    Abstract
    In the area of semantic technologies, benchmarking and systematic evaluation is not yet as established as in other areas of computer science, e.g., information retrieval. In spite of successful attempts, more effort and experience are required in order to achieve such a level of maturity. In this paper, we report results and lessons learned from the Ontology Alignment Evaluation Initiative (OAEI), a benchmarking initiative for ontology matching. The goal of this work is twofold: on the one hand, we document the state of the art in evaluating ontology matching methods and provide potential participants of the initiative with a better understanding of the design and the underlying principles of the OAEI campaigns. On the other hand, we report experiences gained in this particular area of semantic technologies to potential developers of benchmarking for other kinds of systems. For this purpose, we describe the evaluation design used in the OAEI campaigns in terms of datasets, evaluation criteria and workflows, provide a global view on the results of the campaigns carried out from 2005 to 2010 and discuss upcoming trends, both specific to ontology matching and generally relevant for the evaluation of semantic technologies. Finally, we argue that there is a need for a further automation of benchmarking to shorten the feedback cycle for tool developers.

    Abstract
    Digitale Bibliotheken stehen derzeit vor der Herausforderung, den veränderten Informationsbedürfnissen ihrer wissenschaftlichen Nutzer nachzukommen und einen integrierten Zugriff auf verschiedene Informationsarten (z.B. Publikationen, Primärdaten, Wissenschaftler- und. Organisationsprofile, Forschungsprojektinformationen) zu bieten, die in zunehmenden Maße digital zur Verfügung stehen und diese in virtuellen Forschungsumgebungen verfügbar zu machen. Die daraus resultierende Herausforderungen struktureller und semantischer Heterogenität werden durch ein weites Feld von verschiedenen Metadaten-Standards, Inhaltserschließungsverfahren sowie Indexierungsansätze für verschiedene Arten von Information getragen. Bisher existiert jedoch kein allgemeingültiges, integrierendes Modell für Organisation und Retrieval von Wissen in Digitalen Bibliotheken. Dieser Beitrag stellt aktuelle Forschungsentwicklungen und -aktivitäten vor, die die Problematik der semantischen Interoperabilität in Digitalen Bibliotheken behandeln und präsentiert ein Modell für eine integrierte Suche in textuellen Daten (z.B. Publikationen) und Faktendaten (z.B. Primärdaten), das verschiedene Ansätze der aktuellen Forschung aufgreift und miteinander in Bezug setzt. Eingebettet in den Forschungszyklus treffen dabei traditionelle Inhaltserschließungsverfahren für Publikationen auf neuere ontologie-basierte Ansätze, die für die Repräsentation komplexerer Informationen und Zusammenhänge (z.B. in sozialwissenschaftlichen Umfragedaten) geeigneter scheinen. Die Vorteile des Modells sind (1) die einfache Wiederverwendbarkeit bestehender Wissensorganisationssysteme sowie (2) ein geringer Aufwand bei der Konzeptmodellierung durch Ontologien.

    Abstract
    Currently, several datasets released in a Linked Open Data format are available at a national and international level, but the lack of shared strategies concerning the definition of concepts related to the statistical publishing community makes difficult a comparison among given facts starting from different data sources. In order to guarantee a shared representation framework for what concerns the dissemination of statistical concepts about graduates, we developed SW4AL, an ontology-based system for graduate's surveys domain. The developed system transforms low-level data into an enriched information model and is based on the AlmaLaurea surveys covering more than 90% of Italian graduates. SW4AL: i) semantically describes the different peculiarities of the graduates; ii) promotes the structured definition of the AlmaLaurea data and the following publication in the Linked Open Data context; iii) provides their reuse in the open data scope; iv) enables logical reasoning about knowledge representation. SW4AL establishes a common semantic for addressing the concept of graduate's surveys domain by proposing the creation of a SPARQL endpoint and a Web based interface for the query and the visualization of the structured data.

    Abstract
    Current retrieval and recommendation approaches rely on hard-wired data models. This hinders personalized cus-tomizations to meet information needs of users in a more flexible manner. Therefore, the paper investigates how similarity-basedretrieval strategies can be combined with graph queries to enable users or system providers to explore repositories in the LinkedOpen Data (LOD) cloud more thoroughly. For this purpose, we developed novel content-based recommendation approaches.They rely on concept annotations of Simple Knowledge Organization System (SKOS) vocabularies and a SPARQL-based querylanguage that facilitates advanced and personalized requests for openly available knowledge graphs. We have comprehensivelyevaluated the novel search strategies in several test cases and example application domains (i.e., travel search and multimediaretrieval). The results of the web-based online experiments showed that our approaches increase the recall and diversity of rec-ommendations or at least provide a competitive alternative strategy of resource access when conventional methods do not providehelpful suggestions. The findings may be of use for Linked Data-enabled recommender systems (LDRS) as well as for semanticsearch engines that can consume LOD resources.

