Abstract

Die Vermittlung von Informationskompetenz wird künftig zu den Kernaufgaben der Bibliotheken gehören müssen. Dies ist auch eines der Hauptarbeitsfelder des Rezensenten, der aus eigener Praxis sieht, welche Schwierigkeiten sich hierbei finden: Viele Klienten erkennen ihren eigenen Informationsbedarf nicht, können ein fachliches nicht von einem informatorischen Problem trennen, sind nicht in der Lage, für ihr spezifisches Problem potenzielle Informationsquellen zu finden und haben vor allem Probleme, die Verbindung zwischen elektronischer und gedruckter WeIt zu schaffen, die somit praktisch unverbunden nebeneinander existieren (vgl. Rainer Strzolka: Vermittlung von Informationskompetenz als Informationsdienstleistung? Vortrag, FH Köln, Fakultät für Informations- und Kommunikationswissenschaften, Institut für Informationswissenschaft, am 31. Oktober 2003). Der Brückenschlag zwischen diesen beiden Welten gehört zu den Aufgaben professioneller Informationsvermittler, die nicht nur in der Digitalwelt firm sein müssen, aber auch dort. Nicht zuletzt müssen die gefundenen Informationen ergebnisorientiert genutzt und kritisch bewertet werden und die gefundenen Antworten zur Problemlösung eingesetzt werden. Die Informationslandschaft ist mit ihren verschiedenen Wissensmarktplätzen und Informationsräumen inzwischen so komplex geworden, dass eine kleine Handreichung dazu geeignet erscheint, vor allem die eigene Position des Informationsvermittlers zu überdenken. Zudem ist die aktive Informationsvermittlung noch ein dürres Feld in Deutschland. Die vorliegende kleine Erfahrungsstudie schickt sich an, dies zu ändern. Der Ansatz geht davon aus, dass jeder Vermittler von Medienkompetenz Lehrer wie Lernender zugleich ist; die Anlage ist wie bei allen BibSpider-Publikationen international ausgerichtet. Der Band ist komplett zweisprachig und versammelt Erfahrungsberichte aus der Bundesrepublik Deutschland, den USA und Südafrika, die eher als Ansatz zur Bewusstseinsbildung denn als Arbeitsanleitung gedacht sind. Eingeleitet wird der Band von einer terminologischen Herleitung des Begriffs aus dem Angelsächsischen und den verschiedenen Bedeutungsebenen, die durch unterschiedliche Bildungs- und Informationskulturen bedingt sind. Angerissen werden verschiedene Arbeitsgebiete und -erfahrungen.

Rez. in: JASIST 54(2003) no.9, S.905-906 (C.A. Badurek): "Visual approaches for knowledge discovery in very large databases are a prime research need for information scientists focused an extracting meaningful information from the ever growing stores of data from a variety of domains, including business, the geosciences, and satellite and medical imagery. This work presents a summary of research efforts in the fields of data mining, knowledge discovery, and data visualization with the goal of aiding the integration of research approaches and techniques from these major fields. The editors, leading computer scientists from academia and industry, present a collection of 32 papers from contributors who are incorporating visualization and data mining techniques through academic research as well application development in industry and government agencies. Information Visualization focuses upon techniques to enhance the natural abilities of humans to visually understand data, in particular, large-scale data sets. It is primarily concerned with developing interactive graphical representations to enable users to more intuitively make sense of multidimensional data as part of the data exploration process. It includes research from computer science, psychology, human-computer interaction, statistics, and information science. Knowledge Discovery in Databases (KDD) most often refers to the process of mining databases for previously unknown patterns and trends in data. Data mining refers to the particular computational methods or algorithms used in this process. The data mining research field is most related to computational advances in database theory, artificial intelligence and machine learning. This work compiles research summaries from these main research areas in order to provide "a reference work containing the collection of thoughts and ideas of noted researchers from the fields of data mining and data visualization" (p. 8). It addresses these areas in three main sections: the first an data visualization, the second an KDD and model visualization, and the last an using visualization in the knowledge discovery process. The seven chapters of Part One focus upon methodologies and successful techniques from the field of Data Visualization. Hoffman and Grinstein (Chapter 2) give a particularly good overview of the field of data visualization and its potential application to data mining. An introduction to the terminology of data visualization, relation to perceptual and cognitive science, and discussion of the major visualization display techniques are presented. Discussion and illustration explain the usefulness and proper context of such data visualization techniques as scatter plots, 2D and 3D isosurfaces, glyphs, parallel coordinates, and radial coordinate visualizations. Remaining chapters present the need for standardization of visualization methods, discussion of user requirements in the development of tools, and examples of using information visualization in addressing research problems.

... TREC: Experiment and Evaluation in Information Retrieval is a reliable and comprehensive review of the TREC program and has been adopted by NIST as the official history of TREC (see http://trec.nist.gov). We were favorably surprised by the book. Well structured and written, chapters are self-contained and the existence of references to specialized and more detailed publications is continuous, which makes it easier to expand into the different aspects analyzed in the text. This book succeeds in compiling TREC evolution from its inception in 1992 to 2003 in an adequate and manageable volume. Thanks to the impressive effort performed by the authors and their experience in the field, it can satiate the interests of a great variety of readers. While expert researchers in the IR field and IR-related industrial companies can use it as a reference manual, it seems especially useful for students and non-expert readers willing to approach this research area. Like NIST, we would recommend this reading to anyone who may be interested in textual information retrieval."

Weitere Rez. in: JASIST 58(2007) no.2, S.303 (D.E. Agosto): "Due to the brevity of the entries, they serve more as introductions to a wide array of theories than as deep explorations of a select few. The individual entries are not as deep as those in more traditional reference volumes, such as The Encyclopedia of Library and Information Science (Drake, 2003) or The Annual Review of Information Science and Technology (ARIST) (Cronin, 2005), but the overall coverage is much broader. This volume is probably most useful to doctoral students who are looking for theoretical frameworks for nascent research projects or to more veteran researchers interested in an introductory overview of information behavior research, as those already familiar with this subfield also will probably already be familiar with most of the theories presented here. Since different authors have penned each of the various entries, the writing styles vary somewhat, but on the whole, this is a readable, pithy volume that does an excellent job of encapsulating this important area of information research."
