    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 Internet is a medium for education, entertainment, communication, and personal expression. User behavior has developed three main modalities for using this medium effectively - searching, browsing, and monitoring - which are supported to different degrees by conventional tools. Understanding the nature of the interaction allows us to design and implement a system called Mitsukeru to support browsing behaviors, while retaining the free-form movements between other interaction styles. The system uses agent-based modeling and look-ahead to provide informative yet nonintrusive guidance to the user, and is described in detail.

    "Wenn Marita Kessler im Internet surft, braucht sie beide Hände. Und ihre Ohren. Denn sie muss hören, was sich auf dem Bildschirm abbildet. Die 47-Jährige ist seit ihrer Geburt blind. Mit Hilfe bestimmter PC-Ausstattungen kann sie den Computer fast genauso nutzen wie Sehende. Bereits seit 19 Jahren arbeitet Marita Kessler in der Firma Audiodata in Oberhausen bei Speyer - und zwar hauptsächlich am Rechner. Unter anderem beantwortet sie die Zuschriften vieler blinder und sehbehinderter Menschen, die sich an das Unternehmen wenden - in der Hoffnung, Erleichterung in hrem Alltag oder ihrer Freizeit zu finden. Der Betrieb, ,der in einem ehemaligen Schweinestall seinen Hauptsitz hat, produziert seit 1983 Computer-Hilfsmittel für Blinde und Sehbehinderte. Firmengründer Joachim Frank ist selbst sehbehindert und hat eigene Erfahrungen in seine Arbeit einfließen lassen. "Das erste Produkt war ein akustisches Blinden-Text-System, mit dem Blinde auch Texte verarbeiten können", erinnert er sich. "Doch dann haben wir gemerkt, dass es eigentlich zum viel mehr geht." Nämlich dass Menschen ohne Augenlicht, die gesamten Möglichkeiten des PCs intensiv nutzen können. Heute stellt Frank mit rund 50 sehenden und blinden Mitarbeitern 14 Hilfsmittel her - und zwar neun Geräte und fünf Programme. Beispielsweise die Software Blindows. Sie übersetzt die grafische Windows-Oberfläche in hörbare Sprache oder in die Blindenschrift Braille. Marita Kessler zeigt an ihrem Arbeitsplatz die Funktionsweise des Programms. Wenn sie ein neues Word-Dokument öffnen will, bewegt sie den Cursor mit der Tastatur auf die Menüleiste. Die Befehle werden von einer elektronischen Stimme mitgesprochen und gleichzeitig auf einer Schiene an der Unterseite der Tastatur in Braille-Schrift wiedergegeben. Marita Kessler kann also auf die Stimme hören und mit den Fingerspitzen die sich hebenden und senkenden Pünktchen spüren. Es ist für sie kein Problem, längere Texte am Schirm zu lesen oder Mails zu beantworten. Damit es flotter geht, stellt sie gerne die Geschwindigkeit der lesenden Stimme schneller - und lauscht nun einem Text, der in ungeübten Ohren so klingt, als würde man eine Kassette im Vorlauf abspielen. Doch Marita Kessler versteht jedes Wort. Nicht weniger beeindruckend ist ihre Bewegungssicherheit auf dem Monitor. Da-zu bedient sie mit beiden Händen einen vertikal sowie einen horizontal zur Tastatur angebrachten Schieber. Je nach Standort werden unterschiedliche Töne erzeugt. Leerzeilen erkennt Marita Kessler zum Beispiel an einem tiefen, Cursorzeilen an einem hellen Ton. "Die taktil-akustische Seiten-Orientierung erfasst den Bildschirm in zwei Dimensionalen", erklärt der Erfinder Joachim Frank. "Blinde wollen ja nicht, dass ihnen der Bildschirm wie ein Brief von oben nach unten vorgelesen wird, sondern sie wollen gezielt auf etwas zugreifen." Mit dem Hilfsmittel seien Blinde in der Lage, den Punkt ihrer Aufmerksamkeit selbst zu setzen. Was besonders beim Surfen im Internet sinnvoll angewendet werden kann. Denn gerade im Netz sucht