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.
In 13 chapters, Part Two provides an introduction to KDD, an overview of data mining techniques, and examples of the usefulness of data model visualizations. The importance of visualization throughout the KDD process is stressed in many of the chapters. In particular, the need for measures of visualization effectiveness, benchmarking for identifying best practices, and the use of standardized sample data sets is convincingly presented. Many of the important data mining approaches are discussed in this complementary context. Cluster and outlier detection, classification techniques, and rule discovery algorithms are presented as the basic techniques common to the KDD process. The potential effectiveness of using visualization in the data modeling process are illustrated in chapters focused an using visualization for helping users understand the KDD process, ask questions and form hypotheses about their data, and evaluate the accuracy and veracity of their results. The 11 chapters of Part Three provide an overview of the KDD process and successful approaches to integrating KDD, data mining, and visualization in complementary domains. Rhodes (Chapter 21) begins this section with an excellent overview of the relation between the KDD process and data mining techniques. He states that the "primary goals of data mining are to describe the existing data and to predict the behavior or characteristics of future data of the same type" (p. 281). These goals are met by data mining tasks such as classification, regression, clustering, summarization, dependency modeling, and change or deviation detection. Subsequent chapters demonstrate how visualization can aid users in the interactive process of knowledge discovery by graphically representing the results from these iterative tasks. Finally, examples of the usefulness of integrating visualization and data mining tools in the domain of business, imagery and text mining, and massive data sets are provided. This text concludes with a thorough and useful 17-page index and lengthy yet integrating 17-page summary of the academic and industrial backgrounds of the contributing authors. A 16-page set of color inserts provide a better representation of the visualizations discussed, and a URL provided suggests that readers may view all the book's figures in color on-line, although as of this submission date it only provides access to a summary of the book and its contents. The overall contribution of this work is its focus an bridging two distinct areas of research, making it a valuable addition to the Morgan Kaufmann Series in Database Management Systems. The editors of this text have met their main goal of providing the first textbook integrating knowledge discovery, data mining, and visualization. Although it contributes greatly to our under- standing of the development and current state of the field, a major weakness of this text is that there is no concluding chapter to discuss the contributions of the sum of these contributed papers or give direction to possible future areas of research. "Integration of expertise between two different disciplines is a difficult process of communication and reeducation. Integrating data mining and visualization is particularly complex because each of these fields in itself must draw an a wide range of research experience" (p. 300). Although this work contributes to the crossdisciplinary communication needed to advance visualization in KDD, a more formal call for an interdisciplinary research agenda in a concluding chapter would have provided a more satisfying conclusion to a very good introductory text.
With contributors almost exclusively from the computer science field, the intended audience of this work is heavily slanted towards a computer science perspective. However, it is highly readable and provides introductory material that would be useful to information scientists from a variety of domains. Yet, much interesting work in information visualization from other fields could have been included giving the work more of an interdisciplinary perspective to complement their goals of integrating work in this area. Unfortunately, many of the application chapters are these, shallow, and lack complementary illustrations of visualization techniques or user interfaces used. However, they do provide insight into the many applications being developed in this rapidly expanding field. The authors have successfully put together a highly useful reference text for the data mining and information visualization communities. Those interested in a good introduction and overview of complementary research areas in these fields will be satisfied with this collection of papers. The focus upon integrating data visualization with data mining complements texts in each of these fields, such as Advances in Knowledge Discovery and Data Mining (Fayyad et al., MIT Press) and Readings in Information Visualization: Using Vision to Think (Card et. al., Morgan Kauffman). This unique work is a good starting point for future interaction between researchers in the fields of data visualization and data mining and makes a good accompaniment for a course focused an integrating these areas or to the main reference texts in these fields."