    Abstract
    A pidgin metadata framework based on the concept of pidgin metadata is proposed to complement the limitations of existing approaches to metadata interoperability and to achieve more reliable metadata interoperability. The framework consists of three layers, with a hierarchical structure, and reflects the semantic and structural characteristics of various metadata. Layer 1 performs both an external function, serving as an anchor for semantic association between metadata elements, and an internal function, providing semantic categories that can encompass detailed elements. Layer 2 is an arbitrary layer composed of substantial elements from existing metadata and performs a function in which different metadata elements describing the same or similar aspects of information resources are associated with the semantic categories of Layer 1. Layer 3 implements the semantic relationships between Layer 1 and Layer 2 through the Resource Description Framework syntax. With this structure, the pidgin metadata framework can establish the criteria for semantic connection between different elements and fully reflect the complexity and heterogeneity among various metadata. Additionally, it is expected to provide a bibliographic environment that can achieve more reliable metadata interoperability than existing approaches by securing the communication between metadata.

    ""Sacherschließung - Informationsdienstleistung nach Maß": unter diesem Titel fand am 3. Leipziger Kongress für Information und Bibliothek ("Information und Ethik") eine sehr aufschlussreiche Vortragsreihe statt. Neue Projekte der Vernetzung unterschiedlichst erschlossener Bestände wurden vorgestellt. Auch die Frage, inwieweit man die Nutzerinnen und Nutzer in die Erschließung einbinden kann, wurde behandelt. Die Arbeit der Bibliothekare kann wertvolle Ausgangssituationen für alternative Methoden bieten. Das Zusammenwirken von intellektueller und maschineller Erschließung wird in Zukunft eine große Rolle spielen. Ein Ausweg, um die Erschließung der ständig wachsenden Informationsquellen zu ermöglichen, könnte eine arbeitsteilige Erschließung und eine Kooperation mit anderen Informationseinrichtungen darstellen. Im Mittelpunkt all dieser Überlegungen standen die Heterogenitätsprobleme, die sich durch unterschiedliche Erschließungsregeln, verschiedene Arbeitsinstrumente, verschiedene Sprachen und durch die unterschiedliche Bedeutung der Begriffe ergeben können. Der Nachmittag begann mit einem konkreten Beispiel: "Zum Stand der Heterogenitätsbehandlung in vascoda" (Philipp Mayr, Bonn und Anne-Kathrin Walter, Bonn). Das Wissenschaftsportal vascoda beinhaltet verschiedene Fachportale, und es kann entweder interdisziplinär oder fachspezifisch gesucht werden. Durch die verschiedenen Informationsangebote, die in einem Fachportal vorhanden sind und die in dem Wissenschaftsportal vascoda zusammengefasst sind, entsteht semantische Heterogenität. Oberstes Ziel ist somit die Heterogenitätsbehandlung. Die Erstellung von Crosskonkordanzen (zwischen Indexierungssprachen innerhalb eines Fachgebiets und zwischen Indexierungssprachen unterschiedlicher Fachgebiete) und dem sogenannten Heterogenitätsservice (Term-Umschlüsselungs-Dienst) wurden anhand dieses Wissenschaftsportals vorgestellt. "Crosskonkordanzen sind gerichtete, relevanzbewertete Relationen zwischen Termen zweier Thesauri, Klassifikationen oder auch anderer kontrollierter Vokabulare." Im Heterogenitätsservice soll die Suchanfrage so transformiert werden, dass sie alle relevanten Dokumente in den verschiedenen Datenbanken erreicht. Bei der Evaluierung der Crosskonkordanzen stellt sich die Frage der Zielgenauigkeit der Relationen, sowie die Frage nach der Relevanz der durch die Crosskonkordanz zusätzlich gefundenen Treffer. Drei Schritte der Evaluation werden durchgeführt: Zum einen mit natürlicher Sprache in der Freitextsuche, dann übersetzt in Deskriptoren in der Schlagwortsuche und zuletzt mit Deskriptoren in der Schlagwortsuche mit Einsatz der Crosskonkordanzen. Im Laufe des Sommers werden erste Ergebnisse der Evaluation der Crosskonkordanzen erwartet.

    Der vollständige Titel von Teil 2 lautet "Information and documentation - Thesauri and interoperability with other vocabularies - Teil 2: Interoperability with other vocabularies". Wichtige Themen, die der Standard behandelt, sind Strukturmodelle für das Mapping, Richtlinien für Mappingtypen und der Umgang mit Präkombination, die besonders bei Klassifikationen, Taxonomien und Schlagwortsystemen vorkommt. Das primäre Augenmerk von ISO 25964 gilt den Thesauri, und mit Ausnahme von Terminologien existieren keine vergleichbaren Standards für die anderen Vokabulartypen. Statt zu versuchen, diese normativ darzustellen, behandelt Teil 2 ausschließlich die Interoperabilität zwischen ihnen und den Thesauri. Die Kapitel für die einzelnen Vokabulartypen decken jeweils folgende Sachverhalte ab: - Schlüsseleigenschaften des Vokabulars (deskriptiv, nicht normativ) - Semantische Komponenten/Beziehungen (deskriptiv, nicht normativ) Sofern anwendbar, Empfehlungen für das Mapping zwischen Vokabular und Thesaurus (normativ).