man oft nach einer bestimmten Information und lässt überflüssigeTexte undLinks unbeachtet. Oder Bilder. Die sind für Blinde besonders störend, da sie nicht übersetzt werden können. An dieser Stelle erleichtert eine weitere Entwicklung Sehbehinderten das Dasein im Netz. Der Webformator blendet alle Bilder und Grafiken aus und stellt die komplette Internetseite in Textform dar. So können - wiederum mit Hilfe von Blindows - auch Links, die sich eventuell unter Icons oder Bildern verbergen, gezielt angewählt werden. Die Kombination der Hilfsmittel erlaubt dem Rennsport Fan Marita Kessler unter anderem, eine Formel-l-Seite mit Grafiken und Ergebnistabellen ohne Probleme zu lesen.
    Während Blinde das Leben im Cyberspace mit diesen Hilfsmitteln nahezu mühelos bewältigen können, bietet der Alltag nach wie vor Hürden, die sie nur mit der Unterstützung von Sehenden überwinden. Halte ich gerade die Dose mit den Erbsen oder das Hundefutter in der Hand? Habe ich zwei verschiedenfarbige Socken an? Auch eine handgeschriebene Postkarte müssen sich gehbehinderte immer noch vorlesen lassen-was voraussetzt, dass gerade jemand da ist. Um die Abhängigkeit der Blinden von ihrem Umfeld zu lockern, hat sich Joachim Frank "Klickblick" ausgedacht. Die Erfindung erinnert in ihrer Kreativität ein wenig an die verrückten Schöpfzungen von Walt Disneys Daniel Düsentrieb. Im Gegensatz zu den Einfällen der Erfinder-Ente funktioniert Franks Entwicklung aber tatsächlich. Was Marita Kessler beweist. Mit Hilfe einer Webcam, die sie an ihrem PC angebracht hat, und der nötigen Software ist sie in der Lage, ein Bild der Postkarte ins Internet zu übermitteln. Daraufhin kann ihr ein so genannter Blicker, der auch online ist, die Postkarte vorlesen - entweder über eine TelefonInternet-Verbindung oder in Form eines getippten Textes. "Somit können Blinde jederzeit auf die Unterstützung Sehender zurückgreifen - auch wenn gerade keiner in der Nähe ist", erklärt Joachim Frank. Damit Klickblick funktioniert, muss sich der Blicker lediglich die entsprechende kostenlose Software herunterladen und ein Mikrofon fier die Sprachverbindung anschaffen. Der blinde Frager benötigt zusätzlich die Webcam und muss - je nach Benutzungsfrequenz - einen kleinen Be-trag bezahlen. Natürlich brauchen beide einen Internet-Zugang oder zumindest einen Zugriff zu einem lokalen Netzwerk. Derzeit ist die aktive Klickblick-Gemeinschaft überschaubar. An der Testphase des Projekts, das im vergangenen Jahr mit dem "Start Social, einem Sozialpreis der Bundesregierung, ausgezeichnet wurde, beteiligen sich seit Januar 20 Blinde und 50 Blicker. Die Gefahr ist noch groß, dass in dem Moment, in dem der Blinde sich das Auge eines anderen Users leihen möchte, keiner online ist. Deshalb will Joachim Frank mehr sehende Menschen für seine Idee begeistern. Unterstützung von den deutschen Blinden-Selbsthilfeverbänden hat er bereits: Mit ihnen hat Frank den gemeinnützigen Verein "Klickblick Plus" gegründet. Wir haben uns hauptsächlich die' Förderung von Klickblick und die internationale Verbreitung der Erfindung zum Ziel gesetzt", erklärt Frank. Gerade hat er Klickblick auf einer Messe in Los Angeles vorgestellt. "Wir, wollen keine verschiedensprachigen Netzwerke, sondern eine einzige Community einrichten, beschreibt er. Dort könne man sich mit seiner Muttersprache und seinen Zweitsprache registrieren. "Das wird dann zu einer transnationalen Brücke führen°, hofft Frank. Die Namen für Klickblick, die sind allerdings noch unterschiedlich: Auf Spanisch heißt die Entwicklung "Los ojos", die Augen Und das Englische kommt der eigentlichen: Bedeutung, nämlich der Idee des ausgeliehenen Auges, vielleiht am nächsten: Hier heißt Klickblick schlicht "See for me"."