The deployed searching and retrieving descriptors arc naturally subjective and their deployment is often restricted to the specific application domain for which the descriptors were configured. The new era of information technology imposes different kinds of requirements and challenges. Automatic extracted audiovisual features are required, as these features are more objective, domain-independent, and more native to audiovisual content. This book is a useful guide for researchers, experts, students, and practitioners; it is a very valuable reference and can lead them through their exploration and research in multimedia content and the semantic web. The book is well organized, and introduces the concept of the semantic web and multimedia content analysis to the reader through a logical sequence from standards and hypotheses through system examples, presenting relevant tools and methods. But in some chapters readers will need a good technical background to understand some of the details. Readers may attain sufficient knowledge here to start projects or research related to the book's theme; recent results and articles related to the active research area of integrating multimedia with semantic web technologies are included. This book includes full descriptions of approaches to specific problem domains such as content search, indexing, and retrieval. This book will be very useful to researchers in the multimedia content analysis field who wish to explore the benefits of emerging semantic web technologies in applying multimedia content approaches. The first part of the book covers the definition of the two basic terms multimedia content and semantic web. The Moving Picture Experts Group standards MPEG7 and MPEG21 are quoted extensively. In addition, the means of multimedia content description are elaborated upon and schematically drawn. This extensive description is introduced by authors who are actively involved in those standards and have been participating in the work of the International Organization for Standardization (ISO)/MPEG for many years. On the other hand, this results in bias against the ad hoc or nonstandard tools for multimedia description in favor of the standard approaches. This is a general book for multimedia content; more emphasis on the general multimedia description and extraction could be provided.
Semantic web technologies are explained, and ontology representation is emphasized. There is an excellent summary of the fundamental theory behind applying a knowledge-engineering approach to vision problems. This summary represents the concept of the semantic web and multimedia content analysis. A definition of the fuzzy knowledge representation that can be used for realization in multimedia content applications has been provided, with a comprehensive analysis. The second part of the book introduces the multimedia content analysis approaches and applications. In addition, some examples of methods applicable to multimedia content analysis are presented. Multimedia content analysis is a very diverse field and concerns many other research fields at the same time; this creates strong diversity issues, as everything from low-level features (e.g., colors, DCT coefficients, motion vectors, etc.) up to the very high and semantic level (e.g., Object, Events, Tracks, etc.) are involved. The second part includes topics on structure identification (e.g., shot detection for video sequences), and object-based video indexing. These conventional analysis methods are supplemented by results on semantic multimedia analysis, including three detailed chapters on the development and use of knowledge models for automatic multimedia analysis. Starting from object-based indexing and continuing with machine learning, these three chapters are very logically organized. Because of the diversity of this research field, including several chapters of recent research results is not sufficient to cover the state of the art of multimedia. The editors of the book should write an introductory chapter about multimedia content analysis approaches, basic problems, and technical issues and challenges, and try to survey the state of the art of the field and thus introduce the field to the reader.
The final part of the book discusses research in multimedia content management systems and the semantic web, and presents examples and applications for semantic multimedia analysis in search and retrieval systems. These chapters describe example systems in which current projects have been implemented, and include extensive results and real demonstrations. For example, real case scenarios such as ECommerce medical applications and Web services have been introduced. Topics in natural language, speech and image processing techniques and their application for multimedia indexing, and content-based retrieval have been elaborated upon with extensive examples and deployment methods. The editors of the book themselves provide the readers with a chapter about their latest research results on knowledge-based multimedia content indexing and retrieval. Some interesting applications for multimedia content and the semantic web are introduced. Applications that have taken advantage of the metadata provided by MPEG7 in order to realize advance-access services for multimedia content have been provided. The applications discussed in the third part of the book provide useful guidance to researchers and practitioners properly planning to implement semantic multimedia analysis techniques in new research and development projects in both academia and industry. A fourth part should be added to this book: performance measurements for integrated approaches of multimedia analysis and the semantic web. Performance of the semantic approach is a very sophisticated issue and requires extensive elaboration and effort. Measuring the semantic search is an ongoing research area; several chapters concerning performance measurement and analysis would be required to adequately cover this area and introduce it to readers."

