Abstract

Die Analyse des Verhaltens von Benutzern von Informationssystemen stellt einen Kern der Informationswissenschaft dar. Die Sammlung von umfangreichen Verhaltensdaten fällt mit den heutigen technischen Möglichkeiten leicht. Der Artikel fasst Möglichkeiten und Chancen der Analyse von Log-Dateien zusammen. Der Track LogCLEF wird vorgestellt, der Forschern erstmals die Möglichkeit eröffnet, mit den denselben Log-Dateien und somit vergleichend arbeiten zu können. Die Datengrundlage und einige Ergebnisse von LogCLEF werden vorgestellt.

Abstract

Der Artikel betrachtet anhand einer Studie zum Benutzerverhalten bei der Online-Katalogrecherche den gegenwärtigen Stellenwert und das zukünftige Potential der Web-OPACs. Dabei werden zunächst die Ergebnisse einer quantitativen Logfile-Analyse sowie qualitativer Benutzertests erörtert, bevor aktuelle Entwicklungen der Webtechnologie, die unter den Schlagworten Web 2.0 und Web 3.0 propagiert werden, im Zusammenhang mit der Online-Recherche und der Entwicklung neuartiger Suchverfahren kurz diskutiert werden.

Abstract

Im Rahmen einer Überarbeitung und Erweiterung des Internet-Auftritts der Stadtbibliothek Stuttgart wurde die Bedienerfreundlichkeit (usability) des Online-Katalogs (OPAC) der Bücherei wissenschaftlich getestet, um daraus Kriterien für eine mögliche Verbesserung herauszuarbeiten. Anfragen von Nutzern der Bibliothek und Beobachtungen der Bibliotheksmitarbeiterinnen hatten in der Vergangenheit deutlich gemacht, dass es offensichtlich nicht allen Nutzern problemlos möglich ist, den Katalog effektiv und angemessen zu nutzen. Da es sich beim webbasierten Online-Katalog um das Kernstück der Website der Bibliothek handelt, hatte seine Optimierung größte Priorität. Das Ziel sollte sein, einen Katalog anzubieten, der von sämtlichen potentiellen Nutzern mit den unterschiedlichsten Vorkenntnissen mit möglichst geringem Aufwand und einem optimalen Suchergebnis bedient werden kann.

Abstract

In information needs, seeking and use (INSU) research, individuals have most commonly been perceived as users (e.g., Kuhlthau, 1991; Dervin & Nilan, 1986; Dervin, 1989; Belkin, 1980). The concept user originates from the user of libraries and other information services and information systems. Over the years the scope of the concept has become wider and it is nowadays often understood in the sense of seekers of information (e.g., Wilson, 1981; Marchionini, 1995) and users of information (e.g., Streatfield, 1983). Nevertheless, the concept has remained ambiguous by being on the one hand universal and on the other hand extremely specific. The purpose of this paper is to map and evaluate views on people whose information behaviour has been in one way or another the core of our research area. The goal is to shed some light on various relationships between the different aspects of doers in INSU studies. The paper is inspired by Dervin's (1997) analysis of context where she identified among other themes the nature of subject by contrasting a `transcendental individual' with a `decentered subject', and Talja's (1997) presentation about constituting `information' and `user' from the discourse analytic viewpoint as opposed to the cognitive viewpoint. Instead of the metatheoretical approach applied by Dervin and Talja, a more concrete approach is valid in the present analysis where no direct arguments for or against the underlying metatheories are itemised. The focus is on doers in INSU studies leaving other, even closely-related concepts (i.e., information, information seeking, knowledge etc.), outside the scope of the paper.

Abstract

This article reports the findings of a qualitative research study that examined professional image users' knowledge of, and interest in using, content-based image retrieval (CBIR) systems in an attempt to clarify when and where CBIR methods might be applied. The research sought to determine the differences in the perceived usefulness of CBIR technologies among image user groups from several domains and explicate the reasons given regarding the utility of CBIR systems for their professional tasks. Twenty participants (archaeologists, architects, art historians, and artists), individuals who rely on images of cultural materials in the performance of their work, took part in the study. The findings of the study reveal that interest in CBIR methods varied among the different professional user communities. Individuals who showed an interest in these systems were primarily those concerned with the formal characteristics (i.e., color, shape, composition, and texture) of the images being sought. In contrast, those participants who expressed a strong interest in images of known items, images illustrating themes, and/or items from specific locations believe concept-based searches to be the most direct route. These image users did not see a practical application for CBIR systems in their current work routines.

Abstract

The results of a small qualitative study of gay and lesbian information users suggest that facet analysis as it is increasingly practised in the field of information architecture provides a promising avenue for improving information access to gay and lesbian information resources. Findings indicated that gay and lesbian information users have an acute sense of categorization grounded in the need to identify gay-positive physical and social spaces, and in their finely-honed practices of detecting gay "facets" to general information themes. They are also, however, very flexible and adaptable in their application of gay-related facet values, which suggests that browsing systems will have to be designed with considerable care.
