- Abstract
- Visual Interfaces to Digital Libraries exploit the power of human vision and spatial cognition to help individuals mentally organize and electronically access and manage large and complex information spaces. They draw on progress in the field of information visualization and seek to shift the users' mental load from slow reading to faster perceptual processes such as visual pattern recognition.Based on two workshops, the book presents an introductory overview as well as a closing listing of the top ten problems in the area by the volume editors. Also included are 16 thoroughly reviewed and revised full papers organized in topical sections on visual interfaces to documents, document parts, document variants, and document usage data; visual interfaces to image and video documents; visualization of knowledge domains; cartographic interfaces to digital libraries; and a general framework.

- Abstract
- Für Webseiten ist, wie für alle interaktiven Anwendungen vom einfachen Automaten bis zur komplexen Software, die Benutzerfreundlichkeit von zentraler Bedeutung. Allerdings wird eine sinnvolle Benutzung von Informationsangeboten im World Wide Web häufig durch "cooles Design" unnötig erschwert, weil zentrale Punkte der Benutzerfreundlichkeit (Usability) vernachlässigt werden. Durch Usability Evaluation kann die Benutzerfreundlichkeit von Webseiten und damit auch die Akzeptanz bei den Benutzern verbessert werden. Ziel ist die Gestaltung von ansprechenden benutzerfreundlichen Webangeboten, die den Benutzern einen effektiven und effizienten Dialog ermöglichen. Das Buch bietet eine praxisorientierte Einführung in die Web Usability Evaluation und beschreibt die Anwendung ihrer verschiedenen Methoden.

- Abstract
- This book outlines the human side of the information seeking process, and focuses on the aspects of this process that can best be supported by the user interface. It describes the methods behind user interface design generally, and search interface design in particular, with an emphasis on how best to evaluate search interfaces. It discusses research results and current practices surrounding user interfaces for query specification, display of retrieval results, grouping retrieval results, navigation of information collections, query reformulation, search personalization, and the broader tasks of sensemaking and text analysis. Much of the discussion pertains to Web search engines, but the book also covers the special considerations surrounding search of other information collections.

- 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.

- Abstract
- Computers have become our companions in many of the activities we pursue in our life. They assist us, in particular, in searching relevant information that is needed to perform a variety of tasks, from professional usage to personal entertainment. They hold this information in a huge number of heterogeneous sources, either dedicated to a specific user community (e.g., enterprise databases) or maintained for the general public (e.g., websites and digital libraries). Whereas progress in basic information technology is nowadays capable of guaranteeing effective information management, information retrieval and dissemination has become a core issue that needs further accomplishments to achieve user satisfaction. The research communities in databases, information retrieval, information visualization, and human-computer interaction have already largely investigated these domains. However, the technical environment has so dramatically evolved in recent years, inducing a parallel and very significant evolution in user habits and expectations, that new approaches are definitely needed to meet current demand. One of the most evident and significant changes is the human-computer interaction paradigm. Traditional interactions relayed an programming to express user information requirements in formal code and an textual output to convey to users the information extracted by the system. Except for professional data-intensive application frameworks, still in the hands of computer speciahsts, we have basically moved away from this pattern both in terms of expressing information requests and conveying results. The new goal is direct interaction with the final user (the person who is looking for information and is not necessarily familiar with computer technology). The key motto to achieve this is "go visual." The well-known high bandwidth of the human-vision channel allows both recognition and understanding of large quantities of information in no more than a few seconds. Thus, for instance, if the result of an information request can be organized as a visual display, or a sequence of visual displays, the information throughput is immensely superior to the one that can be achieved using textual support. User interaction becomes an iterative query-answer game that very rapidly leads to the desired final result. Conversely, the system can provide efficient visual support for easy query formulation. Displaying a visual representation of the information space, for instance, lets users directly point at the information they are looking for, without any need to be trained into the complex syntax of current query languages. Alternatively, users can navigate in the information space, following visible paths that will lead them to the targeted items. Again, thanks to the visual support, users are able to easily understand how to formulate queries and they are likely to achieve the task more rapidly and less prone to errors than with traditional textual interaction modes.
The two facets of "going visual" are usually referred to as visual query systems, for query formulation, and information visualization, for result display. Visual Query Systems (VQSs) are defined as systems for querying databases that use a visual representation to depict the domain of interest and express related requests. VQSs provide both a language to express the queries in a visual format and a variety of functionalities to facilitate user-system interaction. As such, they are oriented toward a wide spectrum of users, especially novices who have limited computer expertise and generally ignore the inner structure of the accessed database. Information visualization, an increasingly important subdiscipline within the field of Human-Computer Interaction (HCI), focuses an visual mechanisms designed to communicate clearly to the user the structure of information and improve an the cost of accessing large data repositories. In printed form, information visualization has included the display of numerical data (e.g., bar charts, plot charts, pie charts), combinatorial relations (e.g., drawings of graphs), and geographic data (e.g., encoded maps). In addition to these "static" displays, computer-based systems, such as the Information Visualizer and Dynamic Queries, have coupled powerful visualization techniques (e.g., 3D, animation) with near real-time interactivity (i.e., the ability of the system to respond quickly to the user's direct manipulation commands). Information visualization is tightly combined with querying capabilities in some recent database-centered approaches. More opportunities for information visualization in a database environment may be found today in data mining and data warehousing applications, which typically access large data repositories. The enormous quantity of information sources an the World-Wide Web (WWW) available to users with diverse capabilities also calls for visualization techniques. In this article, we survey the main features and main proposals for visual query systems and touch upon the visualization of results mainly discussing traditional visualization forms. A discussion of modern database visualization techniques may be found elsewhere. Many related articles by Daniel Keim are available at http://www. informatik.uni-halle.de/dbs/publications.html.

