Abstract

This book offers a comprehensive and consistent mathematical approach to information retrieval (IR) without which no implementation is possible, and sheds an entirely new light upon the structure of IR models. It contains the descriptions of all IR models in a unified formal style and language, along with examples for each, thus offering a comprehensive overview of them. The book also creates mathematical foundations and a consistent mathematical theory (including all mathematical results achieved so far) of IR as a stand-alone mathematical discipline, which thus can be read and taught independently. Also, the book contains all necessary mathematical knowledge on which IR relies, to help the reader avoid searching different sources. The book will be of interest to computer or information scientists, librarians, mathematicians, undergraduate students and researchers whose work involves information retrieval.

Rez. in: Information Research, 9(3), review no. R129 (T.D. Wilson): "The first edition of this book was published ten years ago and rapidly become something of a classic in the field of information seeking behaviour. It is good to see the second edition which incorporates not only the work the author has done since 1993, but also related work by other researchers. Kuhlthau is one of the most cited authors in the field and her model of the information search process, involving stages in the search and associated feelings, has been used by others in a variety of contexts. However, what makes this book different (as was the case with the first edition) is the author's dedication to the field of practice and the book's sub-title demonstrates her commitment to the transfer of research. In Kuhlthau's case this is the practice of the school library media specialist, but her research has covered students of various ages as well as a wide range of occupational groups. Because the information search model is so well known, I shall concentrate in this review on the relationship between the research findings and practice. It is necessary, however, to begin with the search process model, because this is central. Briefly, the model proposes that the searcher goes through the stages of initiation, selection, exploration, formulation, collection and presentation, and, at each stage, experiences various feelings ranging from optimism and satisfaction to confusion and disappointment. Personally, I occasionally suffer despair, but perhaps that is too extreme for most!
It is important to understand the origins of Kuhlthau's ideas in the work of the educational theorists, Dewey, Kelly and Bruner. Putting the matter in a rather simplistic manner, Dewey identified stages of cognition, Kelly attached the idea of feelings being associated with cognitive stages, and Bruner added the notion of actions associated with both. We can see this framework underlying Kuhlthau's research in her description of the actions undertaken at different stages in the search process and the associated feelings. Central to the transfer of these ideas to practice is the notion of the 'Zone of Intervention' or the point at which an information seeker can proceed more effectively with assistance than without. Kuhlthau identifies five intervention zones, the first of which involves intervention by the information seeker him/herself. The remaining four involve interventions of different kinds, which the author distinguishes according to the level of mediation required: zone 2 involves the librarian as 'locater', i.e., providing the quick reference response; zone 3, as 'identifier', i.e., discovering potentially useful information resources, but taking no further interest in the user; zone 4 as 'advisor', i.e., not only identifying possibly helpful resources, but guiding the user through them, and zone 5 as 'counsellor', which might be seen as a more intensive version of the advisor, guiding not simply on the sources, but also on the overall process, through a continuing interaction with the user. Clearly, these processes can be used in workshops, conference presentations and the classroom to sensitise the practioner and the student to the range of helping strategies that ought to be made available to the information seeker. However, the author goes further, identifying a further set of strategies for intervening in the search process, which she describes as 'collaborating', 'continuing', 'choosing', 'charting', 'conversing' and 'composing'. 'Collaboration' clearly involves the participation of others - fellow students, work peers, fellow researchers, or whatever, in the search process; 'continuing' intervention is associated with information seeking that involves a succession of actions - the intermediary 'stays with' the searcher throughout the process, available as needed to support him/her; 'choosing', that is, enabling the information seeker to identify the available choices in any given situation; 'charting' involves presenting a graphic illustration of the overall process and locating the information seeker in that chart; 'conversing' is the encouragement of discussion about the problem(s), and 'composing' involves the librarian as counsellor in encouraging the information seeker to document his/her experience, perhaps by keeping a diary of the process.
Together with the zones of intervention, these ideas, and others set out in the book, provide a very powerful didactic mechanism for improving library and information service delivery. Of course, other things are necessary - the motivation to work in this way, and the availability resources to enable its accomplishment. Sadly, at least in the UK, many libraries today are too financially pressed to do much more than the minimum helpful intervention in the information seeking process. However, that should not serve as a stick with which to beat the author: not only has she performed work of genuine significance in the field of human information behaviour, she has demonstrated beyond question that the ideas that have emerged from her research have the capability to help to deliver more effective services."