- Abstract
- The Text REtrieval Conference (TREC), a yearly workshop hosted by the US government's National Institute of Standards and Technology, provides the infrastructure necessary for large-scale evaluation of text retrieval methodologies. With the goal of accelerating research in this area, TREC created the first large test collections of full-text documents and standardized retrieval evaluation. The impact has been significant; since TREC's beginning in 1992, retrieval effectiveness has approximately doubled. TREC has built a variety of large test collections, including collections for such specialized retrieval tasks as cross-language retrieval and retrieval of speech. Moreover, TREC has accelerated the transfer of research ideas into commercial systems, as demonstrated in the number of retrieval techniques developed in TREC that are now used in Web search engines. This book provides a comprehensive review of TREC research, summarizing the variety of TREC results, documenting the best practices in experimental information retrieval, and suggesting areas for further research. The first part of the book describes TREC's history, test collections, and retrieval methodology. Next, the book provides "track" reports -- describing the evaluations of specific tasks, including routing and filtering, interactive retrieval, and retrieving noisy text. The final part of the book offers perspectives on TREC from such participants as Microsoft Research, University of Massachusetts, Cornell University, University of Waterloo, City University of New York, and IBM. The book will be of interest to researchers in information retrieval and related technologies, including natural language processing.

- Rez. in: JASIST 58(2007) no.6, S.910-911 (J.L. Vicedo u. J. Gomez): "The Text REtrieval Conference (TREC) is a yearly workshop hosted by the U.S. government's National Institute of Standards and Technology (NIST) that fosters and supports research in information retrieval as well as speeding the transfer of technology between research labs and industry. Since 1992, TREC has provided the infrastructure necessary for large-scale evaluations of different text retrieval methodologies. TREC impact has been very important and its success has been mainly supported by its continuous adaptation to the emerging information retrieval needs. Not in vain, TREC has built evaluation benchmarks for more than 20 different retrieval problems such as Web retrieval, speech retrieval, or question-answering. The large and intense trajectory of annual TREC conferences has resulted in an immense bulk of documents reflecting the different eval uation and research efforts developed. This situation makes it difficult sometimes to observe clearly how research in information retrieval (IR) has evolved over the course of TREC. TREC: Experiment and Evaluation in Information Retrieval succeeds in organizing and condensing all this research into a manageable volume that describes TREC history and summarizes the main lessons learned. The book is organized into three parts. The first part is devoted to the description of TREC's origin and history, the test collections, and the evaluation methodology developed. The second part describes a selection of the major evaluation exercises (tracks), and the third part contains contributions from research groups that had a large and remarkable participation in TREC. Finally, Karen Spark Jones, one of the main promoters of research in IR, closes the book with an epilogue that analyzes the impact of TREC on this research field.
... 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."

- Abstract
- We live in an information age that requires us, more than ever, to represent, access, and use information. Over the last several decades, we have developed a modern science and technology for information retrieval, relentlessly pursuing the vision of a "memex" that Vannevar Bush proposed in his seminal article, "As We May Think." Faceted search plays a key role in this program. Faceted search addresses weaknesses of conventional search approaches and has emerged as a foundation for interactive information retrieval. User studies demonstrate that faceted search provides more effective information-seeking support to users than best-first search. Indeed, faceted search has become increasingly prevalent in online information access systems, particularly for e-commerce and site search. In this lecture, we explore the history, theory, and practice of faceted search. Although we cannot hope to be exhaustive, our aim is to provide sufficient depth and breadth to offer a useful resource to both researchers and practitioners. Because faceted search is an area of interest to computer scientists, information scientists, interface designers, and usability researchers, we do not assume that the reader is a specialist in any of these fields. Rather, we offer a self-contained treatment of the topic, with an extensive bibliography for those who would like to pursue particular aspects in more depth.

- Abstract
- As information becomes more ubiquitous and the demands that searchers have on search systems grow, there is a need to support search behaviors beyond simple lookup. Information seeking is the process or activity of attempting to obtain information in both human and technological contexts. Exploratory search describes an information-seeking problem context that is open-ended, persistent, and multifaceted, and information-seeking processes that are opportunistic, iterative, and multitactical. Exploratory searchers aim to solve complex problems and develop enhanced mental capacities. Exploratory search systems support this through symbiotic human-machine relationships that provide guidance in exploring unfamiliar information landscapes. Exploratory search has gained prominence in recent years. There is an increased interest from the information retrieval, information science, and human-computer interaction communities in moving beyond the traditional turn-taking interaction model supported by major Web search engines, and toward support for human intelligence amplification and information use. In this lecture, we introduce exploratory search, relate it to relevant extant research, outline the features of exploratory search systems, discuss the evaluation of these systems, and suggest some future directions for supporting exploratory search. Exploratory search is a new frontier in the search domain and is becoming increasingly important in shaping our future world.

