    Rez. in Mitteilungen VÖB 57(2004) H.3/4, S.83-84 (O. Oberhauser): "Der Klappentext zu diesem Buch, das gleichzeitig als Cataloging & Classification Quarterly, Jg. 37, Nr. 1/2, veröffentlicht wurde, weiss mit eindrucksvollen Lobpreisungen bekannter anglo-amerikanischer Professoren aufzuwarten. Das Werk ist ein Sammelband mit 14 Artikeln von Autoren aus sechs Ländern, unter denen Kanada mit sechs Beiträgen klar dominiert (was nicht weiter überraschend ist, da die Herausgeberinnen von dort stammen). Das deklarierte Ziel des Bandes ist die Behandlung von Themen, die im Zusammenhang mit Information und Wissen in einem internationalisierten Kontext von Relevanz sind. Dies wird in vier thematisch gegliederten Abschnitten versucht. Das erste dieser Kapitel, General Bibliographic Systems, enthält vier Aufsätze, deren erster die Rolle allgemeiner und spezialisierter Klassifikationssysteme unter den Auspizien von Interoperabilität und weltweitem Zugriff reflektiert. Die anderen behandeln eine Adaptierung der DDC für die Verwendung bei der Erschliessung feministischer Literatur, die Probleme bei der Übersetzung von Klassifikationen von einer Sprache/Kultur in eine andere sowie den multilingualen Zugriff auf Dokumente in bibliographischen Datenbanken durch mehrsprachige, mit UDK-Zahlen verknüpfte Deskriptoren. Die zweite Sektion (ebenfalls vier Artikel) ist mit Information Organization in Knowledge Resources betitelt. Ihre konkreten Themen sind a) die Schwächen bibliothekarischer sachlicher Suchsysteme im internationalen Web-Kontext, b) die Recherche erziehungswissenschaftlicher Web-Ressourcen mittels "subject trees" bzw. in virtuellen Bibliotheken, c) Techniken für Text- und Data-Mining im Rahmen von Wissensorganisation und -ermittlung sowie d) Ansätze für die Wissensermittlung in nicht-bibliographischen Datenbanken.
    Im dritten Kapitel, Linguistics, Terminology, and Natural Language Processing, werden Anwendungen der Sprachtechnologie auf die Informationsrecherche und -verteilung über Sprachgrenzen hinweg, die Auswirkungen unterschiedlicher Sprachvarianten auf lexikalische Wissensmuster sowie ein "gateway" für fachübergreifende Wissensbanken, das auf einem Vokabular von Allgemeinbegriffen aus neun verschiedenen MetadatenSchemata beruht, behandelt. Der letzte Abschnitt trägt den etwas rätselhaften Titel Knowledge in the World and the World of Knowledge und enthält so heterogene Beiträge wie den Entwurf eines axiomatischen Systems für die semantische Integration von Ontologien, einen Vergleich der einflussreichen Knowledge-Management-Ansätze von Nonaka & Takeuchi (Japan) und Davenport & Prusak (USA) sowie einen Vergleich der Repräsentation amerikanischer und internationaler agrarökonomischer Themen in LCC (Library of Congress Classification) und NAICS (North American Industrial Classification System). Die eingangs erwähnten Lobeshymnen sind meiner Meinung nach ein wenig übertrieben. Das Buch ist nicht mehr und nicht weniger als ein recht typischer Sammelband mit wissenschaftlichen Artikeln von unterschiedlicher Qualität. Einige davon sind in verständlicher Sprache verfasst (wie etwa der kurze Beitrag über allgemeine vs. spezifische Klassifikationssysteme von J.-E. Mai), andere sind für normale Bibliothekare bzw. Informationswissenschaftler praktisch unlesbar (wie jener über Ontologien von R. E. Kent, der mehr als nur oberflächliche Kenntnisse der formalen Logik voraussetzt). Einige Artikel fand ich recht interessant, andere eher etwas langatmig. Die meisten Beiträge werden vermutlich eher bei wissenschaftlichen Vertretern unserer Disziplin auf Interesse stossen als bei Praktikern. Dass das Buch überein brauchbares Register verfügt, sei positiv vermerkt, zumal derlei heute nicht mehrselbstverständlich ist. Zur Anschaffung empfehlen würde ich diesen Band nicht nur Bibliotheken mit Spezialisierung auf Bibliotheks- und Informationswissenschaft, sondern auch allen grossen wissenschaftlichen Bibliotheken."