Rez. in: Information - Wissenschaft & Praxis 56(2005) H.3, S.205 (E. Simon): "Wenn eine ältere Dame, so ab 50 aufwärts einen der großen Mediamärkte in Berlin wie z.B. Mediamarkt oder Saturn mit einem bestimmten Wunsch aufsucht, dessen Formulierung aber nicht auf profundem informationstechnologischem Wissen beruht, dann fällt sie entweder in ein schwarzes Loch oder sie hat den großen Wunsch, falls sie etwas furchtsam ist, dass sich ein großes schwarzes Loch auftut, in dem sie verschwinden kann. In den meisten Fällen wird sie ohne das gewünschte Produkt mit dem leichten Gefühl der Verzweiflung diese informationstechnologischen Kundentempel verlassen. Diese schwarzen Löcher hat der Autor mit seiner Titelwahl nicht gemeint, obwohl "im Sog der Informations- und Wissensindustrie" schon die Hilflosigkeit diese Gefühls trifft, sondern es geht ihm um die Kreation eines Schemas für die Verortung von Informationswissenschaft und Informationswirtschaft. Ratzek stellt fest, dass Informationsarbeit zu einem Ouasi-Monopol von Programmierern, Netzwerkingenieuren und - möchten wir hinzufügen - von unwissenden arroganten Verkäufern und Beratern mutiert, wobei die Leistungen der Informationsfachleute wie Bibliothekaren und der sogenannten Information Professionals zu einer Nebensächlichkeit verkommen. Die Arbeit der Informationsfachleute versteckt sich hinter dem, was der Verfasser "Informatikmimikry" nennt mit den Folgen Entmündigung - das können andere viel besser - und letztendlich Verlust des Image. Diesem können die BID-Professionen nur durch Kampagnen für die Public Awareness begegnen, wie sie in dem vom Autor herausgegebenen Buch Spielball Bibliotheken (Berlin 2004) dargestellt wurden. Außerordentlich erschwerend für die Entwicklung des Faches ist aber, dass alles, "Daten, Information und Wissen in einen Topf geworden wird" und dieser Eintopf dann als "Information" oder, weil es gerade angesagt ist, als "Wissen" serviert wird. Daher lässt Ratzek sich nicht darauf ein, den Gegensatz oder die Kongruenz zwischen Information und Wissen näher zu definieren, wie es z.B. in der angelsächsischen Literatur vorherrschend war und immer noch ist, wenn auch damit eine mehr auf case work oder Managementaufgaben im angelsächsischen Sinne gerichtete Blickrichtung gemeint ist, wie es z.B. in dem ausgezeichnet einsetzbaren Buch von Angela Abell und Nigel Oxbrow: Competing with Knowledge, The Information professional in the Knowledge Management Age. (tfpl/LA 1999) deutlich wird. Der Ansatz von Ratzek ist wissenschaftlich und dabei transdisziplinär. Er gibt nicht nur einen profunden Überblick über den Stand der Informationswissenschaft als Ausbildungsdisziplin, sondern er zieht auch die Entwicklungslinien z.B. zu den Grundlagen der Semiotik als Basis unserer durch das Icon beherrschten Informationsumwelt. Er setzt sich auch mit der Theorienbildung durch Gernot Wersig und Rainer Kuhlen auseinander und man würde sich diese knappen und präzisen Ausführungen in die Köpfe mancher Politiker wünschen, die heute noch einem diffusen Bildungsbegriff nachhängen, ohne die dafür notwendige Informationsinfrastruktur im Blick zu haben: So zitiert Ratzek nach Wersig:
