    Abstract
    Therefore our main research questions are as follows: - Is it possible to discover regular patterns in tag usage and to establish a stable category model? - Does a specific tagging language comparable to internet slang or chatspeak evolve? - How do social tags differ from traditional (author / expert) keywords? - To what degree are social tags taken from or findable in the full text of the tagged resource? - Do tags in a research literature context go beyond simple content description (e.g. tags indicating time or task-related information, cf. Kipp et al. 2006)?

    Abstract
    In the introduction for this special issue we briefly review the development of social software, contrasting it with earlier group-based computer applications like groupware and computer- supported cooperative work. The contributions selected span a wide range starting from reflections on informality as a key property of social software. Case studies give details on using wikis for knowledge management and the influence of choosing a specific wiki engine. The transformation problem for non-digital information services is discussed in the context of a large research institute. More recent types of social systems and their potential use for knowledge management are discussed for microblogs as well as semantic wiki systems. Finally, an overview study gives information on the intensity of social software usage for customer communications in large European companies.

    Abstract
    In this paper we present a multimodal design concept for a materials information system interface. The project WING-IIR combines both form-oriented and natural language database in a GUI-based environment, giving the user a choice of query modes. Our design is embedded in a tool-based, object oriented structure which allows for adequate interpretation and usability for both, novice and expert users. Implementing context-sensitivity and transparency between query modalities and different levels of data granularity further help in solving difficult materials problems. In addition a number of different Intelligent Information Retrieval (IIR) modules complement the basic database interface: a stereotype-based user model reduces interface complexity by adapting to the users' actual interests; the WING-GRAPH component allows for graphical retrieval of materials curves, i.e. users may manipulate graphical data representations in order to query the database and a fuzzy-WING component is proposed for modelling vagueness in natural language queries as well as for vague interpretation of seemingly exact queries

    Abstract
    Die meisten Web-Auftritte der Hosts waren bisher für den Retrieval-Laien gedacht. Im Hintergrund steht dabei das Ziel: mehr Nutzung durch einfacheres Retrieval. Dieser Ansatz steht aber im Konflikt mit der wachsenden Datenmenge und Dokumentgröße, die eigentlich ein immer ausgefeilteres Retrieval verlangen. Häufig wird von Information Professionals die Kritik geäußert, dass die Webanwendungen einen Verlust an Relevanz bringen. Wie weit der Nutzer tatsächlich einen Kompromiss zwischen Relevanz und Vollständigkeit eingehen muss, soll in diesem Beitrag anhand verschiedener Host-Rechner quantifiziert werden

    Abstract
    Das vorliegende Buch befaßt sich mit der theoretischen Begründung, Gestaltung und empirischen Bewertung eines Datenbankzugangs durch graphisches Retrieval. Der Autor stellt das Informationssystem Wing-Graph vor, das am Beispiel Werkstoffdaten die Veränderung von Liniendiagrammen durch graphische Aktionen in der benutzeroberfläche zur Recherche nach numerischer Information erlaubt. Darunter ist eine graphische Recherchesprache zu verstehen, mit der man visuelles Denken direkt für die Suche nutzen kann. Der Autor entwickelt auf der Basis kognitionspsychologischer Erkenntnisse über Wahrnehmung und Interpretation von Informationsgraphiken ein Modell des graphischen Retrieval, in dem 3 wichtige Aspekte der Interaktion mit graphischer Information vereinigt sind: die visuelle Vorstellungsfähigkeit, der Handlungsaspekt der Mensch-Maschine-Interaktion und die Systemfunktionalität einer graphischen Datenbankschnittstelle. Im Vergleich mit traditionellen Abfragesprachen stehen in Wing-Graph einfache, aber leistungsfähige graphische Operationen zur Verfügung, die das visuelle Denken des Benutzers operationalisieren. Die Generalisierbarkeit des Ansatzes für andere Domänen wird untersucht und in exemplarischer Weise an Wirtschaftsdaten überprüft

    Abstract
    We describe an infrastructure for the collection and management of large amounts of text, and discuss the possibility of information extraction and visualisation from text corpora with statistical methods. The paper gives an overview of processing steps, the contents of our text databases as well as different query facilities. Our focus is on the extraction and visualisation of collocations and their usage for aiding web searches

    Abstract
    Der 'Ort ohne Raum' ist eine Galerie im WWW, die versucht, die Nutzungsstruktur des WWW mit meist (hyper-)textueller Information zu interaktiven Anwendungen zu erweitern, in die der Anwender selbst eingreifen kann. Das Ziel ist nicht eine einfach Reproduktion des Konzeptes einer Galerie in einem anderen Medium, sondern die Spezifik des Mediums soll den Betrachter zu grundsätzlich anderen und erweiterten Interaktions-, Manipulations- und Navigationsmöglichkeiten führen. Der 'Ort ohne Raum' entsteht seit 1995 als Kooperationsprojekt zwischen den Fachbereichen Medienkunst der Hochschule für Grafik und Buchkunst in Leipzig und der Abteilung für Automatische Sprachverarbeitung am Institut für Informatik der Universität Leipzig