- 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
- This study explores an image-based retrieval interface for drug information, focusing on usability for a specific population - seniors. Qualitative, task-based interviews examined participants' health information behaviors and documented search strategies using an existing database (www.drugs.com) and a new prototype that uses similarity-based clustering of pill images for retrieval. Twelve participants (aged 65 and older), reflecting a diversity of backgrounds and experience with Web-based resources, located pill information using the interfaces and discussed navigational and other search preferences. Findings point to design features (e.g., image enlargement) that meet seniors' needs in the context of other health-related information-seeking strategies (e.g., contacting pharmacists).

- 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
- Web Usability konnte sich als Forschungsbereich zunächst nur in größeren Firmen der Internet-Branche wie z. B. Icon Medialab etablieren. Mit zunehmender Konkurrenz und ersten Pleiten im E-Commerce entsteht die Einsicht oder bittere Erfahrung, dass bunte, multimediale Internetpräsenz nicht alles ist: Die Nutzungsqualität von Websites tritt in den Vordergrund und damit ein neuer Arbeitsmarkt für Informationsarchitekten und HCI- bzw. Usability-Spezialisten. Suchmaschinen sind eine besondere Kategorie von Website. Sie entstehen in einem Spannungsfeld zweier unterschiedlicher Interessen: Mit kommerziellen Websites teilen sie den Wettbewerb um Kunden und die Art der Kunden: den ungeduldigen gelegentlichen Anwender. Mit der akademischen Welt teilen sie das forschende Bemühen um die Optimierung von Features und Funktionen und die déformation professionelle der Eingeweihten. Am Beispiel zweier Untersuchungen wird deutlich, wie es der richtige 'Methodenmix' ermöglicht, bei der Evaluation der Nutzungsqualität von Suchmaschinen ganz unterschiedlicher Art (a) diesen Interessenkonflikt bewusst zu machen, (b) Empathie für die Nöte der Kunden zu entwickeln und c) allgemeingültige Kriterien zur Entwicklung gebrauchstauglicher Suchmaschinen aufzustellen. Beide Untersuchungen fanden im Rahmen des Projekts Jorschung und Forschungsumgebung für Web Usability« unter Mitwirkung von Studierenden am Fachbereich Bibliothek und Information der FH Hamburg statt

- Abstract
- Recent research highlights the potential relevance of emotions in interface design. People can no longer be modeled as purely goal-driven, task-solving agents: They also have affective motivations for their choices and behavior implying an extended mandate for search design. Absent from current Web design practice, however, is a pattern for emotive criticism and design reflecting these new directions. Further, discussion of emotions and Web design is not limited to visual design or aesthetic appeal: Emotions users have as they interact with information also have design implications. The author outlines a framework for understanding users' emotional states as they seek information on the Web. It is inspired largely by Carol Kuhlthau's (1991, 1993, 1999) work in library services, particularly her information searching process (ISP), which is adapted to Web design practice. A staged approach resembling traditional models of information seeking behavior is presented here as the basis for creating appropriate search and navigation systems. This user-centered framework is flexible and solution-oriented, enjoys longevity, and considers affective factors. Its aim is a more comprehensive, conceptual analysis of the user's entire information search experience.

- Abstract
- User interfaces of Web search engines reflect attributes of the underlying tools used to create them, rather than what we know about how people look for information. In this article, the author examines several characteristics of user search behavior: the variety of information-seeking goals, the cultural and situational context of search, and the iterative nature of the search task. An analysis of these characteristics suggests ways that interfaces can be redesigned to make searching more effective for users.

- 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
- Almost all Web searches are carried out while the user is sitting at a conventional desktop computer connected to the Internet. Although online, handheld, mobile search offers new possibilities, the fast-paced, focused style of interaction may not be appropriate for all user search needs. The authors explore an alternative, relaxed style for Web searching that asynchronously combines an offline handheld computer and an online desktop personal computer. They discuss the role and utility of such an approach, present a tool to meet these user needs, and discuss its relation to other systems.

- Abstract
- This paper presents a novel user interface that provides global visualizations of large document sets in order to help users to formulate the query that corresponds to their information needs and to access the corresponding documents. An important element of the approach we introduce is the use of concept hierarchies (CHs) in order to structure the document collection. Each CH corresponds to a facet of the documents users can be interested in. Users browse these CHs in order to specify and refine their information needs. Additionally the interface is based an OLAP principles and multidimensional analysis operators are provided to users in order to allow them to explore a document collection.

- Abstract
