- 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
- The application of classification schemes and thesauri to improve online information retrieval can be traced back to the beginnings of online searching itself, but the true potential for using knowledge structures in the user interface has yet to be realized. View-based searching seeks to exploit the classified arrangements in thesauri and existing classification schemes to improve the performance of such systems. HIBROWSE for EMBASE is a system which demonstrates the power of applying an approach to information retrieval which is strongly related to faceted classification. It does this by employing a point a click user interface with mutually constraining views utilising knowledge structure hierarchies for both query specification and the presentation of results. The relevance of this approach to library OPACs is discussed in the context of the digital library, concluding that out legacy of research in classification and indexing is more relevant than ever in the design of systems to cope with the problems of information access

- Abstract
- This paper discusses constraints in knowledge organisation for information retrieval introduced by the difficulty of separating logical views of data, information, concepts and their relationships, from the physical means by which we seek to implement retrieval systems. A parallel is drawn between the move from enumerated to faceted classification and the emergence of relational database management systems to replace those adopting a hierarchical structure. This parallel suggests a convergence of ideas which have been, to a large extent, developed independently. The role of post-coordinated retrieval systems and thesauri is then examined before an interface design (HIBROWSE - a High resolution Interface for BROWsing and SEarching databases), is described which brings together the principles of faceted classification and increases the bandwidth of interaction through view-based searching.

- Abstract
- Browse searching of online catalogs and electronic indexes is a popular means of retrieving information, but some subject heading lists are so extensive that browsing them can be difficult and time-consuming. This resaerch tested one way of presenting a browse interface to reduce the amount of scanning of subject headings required. It found that a hierarchical presentation of headings reduced the amount of scanning required by more than 50% without any reduction in the effectiveness of the search. Better browsable displays of this sort can improve the efficiency of searching but appear not to alter effectivenenss

- Abstract
- Compares and contrasts online searching on DataStar using the 'classic' command language, with access via the more recent Web interface (DataStar Web). The search functionality of the 2 interfaces is not identical, although both use the same retrieval software and access the same databases. Many of the differences affect retrieval effectiveness and may trip up novice and experienced searchers alike

- Abstract
- Selection of search terms in an online search environment can be facilitated by the visual display of a knowledge map showing the various concepts and their links. This paper reports an a preliminary research aimed at designing a prototype knowledge map using DDC and its visual display. The prototype knowledge map created using the Protégé and TGViz freeware has been demonstrated, and further areas of research in this field are discussed.

- 1. Introduction Web search engines and digital libraries usually expect the users to use search terms that most accurately represent their information needs. Finding the most appropriate search terms to represent an information need is an age old problem in information retrieval. Keyword or phrase search may produce good search results as long as the search terms or phrase(s) match those used by the authors and have been chosen for indexing by the concerned information retrieval system. Since this does not always happen, a large number of false drops are produced by information retrieval systems. The retrieval results become worse in very large systems that deal with millions of records, such as the Web search engines and digital libraries. Vocabulary control tools are used to improve the performance of text retrieval systems. Thesauri, the most common type of vocabulary control tool used in information retrieval, appeared in the late fifties, designed for use with the emerging post-coordinate indexing systems of that time. They are used to exert terminology control in indexing, and to aid in searching by allowing the searcher to select appropriate search terms. A large volume of literature exists describing the design features, and experiments with the use, of thesauri in various types of information retrieval systems (see for example, Furnas et.al., 1987; Bates, 1986, 1998; Milstead, 1997, and Shiri et al., 2002).

- Abstract
- Reports on the design of a GUI for the Okapi 'best match' retrieval system developed at the Centre for Interactive Systems Research, City University, UK, for online library catalogues. The X-Windows interface includes an interactive query expansion (IQE) facilty which involves the user in the selection of query terms to reformulate a search. Presents the design rationale, based on a game board metaphor, and describes the features of each of the stages of the search interaction. Reports on the early operational field trial and discusses relevant evaluation issues and objectives

- Abstract
- Ausgehend von einer Diskussion der Gestaltungskonzeptionen und der Leistungsfähigkeit heutiger Volltext-Retrieval-Systeme wird ein Überblick über den Leistungsumfang des für die Aufbereitung und Präsentation von Textinformation zuständigen Systems TWRM-TOPOGRAPHIC gegeben. TWRM-TOPOGRAPHIC ist Teil eines neuartigen Informationssystems, das sich auf inhaltsorientierte Repräsentation von Volltexten stützt. Die beiden wesentlichsten Leistungsmerkmale von TWRM-TOPOGRAPHIC sind die graphische Retrievaldialogführung und die flexible, situationsgerechte Aufbereitung und Präsentation von Textwissen: Die Dialogführung erlaubt dem Benutzer die direkte Navigation in den auf dem Bildschirm graphisch dargestellten Wissensstrukturen, die Selektion dargestellter Objekte zur Formulierung einer Query sowie das Wechseln des Abstraktionsniveaus der dargestellten Textinformation. Die Aufbereitung und die Präsentation von Textwissen sind kognitiv-ergonomisch begründet und berücksichtigen sowohl die begrenzte Aufnahmekapazität der Benutzer als auch die Bedeutung der zeitlichen Anordnung von Informationseinheiten für die Wahmehmungs- und Gedächtnisleistung der Rezipienten. Textwissen wird in unterschiedlichen Abstraktionsstufen präsentiert: von einer sehr generischen Ebene über Wissensgraphen, automatisch generierten Abstracts bis zur diskursiven Form der Textpassage. Die Generierungskomponente des Systems leistet einen Beitrag zum situationsgerechten Systemverhalten dadurch, daß sie aus semantischen Text-Repräsentationsstrukturen unter Berücksichtigung textueller Wohlgeformtheitsbedingungen benutzerangepaßte Abstracts mit unterschiedlichem Themenschwerpunkt und variabler Ausführlichkeit produziert. Die Erprobung verschiedener LayoutVerfahren im Projekt TWRM-TOPOGRAPHIC wird durch ein flexibles, objektorientiert spezifiziertes User-Interface-Mangagement-System (UIMS) unterstützt, dessen Objektklassen und deren Interaktionsmöglichkeiten vorgestellt werden. Die Darstellung des Systems wird mit einem ausführlichen Dialogbeispiel abgeschlossen, das die Funktion des Interface und die Wirkung der drei zentralen Operatoren (Select, Zoom und Browse) im Retrievaldialog illustriert.