    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
    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
    Trotz ihrer Vorteile gegenüber herkömmlichen Hypertext-Hilfen werden adaptive Hilfesysteme in kommerziellen Anwendungen nur sehr selten eingesetzt. Die Hauptgründe dafür liegen in einer fehlenden allgemeingültigen Konzeption beim Entwurf einer adaptiven Hilfe und den fehlenden Software-Werkzeugen, die die Entwicklung einer solchen Hilfe auf dieser Basis unterstützen. Zur Lösung dieser Problematik wird mit GERSHWIN eine Konzeption zur Entwicklung eines adaptiven Hilfesystems vorgestellt. Um eine entsprechende individuelle Hilfestellung zu ermöglichen, wird das Benutzerverhalten in der Anwendung beobachtet und mit Hilfe eines Planerkennungsverfahrens ausgewertet. GERSHWIN beschreibt eine Vorgehensweise für die Entwicklung eines adaptiven Hilfesystems und stellt für den praktischen Einsatz auch eine Programmbibliothek zur Verfügung. Voraussetzung für den Einsatz von GERSHWIN ist der Zugriff auf den Quellcode der Applikation, die eine adaptive GERSHWIN-Hilfe erhalten soll. Die Schnittstelle ist hierbei jedoch denkbar einfach - es werden lediglich vier Funktionen zur Kommunikation mit dem Hilfesystem benötigt. Existiert bereits ein Hilfesystem zur Applikation, so wird dieses durch die GERSHWIN-Hilfe vollständig ersetzt. Grundlage für die Planerkennung ist eine sogenannte Planbasis, die angibt, welche Aufgaben mit der Applikation wie erledigt werden können. Diese Inhalte werden anhand der Analyse der Funktionalitäten der Applikation und anhand von Benutzertests ermittelt. Zur Eingabe dieser Pläne enthält GERSHWIN einen visuellen Planeditor, der die Kernkomponenten zur Planerkennung und zur Visualisierung der Hilfeinformationen ergänzt. Implementierte Anwendungsbeispiele für die GERSHWIN-Hilfe sind die Unterstützung für eine sozialwissenschaftliche Recherchesoftware (GESINE-Thesaurus) und ein Kursblockungsprogramm (daVinci-Kursplan).

    Abstract
    A novel and complex form of information access is cross-language information retrieval: searching for texts written in foreign languages based on native language queries. Although the underlying technology for achieving such a search is relatively well understood, the appropriate interface design is not. The authors present three user evaluations undertaken during the iterative design of Clarity, a cross-language retrieval system for lowdensity languages, and shows how the user-interaction design evolved depending on the results of usability tests. The first test was instrumental to identify weaknesses in both functionalities and interface; the second was run to determine if query translation should be shown or not; the final was a global assessment and focused on user satisfaction criteria. Lessons were learned at every stage of the process leading to a much more informed view of what a cross-language retrieval system should offer to users.

    Abstract
    This article investigates a new, effective browsing approach called metabrowsing. It is an alternative for current information retrieval systems, which still face six prominent difficulties. We identify and classify the difficulties and show that the metabrowsing approach alleviates the difficulties associated with query formulation and missing domain knowledge. Metabrowsing is a high-level way of browsing through information: instead of browsing through document contents or document surrogates, the user browses through a graphical representation of the documents and their relations to the domain. The approach requires other cognitive skills from the user than what is currently required. Yet, a user evaluation in which the metabrowsing system was compared with an ordinary query-oriented system showed only some small indicatory differences in effectiveness, efficiency, and user satisfaction. We expect that more experience with metabrowsing will result in a significantly better performance difference. Hence, our conclusion is that the development of new cognitive skills requires some time before the technologies are ready to be used.

    Abstract
    The Online Public Access Catalog (OPAC) is an information retrieval system characterized by short bibliographic records, mainly of books, journals, and audiovisual materials available in a particular library. This, coupled with a Boolean search interface and a heterogeneous user population with diverse needs, presents special problems for subject searching by end users. To perform effective subject searching in the OPAC system requires a wide range of knowledge and skills. Various approaches to improving the OPAC design for subject searching have been proposed and are reviewed in this entry. The trend toward Web-based OPAC interfaces and the developments in Internet and digital library technologies present fresh opportunities for enhancing the effectiveness of the OPAC system for subject searching.

    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).
