Library) was a sub-project of the larger project Towards a general Norwegian thesaurus? The results of the project were reported to the National Library of Norway in March. The project has received new funding and is prolonged as the two-year project Mapping to Norwegian WebDewey. The present document provides a presentation of the mapping project at the UiO Library, at the point when we closed the pilot and continued our efforts in the prolonged project. The paper is largely a translation of the pilot project report as per March 1st 2015, enriched with some updates and comments. It is indeed an intellectual work in progress, so the discussions, opinions and solutions presented below are under constant debate and review in our project group. This "state of the art" description of our challenges in mapping a thesaurus to WebDewey is intended as a starting point for our joint discussions at the EDUG seminar in Naples.

    Abstract
    Der Aufbau der Europäischen Digitalen Bibliothek wurde im Herbst 2007 auf soliden Grund gestellt: Mit der European Digital Library Foundation steht eine geschäftsfähige Organisation als Trägerin der Europäischen Digitalen Bibliothek zur Verfügung. Sie fungiert zunächst als Steuerungsgremium für das EU-finanzierte Projekt EDLnet und übernimmt sukzessive die Aufgaben, die für den Aufbau und die Weiterentwicklung der Europäischen Digitalen Bibliothek notwendig sind. Die Gründungsmitglieder sind zehn europäische Dachorganisationen aus den Bereichen Bibliothek, Archiv, audiovisuelle Sammlungen und Museen. Vorstandsmitglieder sind die Vorsitzende Elisabeth Niggemann (CENL) die Vize-Vorsitzende Martine de Boisdeffre (EURBICA), der Schatzmeister Edwin van Huis (FIAT) sowie Wim van Drimmelen, der Generaldirektor der Koninklijke Bibliotheek, der Nationalbibliothek der Niederlande, welche die Europäische Digitale Bibliothek hostet. Der Prototyp für die Europäische Digitale Bibliothek wird im Rahmen des EDLnet-Projekts entwickelt. Die erste Version des Prototyps wurde auf der internationalen Konferenz »One more step towards the European Digital Library« vorgestellt, die am 31. Januar und 1. Februar 2008 in der Deutschen Nationalbibliothek (DNB) in Frankfurt am Main stattfand. Die endgültige Version des Prototyps wird im November 2008 von der EU-Kommissarin für Informationsgesellschaft und Medien, Viviane Reding, in Paris vorgestellt werden. Dieser Prototyp wird direkten Zugang zu mindestens zwei Mio. digitalisierten Büchern, Fotografien, Karten, Tonaufzeichnungen, Filmaufnahmen und Archivalien aus Bibliotheken, Archiven, audiovisuellen Sammlungen und Museen Europas bieten.

    Abstract
    Purpose - To demonstrate that newer developments in the semantic web community, particularly those based on ontologies (simple knowledge organization system and others) mitigate common arguments from the digital library (DL) community against participation in the Semantic web. Design/methodology/approach - The approach is a semantic web discussion focusing on the weak structure of the Web and the lack of consideration given to the semantic content during indexing. Findings - The points criticised by the semantic web and ontology approaches are the same as those of the DL "Shell model approach" from the mid-1990s, with emphasis on the centrality of its heterogeneity components (used, for example, in vascoda). The Shell model argument began with the "invisible web", necessitating the restructuring of DL approaches. The conclusion is that both approaches fit well together and that the Shell model, with its semantic heterogeneity components, can be reformulated on the semantic web basis. Practical implications - A reinterpretation of the DL approaches of semantic heterogeneity and adapting to standards and tools supported by the W3C should be the best solution. It is therefore recommended that - although most of the semantic web standards are not technologically refined for commercial applications at present - all individual DL developments should be checked for their adaptability to the W3C standards of the semantic web. Originality/value - A unique conceptual analysis of the parallel developments emanating from the digital library and semantic web communities.

    Abstract
    Digital cultural heritage resources are widely available on the web through the digital libraries of heritage institutions. To address the difficulties of discoverability in cultural heritage, the common practice is metadata aggregation, where centralized efforts like Europeana facilitate discoverability by collecting the resources' metadata. We present the results of the linked data aggregation task conducted within the Europeana Common Culture project, which attempted an innovative approach to aggregation based on linked data made available by cultural heritage institutions. This task ran for one year with participation of eleven organizations, involving the three member roles of the Europeana network: data providers, intermediary aggregators, and the central aggregation hub, Europeana. We report on the challenges that were faced by data providers, the standards and specifications applied, and the resulting aggregated metadata.

    Abstract
    Cultural heritage institutions are publishing their digital collections over the web as LOD. This is is a new step in the patrimonialization and curatorial processes developed by such institutions. Many of these collections are thematically superimposed and complementary. Frequently, objects in these collections present culturally relevant relationships, such as a book about a painting, or a draft or sketch of a famous painting, etc. LOD technology enables such heritage records to be interlinked, achieving interoperability and adding value to digital collections, thus empowering heritage institutions. An aim of this research is characterizing such culturally relevant relationships and organizing them in a vocabulary. Use cases or examples of relationships between objects suggested by curators or mentioned in literature and in the conceptual models as FRBR/LRM, CIDOC CRM and RiC-CM, were collected and used as examples or inspiration of cultural relevant relationships. Relationships identified are collated and compared for identifying those with the same or similar meaning, synthesized and normalized. A set of thirty-three culturally relevant relationships are identified and formalized as a LOD property vocabulary to be used by digital curators to interlink digital collections. The results presented are provisional and a starting point to be discussed, tested, and enhanced.

    Abstract
    The MACS project aims at providing multilingual subject access to library catalogues through the use of concordances between subject headings from LCSH, RAMEAU and SWD. The manual approach, as used by MACS, has been up to now the most reliable method for ensuring accurate multilingual subject access to bibliographic data. The presentation will give an overview on the development of the project and will outline the strategy and methods used by the MACS project. The presentation will also include a demonstration of the search interface developed by The European Library (TEL).

    Abstract
    The concept of Linked Data has been an emerging theme within the computing and digital heritage areas in recent years. The growth and scale of Linked Data has underlined the need for greater commonality in concept referencing, to avoid local redefinition and duplication of reference resources. Achieving domain-wide agreement on common vocabularies would be an unreasonable expectation; however, datasets often already have local vocabulary resources defined, and so the prospects for large-scale interoperability can be substantially improved by creating alignment links from these local vocabularies out to common external reference resources. The ARIADNE project is undertaking large-scale integration of archaeology dataset metadata records, to create a cross-searchable research repository resource. Key to enabling this cross search will be the 'subject' metadata originating from multiple data providers, containing terms from multiple multilingual controlled vocabularies. This paper discusses various aspects of vocabulary mapping. Experience from the previous SENESCHAL project in the publication of controlled vocabularies as Linked Open Data is discussed, emphasizing the importance of unique URI identifiers for vocabulary concepts. There is a need to align legacy indexing data to the uniquely defined concepts and examples are discussed of SENESCHAL data alignment work. A case study for the ARIADNE project presents work on mapping between vocabularies, based on the Getty Art and Architecture Thesaurus as a central hub and employing an interactive vocabulary mapping tool developed for the project, which generates SKOS mapping relationships in JSON and other formats. The potential use of such vocabulary mappings to assist cross search over archaeological datasets from different countries is illustrated in a pilot experiment. The results demonstrate the enhanced opportunities for interoperability and cross searching that the approach offers.

    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.
