    Abstract
    Zweidimensionale Karten dienen im Information Retrieval (IR) immer häufiger der Visualisierung von Dokumentbeständen. Über die Qualität der verschiedenen Methoden zur Erzeugung dieser Karten ist wenig bekannt. In diesem Artikel werden nach einem Überblick über Stand der Forschung und Technik zu Visualisierungen und ihrer Bewertung zwei Verfahren hinsichtlich ihrer Unterschiede verglichen. Die Evaluierung basiert auf der Perspektive des Benutzers beim Browsing in einer Karte. Das Experiment zeigt, dass die Methoden sowohl bei großen als auch bei kleinen Dokumentenmengen zu sehr unterschiedlichen Karten führen und zwischen den Karten keine Korrelation besteht. Das Ergebnis der Untersuchung ist in zweifacher Hinsicht interpretierbar. zum einen kann nicht davon ausgegangen werden, dass sich ein spezielles Verfahren der Dimensionsreduktion eindeutig anbietet, es muss also auf den speziellen Anwendungsfall hin überprüft werden, welches Verfahren anzuwenden ist. Zum anderen scheint aber auch kein Verfahren zu vollkommen unbrauchbaren Ergebnissen zu führen, so dass davon ausgegangen werden kann, dass die einzelnen Verfahren einander ergänzend unterschiedliche Aspekte des Dokumentbestandes beleuchten. Hierzu sollten weitere Tests folgen.

    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.
