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

Describes SIFT (Search in Free Text) an information retrieval system originally developed for administering governmental documents in Norway but which is now being applied alsewhere. SIFT handles structured information well. A library system, SIFT-BIBL, is now available. SIFT's retrieval engine and search facilities are powerful. Its user interface is limited but being imporved. An application programmer interface has been released which will allow programmers to develop their own interface. A Windows-based- client-server version is now being beta tested

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

A new search paradigm, in which the primary user activity is the guided exploration of a complex information space rather than the retrieval of items based on precise specifications, is proposed. The author claims that this paradigm is the norm in most practical applications, and that solutions based on traditional search methods are not effective in this context. He then presents a solution based on dynamic taxonomies, a knowledge management model that effectively guides users to reach their goal while giving them total freedom in exploring the information base. Applications, benefits, and current research are discussed.

Abstract

The authors describe user interface tools based on search histories to support legal information seekers. The design of the tools was informed by the results of a user study (Komlodi, 2002a) that examined the use of human memory, external memory aids, and search histories in legal information seeking and derived interface design recommendations for information storage and retrieval systems. The data collected were analyzed to identify potential task areas where search histories can support information seeking and use. The results show that many information-seeking tasks can take advantage of automatically and manually recorded history information. These findings encouraged the design of user interface tools building on search history information: direct search history displays, history-enabled scratchpad facilities, and organized results collection tools.

Abstract

Wie geht der Mensch mit komplexen Computersystemen um? Wovon hängt die Effizienz der Interaktion ab? Ausgehend von Erkenntnissen der kognitiven Psychologie charakterisiert das Buch den Gestaltungsspielraum beim Entwurf interaktiver Systeme und erläutert die Anwendung verschiedener Interaktionstechniken und -stile. - Zunächst werden grundlegende Konzepte der Interaktion anhand von Beispielen aus dem alltäglichen Leben, wie Auto und Telefon, behandelt. Aus der nachfolgenden Problemanalyse werden Entwurfsprinzipien abgeleitet und in einem technischen Teil allgemeine Konzepte der Arbeitsweise von Fenstersystemen und deren Bestandteile detailliert erläutert: Fenster, Icons, Menüs, Zeigegeräte. Es wird argumentiert, daß der Prozeß der Entwicklung interaktiver Systeme stark iterativ ist und Zyklen aus Analyse, Entwurf und Testverfahren enthält. Konkrete Methoden für diese Schritte werden erläutert, wobei Testverfahren, Methoden zur Spezifikation interaktiver Systeme und Werkzeuge, die die Entwicklung unterstützen, einen breiten Raum einnehmen. Umfassend werden im abschließenden Teil moderne Anwendungsfelder, wie die Interaktion mit sehr großen Datenmengen (die Visualisierung großer Informationsräume), die Interaktion im WWW und die Interaktion mit 3D-Daten (die Entwicklung von 3D-Widgets), behandelt. Lehrbuch mit hohem Praxisbezug: Fallbeispiele aus der industriellen Praxis mit umsetzbaren Hinweisen und Methoden zur Entwicklung und Evaluierung interaktiver Systeme zugeschnitten auf die konstruktiven Aspekte der Interaktion Mensch - Computer mit hochaktuellen Themen wie die Entwicklung von 3D-Widgets und die Visualisierung großer Informationsräume mit hilfreichen gründlichen, oft tabellarischen Zusammenfassungen und einem ausführlichen Glossar zusätzlicher Service: auf einer zu dem Buch eingerichteten Web-Site stehen Folien zur Verfügung

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

Hypertext for multi-media and full-text documents is rapidly developed on all fronts. For bibliographic information retrieval the applications are promising but pose several difficulties. Describes work conducted at the School of Library and Information Science at Univ. of Western Ontario the objective of which is to add the capability of a browsing search to an existing OPAC through the use of Windowed Hypertext Interface for Zippy Retrieval and Display (WHIZRD) software. Discusses the underlying retrieval capabilities of the system. Examines design problems and solutions and outlines future enhancements

Abstract

Human-computer interaction is a very important topic in studying computerized information retrieval systems, as it takes into account both the human searchers and the information system features. This entry surveys the major research streams and applications of interactive information seeking and retrieval. It also presents how the expectations and requirements for interactive information seeking and retrieval have been expanded and what the challenges are ahead for evaluating such systems.

Abstract

Explores interface design raised by the development and evaluation of Okapi, a highly interactive information retrieval system based on a probabilistic retrieval model with relevance feedback. It uses terms frequency weighting functions to display retrieved items in a best match ranked order; it can also find additional items similar to those marked as relevant by the searcher. Compares the effectiveness of automatic and interactive query expansion in different user interface environments. focuses on the nature of interaction in information retrieval and the interrelationship between functional visibility, the user's cognitive loading and the balance of control between user and system

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.