- Abstract
- The Architecture of Cyberspace is aimed at students taking information management as a minor in their course as well as those who manage document collections but who are not professional librarians. The first part of this book looks at how users find documents and the problems they have; the second part discusses how to manage the information space using various tools such as classification and controlled vocabularies. It also explores the general issues of publishing, including legal considerations, as well the main issues of creating and managing archives. Supported by exercises and discussion questions at the end of each chapter, the book includes some sample assignments suitable for use with students of this subject. A glossary is also provided to help readers understand the specialised vocabulary and the key concepts in the design and assessment of information spaces.

- Abstract
- Interested in how an efficient search engine works? Want to know what algorithms are used to rank resulting documents in response to user requests? The authors answer these and other key information on retrieval design and implementation questions is provided. This book is not yet another high level text. Instead, algorithms are thoroughly described, making this book ideally suited for both computer science students and practitioners who work on search-related applications. As stated in the foreword, this book provides a current, broad, and detailed overview of the field and is the only one that does so. Examples are used throughout to illustrate the algorithms. The authors explain how a query is ranked against a document collection using either a single or a combination of retrieval strategies, and how an assortment of utilities are integrated into the query processing scheme to improve these rankings. Methods for building and compressing text indexes, querying and retrieving documents in multiple languages, and using parallel or distributed processing to expedite the search are likewise described. This edition is a major expansion of the one published in 1998. Neuaufl. 2005: Besides updating the entire book with current techniques, it includes new sections on language models, cross-language information retrieval, peer-to-peer processing, XML search, mediators, and duplicate document detection.

