    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
    Das Problem der mehrsprachigen Suche gewinnt in der letzten Zeit immer mehr an Bedeutung, da viele nützliche Fachinformationen in der Welt in verschiedenen Sprachen publiziert werden. RSWBPlus ist eine bibliographische Datenbank zum Nachweis der Fachliteratur im Bereich Planen und Bauen, welche deutsch- und englischsprachige Metadaten-Einträge enthält. Bis vor Kurzem war es problematisch Einträge zu finden, deren Sprache sich von der Anfragesprache unterschied. Zum Beispiel fand man auf deutschsprachige Anfragen nur deutschsprachige Einträge, obwohl die Datenbank auch potenziell nützliche englischsprachige Einträge enthielt. Um das Problem zu lösen, wurde nach einer Untersuchung bestehender Ansätze, die RSWBPlus weiterentwickelt, um eine mehrsprachige (sprachübergreifende) Suche zu unterstützen, welche unter Einbeziehung eines zweisprachigen begriffbasierten Thesaurus erfolgt. Der Thesaurus wurde aus bereits bestehenden Thesauri automatisch gebildet. Die Einträge der Quell-Thesauri wurden in SKOS-Format (Simple Knowledge Organisation System) umgewandelt, automatisch miteinander vereinigt und schließlich in einen Ziel-Thesaurus eingespielt, der ebenfalls in SKOS geführt wird. Für den Zugriff zum Ziel-Thesaurus werden Apache Jena und MS SQL Server verwendet. Bei der mehrsprachigen Suche werden Terme der Anfrage durch entsprechende Übersetzungen und Synonyme in Deutsch und Englisch erweitert. Die Erweiterung der Suchterme kann sowohl in der Laufzeit, als auch halbautomatisch erfolgen. Das verbesserte Recherchesystem kann insbesondere deutschsprachigen Benutzern helfen, relevante englischsprachige Einträge zu finden. Die Verwendung vom SKOS erhöht die Interoperabilität der Thesauri, vereinfacht das Bilden des Ziel-Thesaurus und den Zugriff zu seinen Einträgen.

    Abstract
    Das CrissCross-Projekt verfolgt die Zielsetzung, ein erweitertes multilinguales und thesaurusbasiertes Registervokabular zur Dewey-Dezimalklassifikation (DDC Deutsch) zu erstellen, das als Recherchevokabulars zu heterogen erschlossenen Dokumenten verwendet werden kann und soll damit die Ausgangsbedingungen für die Gestaltung von OPAC-Retrievalumgebungen verbessern helfen. Im einzelnen soll jedes Sachschlagwort der Schlagwortnormdatei (SWD) eine DDC-Notation erhalten und es sollen die im Projekt MACS begonnen Arbeiten fortgesetzt werden, Links zwischen den Schlagwörtern der SWD, den Library of Congress Subject Headings (LCSH) und dem Répertoire d'autorité-matière encyclopédique et alphabétique unifé (Rameau) herzustellen. In diesem Beitrag wird der Vorschlag gemacht, die Zielsetzung des Projektes darin zu sehen, eine Kern-Ontologie mit universalen Relationen als Klassifikation zu benutzen und die beteiligten Normdateien als zugeordnete semantische Netze zu entwickeln, indem nicht-generische Relationen die Aufgabe der durch die Lokalisierung gestellten Anforderungen übernehmen. Generische Relationen im bekannten Thesaurussinn sind für derartige semantische Netze nicht mehr erforderlich, da sie sich aus den generischen Beziehungen der Kern-Ontologie vererben.

    Abstract
    Repositories are web portals that provide access to learning objects. Resources can be easily located through the use of metadata, an important factor to increase the ease of searching for digital resources in repositories. However, there are as yet no similarly effective methods in order to increase access to learning objects. The main goal of this paper is to offer an alternative search system to improve access to academic learning objects and publications for several repositories through the use of information visualisation and Simple Knowledge Organization Schemes (SKOS). To this end, we have developed a visual framework and have used the Organic.Edunet and AGRIS as case studies in order to access academic and scientific publication resources respectively. In this paper, we present the results of our work through a test aimed at evaluating the whole visual framework, and offer recommendations on how to integrate this type of visual search into academic repositories based on SKOS.

    Abstract
    Currently, a number of efforts are being carried out to integrate collections from different institutions and containing heterogeneous material. Examples of such projects are The European Library [1] and the Memory of the Netherlands [2]. A crucial point for the success of these is the availability to provide a unified access on top of the different collections, e.g. using one single vocabulary for querying or browsing the objects they contain. This is made difficult by the fact that the objects from different collections are often described using different vocabularies - thesauri, classification schemes - and are therefore not interoperable at the semantic level. To solve this problem, one can turn to semantic links - mappings - between the elements of the different vocabularies. If one knows that a concept C from a vocabulary V is semantically equivalent to a concept to a concept D from vocabulary W, then an appropriate search engine can return all the objects that were indexed against D for a query for objects described using C. We thus have an access to other collections, using a single one vocabulary. This is however an ideal situation, and hard alignment work is required to reach it. Several projects in the past have tried to implement such a solution, like MACS [3] and Renardus [4]. They have demonstrated very interesting results, but also highlighted the difficulty of aligning manually all the different vocabularies involved in practical cases, which sometimes contain hundreds of thousands of concepts. To alleviate this problem, a number of tools have been proposed in order to provide with candidate mappings between two input vocabularies, making alignment a (semi-) automatic task. Recently, the Semantic Web community has produced a lot of these alignment tools'. Several techniques are found, depending on the material they exploit: labels of concepts, structure of vocabularies, collection objects and external knowledge sources. Throughout our presentation, we will present a concrete heterogeneity case where alignment techniques have been applied to build a (pilot) browser, developed in the context of the STITCH project [5]. This browser enables a unified access to two collections of illuminated manuscripts, using the description vocabulary used in the first collection, Mandragore [6], or the one used by the second, Iconclass [7]. In our talk, we will also make the point for using unified representations the vocabulary semantic and lexical information. Additionally to ease the use of the alignment tools that have these vocabularies as input, turning to a standard representation format helps designing applications that are more generic, like the browser we demonstrate. We give pointers to SKOS [8], an open and web-enabled format currently developed by the Semantic Web community.
