    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
    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
    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
    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.

    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
    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
    An issue currently at the forefront of digital library research is the prevalence of disparate terminologies and the associated limitations imposed on user searching. It is thought that semantic interoperability is achievable by improving the compatibility between terminologies and classification schemes, enabling users to search multiple resources simultaneously and improve retrieval effectiveness through the use of associated terms drawn from several schemes. This column considers the terminology issue before outlining various proposed methods of tackling it, with a particular focus on terminology mapping.

    Abstract
    Purpose - To show how semantic web techniques can help address semantic interoperability issues in the broad cultural heritage domain, allowing users an integrated and seamless access to heterogeneous collections. Design/methodology/approach - This paper presents the heterogeneity problems to be solved. It introduces semantic web techniques that can help in solving them, focusing on the representation of controlled vocabularies and their semantic alignment. It gives pointers to some previous projects and experiments that have tried to address the problems discussed. Findings - Semantic web research provides practical technical and methodological approaches to tackle the different issues. Two contributions of interest are the simple knowledge organisation system model and automatic vocabulary alignment methods and tools. These contributions were demonstrated to be usable for enabling semantic search and navigation across collections. Research limitations/implications - The research aims at designing different representation and alignment methods for solving interoperability problems in the context of controlled subject vocabularies. Given the variety and technical richness of current research in the semantic web field, it is impossible to provide an in-depth account or an exhaustive list of references. Every aspect of the paper is, however, given one or several pointers for further reading. Originality/value - This article provides a general and practical introduction to relevant semantic web techniques. It is of specific value for the practitioners in the cultural heritage and digital library domains who are interested in applying these methods in practice.

    Abstract
    As an important support tool in science research, specialized information systems are rapidly changing their character. The potential for improvement compared with today's usual systems is enormous. This fact will be demonstrated by means of two problem complexes: - WWW search engines, which were developed without any government grants, are increasingly dominating the scene. Does the WWW displace information centers with their high quality databases? What are the results we can get nowadays using general WWW search engines? - In addition to the WWW and specialized databases, scientists now use WWW library catalogues of digital libraries, which combine the catalogues from an entire region or a country. At the same time, however, they are faced with highly decentralized heterogeneous databases which contain the widest range of textual sources and data, e.g. from surveys. One consequence is the presence of serious inconsistencies in quality, relevance and content analysis. Thus, the main problem to be solved is as follows: users must be supplied with heterogeneous data from different sources, modalities and content development processes via a visual user interface without inconsistencies in content development, for example, seriously impairing the quality of the search results, e. g. when phrasing their search inquiry in the terminology to which they are accustomed

    Abstract
    The need for improved semantic in teroperability between and among vocabularies and knowledge organization schemes is undeniable and growing in importance. There is an ever-increasing need to create an environment by which even multiple portals could be accessed via subject metadata using software that is neutral and available ubiquitously or directly to the user, that could be copied by libraries for use in their own environment. In order to develop or improve a knowledge organization system including emerging options in semantic interoperability, scholars and practitioners need to be able to evaluate a wide variety of projects and stay current with the professional literature. Based on its findings, the Subcommittee concludes that the development of a successful subject semantic interoperability project is a long and difficult process. It requires a substantial investment of financial, human and computer resources. The Subcommittee recommends using the information and tools in this report and its appendices to assist in developing a successful project incorporating subject semantic interoperability. Finally the Subcommittee concludes that since this field of endeavor is still relatively young and immature, it is too early to generate a set of Best Practices that could be used in developing a successful project. We are past the theoretical and basic research phase and into the development phase. Even though there are some successful projects in full production, more projects need to reach maturity and much more research needs to be done.

    Abstract
    The HILT Phase II project aimed to develop a pilot terminologies server with a view to improving cross-sectoral information retrieval. In order to inform this process, it was first necessary to examine how a representative group of users approached a range of information-related tasks. This paper focuses on exploratory interviews conducted to investigate the proposed ideal and actual strategies of a group of 30 users in relation to eight separate information tasks. In addition, users were asked to give examples of search terms they may employ and to describe how they would formulate search queries in each scenario. The interview process undertaken and the results compiled are outlined, and associated implications for the development of a pilot terminologies server are discussed.

    Abstract
    The German Federal Ministry for Education and Research funded a major terminology mapping initiative, which found its conclusion in 2007. The task of this terminology mapping initiative was to organize, create and manage 'cross-concordances' between controlled vocabularies (thesauri, classification systems, subject heading lists) centred around the social sciences but quickly extending to other subject areas. 64 crosswalks with more than 500,000 relations were established. In the final phase of the project, a major evaluation effort to test and measure the effectiveness of the vocabulary mappings in an information system environment was conducted. The paper reports on the cross-concordance work and evaluation results.