- Rez. in: Mitt. VÖB 59(2006) H.3, S.95-98 (O. Oberhauser): "Dieser Sammelband der Herausgeber A. Spink & C. Cole ist kurz vor ihrem im letzten Heft der Mitteilungen der VÖB besprochenen zweiten Buch erschienen. Er wendet sich an Informationswissenschaftler, Bibliothekare, Sozialwissenschaftler sowie Informatiker mit Interesse am Themenbereich Mensch-Computer-Interaktion und präsentiert einen Einblick in die aktuelle Forschung zum kognitiv orientierten Information Retrieval. Diese Richtung, die von der Analyse der Informationsprobleme der Benutzer und deren kognitivem Verhalten bei der Benutzung von Informationssystemen ausgeht, steht in einem gewissen Kontrast zum traditionell vorherrschenden IR-Paradigma, das sich auf die Optimierung der IR-Systeme und ihrer Effizienz konzentriert. "Cognitive information retrieval" oder CIR (natürlich geht es auch hier nicht ohne ein weiteres Akronym ab) ist ein interdisziplinärer Forschungsbereich, der Aktivitäten aus Informationswissenschaft, Informatik, Humanwissenschaften, Kognitionswissenschaft, Mensch-Computer-Interaktion und anderen informationsbezogenen Gebieten inkludiert.
CIR Concepts - Interactive information retrieval: Bringing the user to a selection state, von Charles Cole et al. (Montréal), konzentriert sich auf den kognitiven Aspekt von Benutzern bei der Interaktion mit den bzw. der Reaktion auf die vom IR-System ausgesandten Stimuli; "selection" bezieht sich dabei auf die Auswahl, die das System den Benutzern abverlangt und die zur Veränderung ihrer Wissensstrukturen beiträgt. - Cognitive overlaps along the polyrepresentation continuum, von Birger Larsen und Peter Ingwersen (Kopenhagen), beschreibt einen auf Ingwersens Principle of Polyrepresentation beruhenden methodischen Ansatz, der dem IR-System ein breiteres Bild des Benutzers bzw. der Dokumente vermittelt als dies bei herkömmlichen, lediglich anfragebasierten Systemen möglich ist. - Integrating approaches to relevance, von Ian Ruthven (Glasgow), analysiert den Relevanzbegriff und schlägt anstelle des gegenwärtig in IR-Systemverwendeten, eindimensionalen Relevanzkonzepts eine multidimensionale Sichtweise vor. - New cognitive directions, von Nigel Ford (Sheffield), führt neue Begriffe ein: Ford schlägt anstelle von information need und information behaviour die Alternativen knowledge need und knowledge behaviour vor.
CIR Processes - A multitasking framework for cognitive information retrieval, von Amanda Spink und Charles Cole (Australien/Kanada), sieht - im Gegensatz zu traditionellen Ansätzen - die simultane Bearbeitung verschiedener Aufgaben (Themen) während einer Informationssuche als den Normalfall an und analysiert das damit verbundene Benutzerverhalten. - Explanation in information seeking and retrieval, von Pertti Vakkari und Kalervo Järvelin (Tampere), plädiert anhand zweier empirischer Untersuchungen für die Verwendung des aufgabenorientierten Ansatzes ("task") in der IR-Forschung, gerade auch als Bindeglied zwischen nicht ausreichend mit einander kommunizierenden Disziplinen (Informationswissenschaft, Informatik, diverse Sozialwissenschaften). - Towards an alternative information retrieval system for children, von Jamshid Beheshti et al. (Montréal), berichtet über den Stand der IR-Forschung für Kinder und schlägt vor, eine Metapher aus dem Sozialkonstruktivismus (Lernen als soziales Verhandeln) als Gestaltungsprinzip für einschlägige IR-Systeme zu verwenden. CIR Techniques - Implicit feedback: using behavior to infer relevance, von Diane Kelly (North Carolina), setzt sich kritisch mit den Techniken zur Analyse des von Benutzern von IR-Systemen geäußerten Relevance-Feedbacks - explizit und implizit - auseinander. - Educational knowledge domain visualizations, von Peter Hook und Katy Börner (Indiana), beschreibt verschiedene Visualisierungstechniken zur Repräsentation von Wissensgebieten, die "Novizen" bei der Verwendung fachspezifischer IR-Systeme unterstützen sollen. - Learning and training to search, von Wendy Lucas und Heikki Topi (Massachusetts), analysiert, im breiteren Kontext der Information- Seeking-Forschung, Techniken zur Schulung von Benutzern von IRSystemen.
Sämtliche Beiträge sind von hohem Niveau und bieten anspruchsvolle Lektüre. Verallgemeinert formuliert, fragen sie nach der Verknüpfung zwischen dem breiteren Kontext des Warum und Wie der menschlichen Informationssuche und den technischen bzw. sonstigen Randbedingungen, die die Interaktion zwischen Benutzern und Systemen bestimmen. Natürlich liegt hier kein Hand- oder Lehrbuch vor, sodass man - fairerweise - nicht von einer systematischen Behandlung dieses Themenbereichs oder einem didaktischen Aufbau ausgehen bzw. derlei erwarten darf. Das Buch bietet jedenfalls einen guten und vielfältigen Einstieg und Einblick in dieses interessante Forschungsgebiet. Fachlich einschlägige und größere allgemeine Bibliotheken sollten es daher jedenfalls in ihren Bestand aufnehmen. Schon die Rezension des oben zitierten zweiten Buches des Herausgeber-Duos Spink-Cole enthielt einen kritischen Hinweis auf das dortige Sachregister. Der vorliegende Band erfordert noch stärkere Nerven, denn der hier als "Index" bezeichnete Seitenfüller spottet geradezu jeder Beschreibung, umso mehr, als wir uns in einem informationswissenschaftlichen Kontext befi nden. Was soll man denn tatsächlich mit Einträgen wie "information" anfangen, noch dazu, wenn dazu über 150 verschiedene Seitenzahlen angegeben werden? Ähnlich verhält es sich mit anderen allgemeinen Begriffen wie z.B. "knowledge", "model", "tasks", "use", "users" - allesamt mit einer gewaltigen Menge von Seitenzahlen versehen und damit ohne Wert! Dieses der Leserschaft wenig dienliche Register ist wohl dem Verlag anzulasten, auch wenn die Herausgeber selbst seine Urheber gewesen sein sollten. Davon abgesehen wurde wieder einmal ein solide gefertigter Band vorgelegt, der allerdings wegen seines hohen Preis eher nur institutionelle Käufer ansprechen wird."
Weitere Rez. in: JASIST 58(2007) no.5, S.758-760 (A. Gruzd): "Despite the minor drawbacks described, the book is a great source for researchers in the IR&S fields in general and in the CIR field in particular. Furthermore, different chapters of this book also might be of interest to members from other communities. For instance, librarians responsible for library instruction might find the chapter on search training by Lucas and Topi helpful in their work. Cognitive psychologists would probably be intrigued by Spink and Cole's view on multitasking. IR interface designers will likely find the chapter on KDV by Hook and Borner very beneficial. And students taking IR-related courses might find the thorough literature reviews by Ruthven and Kelly particularly useful when beginning their own research."