    Footnote
    Rez. in: Mitt VÖB 59(2006) H.2, S.83-88 (O. Oberhauser): "Dieser neue Sammelband möchte Interessenten aus den Bereichen Informationswissenschaft, Bibliothekswesen sowie Sozial- und Evolutionspsychologie aktuelle Entwicklungen und neue theoretische Ansätze auf dem Gebiet des menschlichen Informationsverhaltens-human information behavio(u)r bzw. kurz HIB - vermitteln. Es geht dabei um die komplexen Informationsprozesse, die in das alltägliche Sozialverhalten und die Lebensabläufe menschlicher Individuen eingebettet sind. Die beiden Herausgeber sind in diesem Teilbereich der Informationswissenschaft auch durch eine Reihe anderer Publikationen einschlägig ausgewiesen: Amanda Spink (vormals Universität Pittsburgh), die sich kürzlich selbst in aller Bescheidenheit als "world-class ICT researcher" beschrieb,' ist Professorin an der Technischen Universität Queensland (Australien); Charles Cole ist Research Associate (wissenschaftlicher Projektmitarbeiter) an der McGill University in Montreal und selbständiger Berater für Informationsdesign. Gemeinsam haben Spink und Cole zuletzt, ebenfalls bei Springer, eine weitere Aufsatzsammlung - New Directions in Cognitive Information Retrieval (2005) - herausgegeben. Das Buch versammelt zwölf Beiträge ("Kapitel"), die in fünf Sektionen dargeboten werden, wobei es sich allerdings bei den Sektionen 1 und 5 (= Kapitel 1 und 12) um Einleitung und Zusammenschau der Herausgeber handelt. Während erstere eigentlich nur eine Übersicht über die Gliederung und die Beiträge des Buches, die jeweils mit Abstracts beschrieben werden, darstellt, kann letztere als eigenständiger Beitrag gelten, der versucht, die in diesem Band angesprochenen Aspekte in einem vorläufigen HIB-Modell zu integrieren.
    Angesichts des skizzierten Umbruchs kann HIB wohl akzeptiert werden, doch ist es - wie dieses Buch zu suggerieren trachtet - wirklich notwendig, daneben auch noch IBEC (information behaviour in everyday contexts), ELIS (everyday life information seeking), HIOB (human information organizing behaviour), CIB (collaborative information behaviour), CIS&R (collaborative information seeking & retrieval) und HICB (human information co-ordinating behaviour) zu verwenden? Wohl kaum, doch wer wird bzw. kann ein solches Spamming verhindern? Würde der akademische Ernst nicht jede Schadenfreude verbieten, so könnte man konstatieren, dass diese Akronymenflut zu unnötigen Druckfehlern führt (z.B. p.172, wo sogar in einer Zwischenüberschrift "HIBO" statt "HIOB" zu lesen ist). In herausgeberischer Hinsicht ist weiter zu bemängeln, dass die meist ansehnlichen und sich naheliegenderweise zum Teil überschneidenden Literaturverzeichnisse der einzelnen Beiträge besser in einer Gesamtbibliographie mit konsistentem Zitierstil zu vereinen gewesen wären, zumal sie in der vorliegenden Form auch etwas inkonsistent und nicht fehlerfrei sind. In diese Richtung zu investieren wäre sinnvoller gewesen als in die Erstellung eines geradezu erbärmlichen Sachregisters (dessen Verriss den Rahmen dieser Besprechung sprengen würde), welches auf Herausgeber bzw. Lektorat - falls es letzteres überhaupt noch gibt - ein eher fahles Licht wirft. Abgesehen davon fielen mir nur einige fehlerhafte bzw. unvollständige Angaben der Institutszugehörigkeiten am Beginn der einzelnen Kapitel (z.B. p.113, p.203) sowie die nicht ganz homogen gestalteten Kurzbiographien der Verfasser/innen am Ende des Buches auf. Der Band selbst ist von gewohnt solider Springer-Machart und zielt schon aufgrund seines hohen Preis wohl nur auf institutionelle Käufer ab."

