    Abstract
    Das Themengebiet der Arbeit behandelt Visualisierungen von typisierten Links in Linked Data. Die wissenschaftlichen Gebiete, die im Allgemeinen den Inhalt des Beitrags abgrenzen, sind das Semantic Web, das Web of Data und Informationsvisualisierung. Das Semantic Web, das von Tim Berners Lee 2001 erfunden wurde, stellt eine Erweiterung zum World Wide Web (Web 2.0) dar. Aktuelle Forschungen beziehen sich auf die Verknüpfbarkeit von Informationen im World Wide Web. Um es zu ermöglichen, solche Verbindungen wahrnehmen und verarbeiten zu können sind Visualisierungen die wichtigsten Anforderungen als Hauptteil der Datenverarbeitung. Im Zusammenhang mit dem Sematic Web werden Repräsentationen von zusammenhängenden Informationen anhand von Graphen gehandhabt. Der Grund des Entstehens dieser Arbeit ist in erster Linie die Beschreibung der Gestaltung von Linked Data-Visualisierungskonzepten, deren Prinzipien im Rahmen einer theoretischen Annäherung eingeführt werden. Anhand des Kontexts führt eine schrittweise Erweiterung der Informationen mit dem Ziel, praktische Richtlinien anzubieten, zur Vernetzung dieser ausgearbeiteten Gestaltungsrichtlinien. Indem die Entwürfe zweier alternativer Visualisierungen einer standardisierten Webapplikation beschrieben werden, die Linked Data als Netzwerk visualisiert, konnte ein Test durchgeführt werden, der deren Kompatibilität zum Inhalt hatte. Der praktische Teil behandelt daher die Designphase, die Resultate, und zukünftige Anforderungen des Projektes, die durch die Testung ausgearbeitet wurden.

    Abstract
    Die Wissenschaft befindet sich in einer Auffindbarkeitskrise. Obwohl durch die Open Access-Bewegung Forschungsergebnisse besser zugänglich geworden sind, wird ein signifikanter Teil der Outputs nicht nachgenutzt. Einen großen Anteil an der Krise haben die Tools, die für die Literatursuche verwendet werden. Angesichts von drei Millionen Veröffentlichungen pro Jahr sind klassische Ansätze, wie etwa listenbasierte Suchmaschinen, nicht mehr ausreichend. Open Knowledge Maps hat es sich zum Ziel gesetzt, die Auffindbarkeit wissenschaftlichen Wissens zu verbessern. Dafür betreibt die gemeinnützige Organisation aus Österreich die weltweit größte visuelle Suchmaschine für Forschung. Das Grundprinzip besteht darin, Wissenslandkarten für die Literatursuche zu nutzen. Diese geben einen Überblick über ein Forschungsfeld und ermöglichen so einen schnelleren Einstieg in die Literatur. Open Knowledge Maps basiert auf den Prinzipien von Open Science: Inhalte, Daten und Software werden unter einer freien Lizenz veröffentlicht. Dadurch entsteht eine offene, wiederverwendbare Infrastruktur; Lock-In-Effekte, wie sie bei proprietären Systemen auftreten, werden vermieden. Open Knowledge Maps arbeitet seit Beginn eng mit Bibliotheken und BibliothekarInnen als ExpertInnen für Wissensorganisation und -verwaltung zusammen. Im Rahmen eines konsortialen Fördermodells werden Bibliotheken nun eingeladen, das System stärker mitzugestalten - unter anderem bei wichtigen Zukunftsthemen wie der besseren Auffindbarkeit von Datensätzen.

    Abstract
    Using Google Earth, Google Maps, and/or network visualization programs such as Pajek, one can overlay the network of relations among addresses in scientific publications onto the geographic map. The authors discuss the pros and cons of various options, and provide software (freeware) for bridging existing gaps between the Science Citation Indices (Thomson Reuters) and Scopus (Elsevier), on the one hand, and these various visualization tools on the other. At the level of city names, the global map can be drawn reliably on the basis of the available address information. At the level of the names of organizations and institutes, there are problems of unification both in the ISI databases and with Scopus. Pajek enables a combination of visualization and statistical analysis, whereas the Google Maps and its derivatives provide superior tools on the Internet.