- Abstract
- Libraries have always been an inspiration for the standards and technologies developed by semantic web activities. However, except for the Dublin Core specification, semantic web and social networking technologies have not been widely adopted and further developed by major digital library initiatives and projects. Yet semantic technologies offer a new level of flexibility, interoperability, and relationships for digital repositories. Kruk and McDaniel present semantic web-related aspects of current digital library activities, and introduce their functionality; they show examples ranging from general architectural descriptions to detailed usages of specific ontologies, and thus stimulate the awareness of researchers, engineers, and potential users of those technologies. Their presentation is completed by chapters on existing prototype systems such as JeromeDL, BRICKS, and Greenstone, as well as a look into the possible future of semantic digital libraries. This book is aimed at researchers and graduate students in areas like digital libraries, the semantic web, social networks, and information retrieval. This audience will benefit from detailed descriptions of both today's possibilities and also the shortcomings of applying semantic web technologies to large digital repositories of often unstructured data.

- Rez. in: Mitt. VÖB 59(2006) H.3, S.90-93 (O. Oberhauser): "What a marvellous book! [dies vorwegnehmend als Quintessenz der folgenden Rezension und auch für den englischsprachigen Verlag gedacht]. Den drei Herausgeberinnen, die an den Universitäten von Washington (Seattle, WA), Missouri (Columbia, MO) und Western Ontario (London, Kanada) lehren, ist das seltene Kunststück geglückt, einen Band zu erstellen, der nicht nur als mustergültige Einführung in die Thematik human information behaviour zu dienen vermag, sondern gleichzeitig auch als Nachschlagewerk zu den vielfältigen theoretischen Ansätzen innerhalb dieser bedeutenden Teildisziplin der Informationswissenschaft herangezogen werden kann. Wie sie selbst in der Danksagung feststellen, ist das Buch "a collaborative work of the information behavior community" (S. xvii), wobei die editorische Leistung vor allem darin lag, 85 Beitragende aus zehn Ländern zu koordinieren bzw. zur Abfassung von 72 Artikeln von jeweils ähnlicher Länge (bzw. Knappheit und Kürze), Gestaltung und Lesbarkeit zu veranlassen. Unter diesen 85 Beitragenden ist im übrigen alles versammelt, was in dieser Teildisziplin Rang und Namen hat, mit Ausnahme der leider bereits verstorbenen Soziologin Elfreda A. Chatman, einer der einflussreichsten Theoretikerinnen im Bereich des Informationsverhaltens, deren Andenken das Buch auch gewidmet ist.
Im Gegensatz zur früher üblichen Praxis, Informationsverhalten auf die Aktivitäten der Informationssuche zu beschränken, folgt man heute Tom Wilsons Definition, wonach es sich dabei um "the totality of human behaviour in relation to sources and channels of information, including both active and passive information-seeking, and information use" handelt, bzw. jener von Karen Pettigrew [nunmehr Fisher] et al., "how people need, seek, give and use information in different contexts". Im Laufe der letzten Jahre, ja schon Jahrzehnte, hat sich dazu ein fast nicht mehr überschaubarer Bestand an Literatur angesammelt, der sich sowohl aus theoretischen bzw. theoretisierenden, als auch aus auch praktischen bzw. empirischen Arbeiten zusammensetzt. Einige wenige dieser theoretischen Ansätze haben weite Verbreitung gefunden, werden in Studiengängen der Informationswissenschaft gelehrt und tauchen in der laufend veröffentlichten Literatur immer wieder als Basis für empirische Untersuchungen oder modifizierende Weiterentwicklungen auf. Das Buch beginnt mit drei Grundsatzartikeln, die von herausragenden Vertretern des gegenständlichen Themenbereichs verfasst wurden. Im ersten und längsten dieser Beiträge, An Introduction to Metatheories, Theories and Models (S. 1-24), gibt Marcia J. Bates (Los Angeles, CA), zunächst eine wissenschaftstheoretische Einführung zu den drei im Titel genannten Begriffen, nicht ohne darauf hinzuweisen, dass der Großteil der theoretisierenden Ansätze in unserer Disziplin erst dem Modellstadium angehört. Am Beispiel des Principle of Least Effort zeigt sie, dass selbst für diesen am besten abgesicherten Befund der Forschung zum Informationsverhalten, keine ausreichende theoretische Begründung existiert. In der Folge versucht Bates, die in der Informationswissenschaft gängigen Metatheorien zu identifizieren und gelangt dabei zu der folgenden Kategorisierung, die auch als Bezugsrahmen für die Einordnung der zahlreichen in diesem Buch dargestellten Modelle dienen kann:
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."