    Rez. in JASIST 57(2006) no.10, S.1412-1413 (R. W. White): "Information Retrieval Design is a textbook that aims to foster the intelligent user-centered design of databases for Information Retrieval (IR). The book outlines a comprehensive set of 20 factors. chosen based on prior research and the authors' experiences. that need to he considered during the design process. The authors provide designers with information on those factors to help optimize decision making. The book does not cover user-needs assessment, implementation of IR databases, or retries al systems, testing. or evaluation. Most textbooks in IR do not offer a substantive walkthrough of the design factors that need to be considered Mien des eloping IR databases. Instead. they focus on issues such as the implementation of data structures, the explanation of search algorithms, and the role of human-machine interaction in the search process. The book touches on all three, but its focus is on designing databases that can be searched effectively. not the tools to search them. This is an important distinction: despite its title. this book does not describe how to build retrieval systems. Professor Anderson utilizes his wealth of experience in cataloging and classification to bring a unique perspective on IR database design that may be useful for novices. for developers seeking to make sense of the design process, and for students as a text to supplement classroom tuition. The foreword and preface. by Jessica Milstead and James Anderson. respectively, are engaging and worthwhile reading. It is astounding that it has taken some 20 years for anyone to continue the stork of Milstead and write as extensively as Anderson does about such an important issue as IR database design. The remainder of the book is divided into two parts: Introduction and Background Issues and Design Decisions. Part 1 is a reasonable introduction and includes a glossary of the terminology that authors use in the book. It is very helpful to have these definitions early on. but the subject descriptors in the right margin are distracting and do not serve their purpose as access points to the text. The terminology is useful to have. as the authors definitions of concepts do not lit exactly with what is traditionally accepted in IR. For example. they use the term 'message' to icier to what would normally be called .'document" or "information object." and do not do a good job at distinguishing between "messages" and "documentary units". Part 2 describes components and attributes of 1R databases to help designers make design choices. The book provides them with information about the potential ramifications of their decisions and advocates a user-oriented approach to making them. Chapters are arranged in a seemingly sensible order based around these factors. and the authors remind us of the importance of integrating them. The authors are skilled at selecting the important factors in the development of seemingly complex entities, such as IR databases: how es er. the integration of these factors. or the interaction between them. is not handled as well as perhaps should be. Factors are presented in the order in which the authors feel then should be addressed. but there is no chapter describing how the factors interact. The authors miss an opportunity at the beginning of Part 2 where they could illustrate using a figure the interactions between the 20 factors they list in a way that is not possible with the linear structure of the book.

    Enthält u.a. folgende Aussage von J. Aitchison u. S. Dextre Clarke: "We face a paradox. Ostensibly, the need and the opportunity to apply thesauri to information retrieval are greater than ever before. On the other hand, users resist most efforts to persuade them to apply one. The drive for interoperability of systems means we must design our vocabularies for easy integration into downstream applications such as content management systems, indexing/metatagging interfaces, search engines, and portals. Summarizing the search for vocabularies that work more intuitively, we see that there are trends working in opposite directions. In the hugely popular taxonomies an the one hand, relationships between terms are more loosely defined than in thesauri. In the ontologies that will support computer-to-computer communications in AI applications such as the Semantic Web, we see the need for much more precisely defined term relationships."