- Abstract
- This paper examines issues relating to the use of the Dewey Decimal Classification (DDC) in a future development of view-based searching to Online Public Access Catalogues (OPAC). View-based searching systems, exercising the principles of fully faceted classification techniques for both bibliographic and corporate database retrieval applications, are now being applied to utilise Dewey concept hierarchies in a University OPAC. Issues of efficiency and effectiveness in the evolving organisation and classification of information within libraries are examined to explain why fully faceted classification schemes have yet to realise their full potential in libraries. The key to their application in OPACs lies in the use of faceted classification as pre-coordinated indexing and abandoning the single dimension relative ordering of books on shelves. The need to maintain a single relative physical position on a bookshelf is the major source of complexity in classification. Extensive latent benefits will be realised when systematic subject arrangements, providing alternative views onto OPACs, are coupled to view-based browser and search techniques. Time and effort will be saved, and effectiveness increased, as rapid access is provided to the most appropriate information to satisfy the needs of the user. A future for Dewey Classification divorced from its decimal notation is anticipated

- Abstract
- Die Schaffung eines natürlichsprachlichen Interfaces (NLI), (das einem Nutzer die Formulierung von Anfragen an Informationsanbieter in seiner Muttersprache erlaubt, stellt eine der interessantesten Herausforderungen im Bereich des Information-Retrieval und der Verarbeitung natürlicher Sprache dar. Dieser Beitrag beschreibt Methoden zur Obersetzung natürlichsprachlicher Anfragen in Ausdrücke formaler Retrievalsprachen sowohl für Informationsressourcen im Internet als auch für lokale Datenbanken. Die vorgestellten Methoden sind Teil das Informationsrecherchesystems LINAS, das an der Fernuniversität Hagen entwickelt wurde, um Nutzern einen natürlichsprachlichen Zugang zu lokalen und zu im Internet verteilten wissenschaftlichen und technischen Informationen anzubieten. Das LINAS-System unterscheidet sich von anderen Systemen und natürlichsprachlichen Interfaces (vgl. OSIRIS) oder die früheren Systeme INTELLECT, Q&A durch die explizite Einbeziehung von Hintergrundwissen und speziellen Dialogmodellen in den Übersetzungsprozeß. Darüber hinaus ist das System auf ein vollständiges Verstehen des natürlichsprachlichen Textes ausgerichtet, während andere Systeme typischerweise nur nach Stichworten oder bestimmten grammatikalischen Mustern in der Eingabe suchen. Ein besonderer Schwerpunkt von LINAS liegt in der Repräsentation und Auswertung der semantischen Relationen zwischen den in der Nutzeranfrage gegebenen Konzepten

- Abstract
- Die moderne Informationstechnik bietet die vielfältigsten Möglichkeiten, Publikationen, ob fürs Internet oder für die Druckausgabe, farbig zu gestalten. Dadurch, dass die Handhabung von Bildbearbeitungs- und Grafik-Software im Bereich Desktop Publishing immer einfacher wird, wird sie schon lange nicht mehr ausschließlich von professionellen Designern, sondern von Fachleuten der verschiedensten Berufsgruppen benutzt. Die allerdings haben in den seltensten Fällen gelernt, wie man mit Farben richtig umgeht. Ihnen wird hier eine Einführung in die Farbentheorie geboten, verbunden mit Grundlagen für die praktische Farbgestaltung

- Abstract
- Bei der Frage nach der Ästhetik in der Ergonomie hat sich in den letzten Jahren ein Wandel vollzogen. Noch in den 1990er Jahren missachteten Ergonomen ästhetische Faktoren in der Gestaltung von Benutzungsschnittstellen weitgehend. Inzwischen hat sich allerdings das gegenseitige Interesse von Ergonomen und Designern verstärkt, so dass sich Herausgeber und Autor entschlossen, mit dem vorliegenden Band eine erweiterte und aktualisierte Ausgabe der vergriffenen ersten Auflage vorzustellen. Einige Teile der Erstauflage sind gestrafft, andere aktualisiert. Ferner wurden Teile hinzugefügt, die den aktuellen Stand der Thematik in Theorie und Praxis widerspiegeln. Der nun vorliegende Forschungsbericht enthält über 50 neue Textseiten, 39 neue Abbildungen und fast 90 neu eingearbeitete Referenzen. Weitere Informationen zum Inhalt von Buch und CD-ROM sowie eine tabellarische Gbersicht über die Veränderungen gegenüber der ersten Auflage finden sich im Internet unter www.gesis.org/Information/Forschungsuebersichten/Forschungsberichte/Visualisierung2.htm, Informationen zur (vergriffenen) ersten Auflage unter www.gesis.org/Information/Forschungsuebersichten/Forschungsberichte/Visualisierung.htm.