    Abstract
    Die Schlagwortnormdatei (SWD) stellt als kooperativ erstelltes, kontrolliertes Vokabular ein aus dem deutschsprachigen Raum nicht mehr wegzudenkendes Mittel zur Verschlagwortung von Medien dar. Die SWD dient primär der Vereinheitlichung der Verschlagwortung. Darüber hinaus sind in der Struktur der SWD Relationen zwischen Schlagwörtern definiert, die eine gut vorbereitete Suche stark erleichtern können. Beispiel für solche Relationen sind die Unterbegriff-/Oberbegriffrelationen (Hyponym/Hyperonym) oder die Relation der Ähnlichkeit von Begriffen. Diese Arbeit unternimmt den Versuch, durch die Erstellung eines Such- und Visualisierungstools den Umgang mit der SWD zu erleichtern. Im Fokus der Arbeit steht dabei zum einen die Aufgabe des Fachreferenten, ein Medium geeignet zu verschlagworten. Diese Aufgabe soll durch die Optimierung der technischen Suchmöglichkeiten mit Hilfe von Schlagwörtern geschehen, z.B. durch die Suche mit Hilfe Regulärer Ausdrücke oder durch die Suche entlang der hierarchischen Relationen. Zum anderen sind die beschriebenen Relationen innerhalb der SWD oft unsauber spezifiziert, was ein negativer Seiteneffekt der interdisziplinären und kooperativen Erstellung der SWD ist. Es wird gezeigt, dass durch geeignete Visualisierung viele Fehler schnell auffindbar und korrigierbar sind, was die Aufgabe der Datenpflege um ein Vielfaches vereinfacht. Diese Veröffentlichung geht zurück auf eine Master-Arbeit im postgradualen Fernstudiengang Master of Arts (Library and Information Science) an der Humboldt-Universität zu Berlin.

    Abstract
    Methoden und Techniken der Informationsvisualisierung werden seit ungefähr zwanzig Jahren im Bereich der Informationssuche eingesetzt. In dieser Literaturstudie werden ausgewählte Visualisierungsanwendungen der letzten Jahre vorgestellt. Sie betreffen zum einen den Retrievalprozess, das Boolesche Retrieval, die facettierte Suche, Dokumentbeziehungen, die Zufallssuche und Ergebnisanzeige, zum anderen spezielle Anwendungen wie die kartenbasierte und adaptive Visualisierung, Zitationsnetzwerke und Wissensordnungen. Die Einsatzszenarien für Applikationen der Informationsvisualisierung sind vielfältig. Sie reichen von mobilen kleinformatigen Anwendungen bis zu großformatigen Darstellungen auf hochauflösenden Bildschirmen, von integrativen Arbeitsplätzen für den einzelnen Nutzer bis zur Nutzung interaktiver Oberflächen für das kollaborative Retrieval. Das Konzept der Blended Library wird vorgestellt. Die Übertragbarkeit von Visualisierungsanwendungen auf Bibliothekskataloge wird im Hinblick auf die Nutzung des Kataloginputs und des Angebots an Sucheinstiegen geprüft. Perspektivische Überlegungen zu zukünftigen Entwicklungsschritten von Bibliothekskatalogen sowie zum Einfluss von Visualisierungsanwendungen auf die Informationspraxis werden angestellt.

    Abstract
    Die Bayerische Staatsbibliothek (BSB) zählt mit ihrem Bestand von knapp 11 Mio. Bänden zu den bedeutendsten Universalbibliotheken der Welt. Bereits 1,2 Mio. Werke sind digitalisiert, was die BSB zur größten digitalen Kulturinstitution in Deutschland macht. Dieser digitale Bestand umfasst vorwiegend urheberrechtsfreie Werke vom 8. bis ins 20. Jahrhundert, von der mittelalterlichen Bibelhandschrift bis zur Boulevardzeitung der 1920er-Jahre. Diese Vielfalt des zu digitalisierenden schriftlichen Kulturerbes und das hohe Tempo der Massendigitalisierung in den letzten Jahren haben ihren Preis - die inhaltliche Erschließung der Werke hinkt hinterher, insbesondere bei Werken, die nicht mittels Optical Character Recognition-Verfahren (OCR) automatisiert maschinenlesbar transformiert und zugänglich gemacht werden können. Dies gilt insbesondere für mittelalterliche Handschriften, Alte Druck- und Spezialbestände. Deshalb blieb auch der reichhaltige, in diesen Werken verborgene Bildbestand für den Nutzer weitestgehend verborgen und konnte lediglich durch das Durchblättern am Bildschirm entdeckt werden. Dies war Motivation für die Bayerische Staatsbibliothek, gemeinsam mit dem Fraunhofer Heinrich-Hertz-Institut in Berlin ein System zur ähnlichkeitsbasierten Bildsuche aufzubauen, welches sämtliche Bildinhalte aller 1,2 Mio. Digitalisate automatisch identifiziert. Hierbei werden mittels morphologischer Verfahren Bilder aus den Buchseiten extrahiert, die danach aufgrund von Farb- und Kantenmerkmalen klassifiziert werden. Bilder "ohne Informationswert" werden mit Hilfe von Methoden aus dem Bereich des maschinellen Lernens herausgefiltert. Damit konnten aus den digitalisierten Werken der BSB bislang mehr als 43 Mio. einzelne Bilder identifiziert werden, die mittels einer hochperformanten Suchmaschine über eine frei verfügbare Web-Applikation dem Anwender direkt zur Verfügung stehen. Dank der Vielfalt und Reichhaltigkeit der indexierten Bestände spricht dieses Angebot nicht nur Historiker und Buchwissenschaftler an, sondern Interessierte aus den unterschiedlichsten Fachrichtungen. Die Ähnlichkeitssuche stellt dabei unbekannte, ungewöhnliche und oftmals überraschende Bezüge zwischen unterschiedlichsten Werken her.

