- 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 Vielzahl der Publikationen zeigt, dass Information Seeking Behaviour (ISB) bzw. Informationssuchverhalten in der informationswissenschaftlichen Forschung als relevantes Thema angesehen wird. ISB versteht sich als Unterkategorie von Information Behaviour (IB) bzw. Informationsverhalten, das jegliches menschliches Verhalten mit Bezug zu Wissen und Information umfasst, also z. B. auch Informationsvermeidung oder passives Informationsverhalten. ISB hingegen wurde anfänglich meist als bewusster Prozess verstanden, um sich aufgrund einer festgestellten Wissenslücke Information zu beschaffen. Information Seeking wird als eine alltägliche Aktivität angesehen, die meist dann auftritt, wenn eine informationell unterbestimmte Handlung durchgeführt werden soll

- Abstract
- Im Mittelpunkt des vorliegenden Beitrags steht das Cross-Language Information Retrieval, das mit seinen sprachübergreifenden Funktionen zur Minderung von Sprachbarrieren bei der Informationssuche beiträgt. Hier sollen insbesondere die Eigennamen untersucht werden. Evaluierungsstudien haben gezeigt, dass ihnen aufgrund ihrer besonderen Eigenschaften eine wichtige Rolle bei der Identifikation von relevanten Dokumenten zukommt. Verfahren für die Optimierung des mehrsprachigen Retrievalprozesses werden angesprochen.

- Abstract
- Das Ziel einer Evaluation ist die Überprüfung, ob bzw. in welchem Ausmaß ein Informationssystem die an das System gestellten Anforderungen erfüllt. Informationssysteme können aus verschiedenen Perspektiven evaluiert werden. Für eine ganzheitliche Evaluation (als Synonym wird auch Evaluierung benutzt), die unterschiedliche Qualitätsaspekte betrachtet (z. B. wie gut ein System relevante Dokumente rankt, wie schnell ein System die Suche durchführt, wie die Ergebnispräsentation gestaltet ist oder wie Suchende durch das System geführt werden) und die Erfüllung mehrerer Anforderungen überprüft, empfiehlt es sich, sowohl eine perspektivische als auch methodische Triangulation (d. h. der Einsatz von mehreren Ansätzen zur Qualitätsüberprüfung) vorzunehmen. Im Information Retrieval (IR) konzentriert sich die Evaluation auf die Qualitätseinschätzung der Suchfunktion eines Information-Retrieval-Systems (IRS), wobei oft zwischen systemzentrierter und nutzerzentrierter Evaluation unterschieden wird. Dieses Kapitel setzt den Fokus auf die systemzentrierte Evaluation, während andere Kapitel dieses Handbuchs andere Evaluationsansätze diskutieren (s. Kapitel C 4 Interaktives Information Retrieval, C 7 Cross-Language Information Retrieval und D 1 Information Behavior).

- Abstract
- Durch die ständig wachsende internationale Vernetzung ist auch bei der Suche nach Information seit langem eine intensive Entwicklung in Richtung Mehrsprachigkeit feststellbar. Diese wird meist von den Systemen und Technologien her betrachtet. Im informationellen Kontext ist auch die Seite der Nutzer*innen hinzuzuziehen, die etwa in Hinblick auf ihre Mehrsprachigkeit sehr unterschiedlich einzuschätzen sind. Kompetenzen in verschiedenen Sprachen sind eher die Regel als reiner Monolingualismus, der heute nur sehr selten vorzufinden ist. Die Nutzer*innen unterscheiden sich in den Niveaus ihrer Sprachkompetenz, die von rudimentärem Sprachverständnis bis hin zu muttersprachlichen Fähigkeiten reichen. Es wird zunehmend zur Gewohnheit und auch zur Notwendigkeit, auf multilinguale Kollektionen zuzugreifen und nach Information nicht nur in der Muttersprache zu suchen. Oft hängt dies auch davon ab, ob in beruflichen oder privaten Umgebungen mit entsprechenden Zielsetzungen gesucht wird. Information bleibt Information, auch wenn verschiedene Sprachen aufeinandertreffen, was z. B. für verschiedene mediale Formen von Informationsobjekten wie z. B. Bilder gilt.

- Abstract
- Der folgende Beitrag ordnet die Informationswissenschaft in den nationalen und internationalen Kanon der Wissenschaftsdisziplinen ein und zeigt deren Besonderheiten und Wurzeln auf. Im Zentrum steht die Informationswissenschaft an der Universität Hildesheim, deren Schwerpunkte sich inhaltlich im Bereic der internationalen Mensch-Maschine-Interaktion und des Cross-Language Information Retrieval ansiedeln. Kurz werden auch neuere Forschungsgebiete und -methoden angesprochen. Der Beitrag schließt mit einem Blick auf zukünftige Entwicklungsperspektiven.

- Abstract
- In diesem Beitrag wird ein adaptives Information-Retrieval-Modell im Kontext Digitaler Bibliotheken vorgestellt, das während des Informationsprozesses lernt, Beziehungen zwischen Repräsentationsformen und Informations-Objekten herzustellen. Die aus großen Evaluierungsstudien abgeleiteten Erkenntnisse, dass Relevance Feedback und Polyrepräsentation echte Mehrwerte darstellen und zu besserer Retrievalqualität führen, dienen dabei als Grundlage. Um eine stärkere Adaption zu leisten, wird das Modell um Strategien erweitert, die Benutzer-, Dokument- und Anfrageeigenschaften einbeziehen. Im Rahmen Digitaler Bibliotheken spielen insbesondere Transformationen unterschiedlich erschlossener Objekte eine wichtige Rolle zur Kompensation semantischer Heterogenität. Auch in diesem Rahmen kann das adaptive Information-Retrieval-Modell eingesetzt werden

- Abstract
- Seit einigen Jahren hat sich in Europa eine Initiative zur Bewertung von Information Retrieval in mehrsprachigen Kontexten etabliert. Das Cross Language Evaluation forum (CLEF) wird von der EU gefördert und kooperiert mit Evaluierungsprojekten in den USA (TREC) und in Japan (NTCIR). Dieser Artikel stellt das CLEF in den Rahmen der anderen internationalen Initiativen. Neue Entwicklungen sowohl bei den Information Retrieval Systemen als auch bei den Evaluierungsmethoden werden aufgezeit. Die hohe Anzahl von Teilnehmern aus Forschungsinstitutionen und der Industrie beweist die steigende Bedeutung des sprachübergreifenden Retrievals