- Abstract
- The second edition of Understanding Search Engines: Mathematical Modeling and Text Retrieval follows the basic premise of the first edition by discussing many of the key design issues for building search engines and emphasizing the important role that applied mathematics can play in improving information retrieval. The authors discuss important data structures, algorithms, and software as well as user-centered issues such as interfaces, manual indexing, and document preparation. Significant changes bring the text up to date on current information retrieval methods: for example the addition of a new chapter on link-structure algorithms used in search engines such as Google. The chapter on user interface has been rewritten to specifically focus on search engine usability. In addition the authors have added new recommendations for further reading and expanded the bibliography, and have updated and streamlined the index to make it more reader friendly.

- Abstract
- The World Wide Web is rapidly filling with more text than anyone could have imagined even a short time ago, but the task of isolating relevant parts of this vast information has become just that much more daunting. Richard Belew brings a cognitive perspective to the study of information retrieval as a discipline within computer science. He introduces the idea of Finding Out About (FDA) as the process of actively seeking out information relevant to a topic of interest and describes its many facets - ranging from creating a good characterization of what the user seeks, to what documents actually mean, to methods of inferring semantic clues about each document, to the problem of evaluating whether our search engines are performing as we have intended. Finding Out About explains how to build the tools that are useful for searching collections of text and other media. In the process it takes a close look at the properties of textual documents that do not become clear until very large collections of them are brought together and shows that the construction of effective search engines requires knowledge of the statistical and mathematical properties of linguistic phenomena, as well as an appreciation for the cognitive foundation we bring to the task as language users. The unique approach of this book is its even handling of the phenomena of both numbers and words, making it accessible to a wide audience. The textbook is usable in both undergraduate and graduate classes on information retrieval, library science, and computational linguistics. The text is accompanied by a CD-ROM that contains a hypertext version of the book, including additional topics and notes not present in the printed edition. In addition, the CD contains the full text of C.J. "Keith" van Rijsbergen's famous textbook, Information Retrieval (now out of print). Many active links from Belew's to van Rijsbergen's hypertexts help to unite the material. Several test corpora and indexing tools are provided, to support the design of your own search engine. Additional exercises using these corpora and code are available to instructors. Also supporting this book is a Web site that will include recent additions to the book, as well as links to sites of new topics and methods.

- Abstract
- Extracting content from text continues to be an important research problem for information processing and management. Approaches to capture the semantics of text-based document collections may be based on Bayesian models, probability theory, vector space models, statistical models, or even graph theory. As the volume of digitized textual media continues to grow, so does the need for designing robust, scalable indexing and search strategies (software) to meet a variety of user needs. Knowledge extraction or creation from text requires systematic yet reliable processing that can be codified and adapted for changing needs and environments. This book will draw upon experts in both academia and industry to recommend practical approaches to the purification, indexing, and mining of textual information. It will address document identification, clustering and categorizing documents, cleaning text, and visualizing semantic models of text.