    Abstract
    Datenvisualisierungen sind ein wichtiges Werkzeug, um Inhalte und Muster in Datensätzen zu erkennen und ermöglichen so auch Laien den Zugang zu der Information, die in Datensätzen steckt. Data Visualization Literacy ist die Kompetenz, Datenvisualisierungen zu lesen, zu verstehen, zu hinterfragen und herzustellen. Data Visulaization Literacy ist daher eine wichtige Kompetenz der Informationsgesellschaft. Im Auftrag des Bundesrates hat das Bundesamt für Kommunikation BAKOM die Strategie "Digitale Schweiz" entwickelt. Die Strategie zeigt auf, wie die fortschreitende Digitalisierung genutzt und die Schweiz zu einer Informationsgesellschaft entwickelt werden soll. In der vorliegenden Arbeit wird untersucht, inwiefern die Strategie "Digitale Schweiz" die Förderung von Data Visualization Literacy in der Bevölkerung unterstützt. Dazu werden die Kompetenzen der Data Visualization Literacy ermittelt, Kompetenzstellen innerhalb des Bildungssystems benannt und die Massnahmen der Strategie in Bezug auf Data Visualization Literacy überprüft.

    Abstract
    Icon system could represent an efficient solution for collective iconic categorization of knowledge by providing graphical interpretation. Their pictorial characters assist visualizing the structure of text to become more understandable beyond vocabulary obstacle. In this paper we are proposing a Knowledge Engineering (KM) based iconic representation approach. We assume that these systematic icons improve collective knowledge management. Meanwhile, text (constructed under our knowledge management model - Hypertopic) helps to reduce the diversity of graphical understanding belonging to different users. This "position paper" also prepares to demonstrate our hypothesis by an "iconic social tagging" experiment which is to be accomplished in 2011 with UTT students. We describe the "socio semantic web" information portal involved in this project, and a part of the icons already designed for this experiment in Sustainability field. We have reviewed existing theoretical works on icons from various origins, which can be used to lay the foundation of robust "icons systems".

    Abstract
    Zielsetzung - Aufgrund der rasch wachsenden Anzahl an Publikationen zur Informationskompetenz ergibt sich eine zunehmende Notwendigkeit von Überblicksarbeiten. Dieser Betrag hat das Ziel, mittels Science Mapping einen Überblick über die wissenschaftliche Literatur zu schaffen. Forschungsmethoden - Unter Verwendung von BibExcel und VOSviewer wurden 1589 wissenschaftliche Artikel analysiert und drei verschiedene Visualisierungen erstellt. Ergebnisse - Es gibt ein relativ großes internationales Autorennetzwerk, in welchem die meisten Hauptakteure miteinander in Verbindung stehen. Die wichtigsten Schwerpunkte sind: Vermittlung von Informationskompetenz im Hochschulbereich, Prozessmodelle zum Informationssuchverhalten, Phänomenographie und Informationskompetenz im beruflichen Umfeld. Schlussfolgerungen - Viele der Schwerpunkte wurden schon vereinzelt in Review-Artikeln genannt, aber noch nie via Science Mapping zusammen visualisiert. Somit ermöglicht diese Arbeit erstmalig ein »big picture« der Produktionslandschaft. Künftige Arbeiten könnten die Literatur mit anderen Science Mapping Tools bzw. Visualisierungstechniken untersuchen.

    Abstract
    Ausgewählte Visualisierungsanwendungen der jüngeren Vergangenheit, die den Retrievalprozess betreffen, werden vorgestellt. Die Einsatzszenarien reichen von mobilen kleinformatigen Anwendungen bis zu großformatigen Darstellungen auf hochauflösenden Bildschirmen, von integrativen Arbeitsplätzen für den einzelnen Nutzer bis zur Nutzung interaktiver Oberflächen für das kollaborative Retrieval. Das Konzept der Blended Library wird erläutert. Perspektivische Überlegungen zu zukünftigen Entwicklungsschritten von Bibliothekskatalogen sowie zum Einfluss von Visualisierungsanwendungen auf die Informationspraxis werden angestellt.

    Abstract
    Dieser Artikel beschäftigt sich mit den Möglichkeiten der Informationsaufbereitung durch computergenerierte dreidimensionale Elemente. Visualisierungen durch 3DGrafiken und Animationen können im Vergleich zum Informationsgehalt andersartiger Darstellungen einen kommunikativen Mehrwert aufweisen, der den höheren Aufwand der Erzeugung rechtfertigt. Es wird die Frage aufgeworfen, in welchen Forschungsgebieten der Informationswissenschaft und Medieninformatik der Einsatz von räumlichen Repräsentationen angebracht ist und inwieweit sich die Fokussierung auf eine Informationsübermittlung durch eine virtuelle 3D-Umgebung mit den gesteigerten Anforderungen an das Kommunikationssystem in Einklang bringen lässt. Durch die menschliche Ausrichtung auf möglichst natürliche und realistische Erscheinungen bei der Informationsaufnahme ist die Verwendung der dritten Dimension im Kommunikationsprozess ausgenommen hilfreich, es bedarf zuvor allerdings einer Konzeption geeigneter Einsatzprinzipien, die der großflächigen Anwendung im Bedarfsfall gerecht werden.

    Abstract
    The goal of Open Knowledge Maps is to create a visual interface to the world's scientific knowledge. The base for this visual interface consists of so-called knowledge maps, which enable the exploration of existing knowledge and the discovery of new knowledge. Our open source knowledge mapping software applies a mixture of summarization techniques and similarity measures on article metadata, which are iteratively chained together. After processing, the representation is saved in a database for use in a web visualization. In the future, we want to create a space for collective knowledge mapping that brings together individuals and communities involved in exploration and discovery. We want to enable people to guide each other in their discovery by collaboratively annotating and modifying the automatically created maps.

    Abstract
    Studies on the state and structure of digital knowledge concerning science generally relate to macro and meso scales. Supported by visualizations, these studies can deliver knowledge about emerging scientific fields or collaboration between countries, scientific centers, or groups of researchers. Analyses of individual activities or single scientific career paths are rarely presented and discussed. The authors decided to fill this gap and developed a web application for visualizing the scientific output of particular researchers. This free software based on bibliographic data from local databases, provides six layouts for analysis. Researchers can see the dynamic characteristics of their own writing activity, the time and place of publication, and the thematic scope of research problems. They can also identify cooperation networks, and consequently, study the dependencies and regularities in their own scientific activity. The current article presents the results of a study of the application's usability and functionality as well as attempts to define different user groups. A survey about the interface was sent to select researchers employed at Nicolaus Copernicus University. The results were used to answer the question as to whether such a specialized visualization tool can significantly augment the individual information space of the contemporary researcher.

    Abstract
    Representation in Scientific Practice, published by the MIT Press in 1990, helped coalesce a long-standing interest in scientific visualization among historians, philosophers, and sociologists of science and remains a touchstone for current investigations in science and technology studies. This volume revisits the topic, taking into account both the changing conceptual landscape of STS and the emergence of new imaging technologies in scientific practice. It offers cutting-edge research on a broad array of fields that study information as well as short reflections on the evolution of the field by leading scholars, including some of the contributors to the 1990 volume. The essays consider the ways in which viewing experiences are crafted in the digital era; the embodied nature of work with digital technologies; the constitutive role of materials and technologies -- from chalkboards to brain scans -- in the production of new scientific knowledge; the metaphors and images mobilized by communities of practice; and the status and significance of scientific imagery in professional and popular culture.

    Abstract
    Science mapping aims to build bibliometric maps that describe how specific disciplines, scientific domains, or research fields are conceptually, intellectually, and socially structured. Different techniques and software tools have been proposed to carry out science mapping analysis. The aim of this article is to review, analyze, and compare some of these software tools, taking into account aspects such as the bibliometric techniques available and the different kinds of analysis.
